Customizations and Upgrading Solid Edge

Tuesday, April 30th, 2013
With the ST6 coming one thing is certain…changes are coming.  This next topic will discuss how to transition from ST4 to ST5 (and as well can be used for ST6 upgrades) in relation to the customizations in Solid Edge.
There are certain things that a CAD Administrator can set up for you and share amongst the masses.  If you do not have the luxury of a CAD Administrator, it is very worthwhile to have users share setups.  It would be best if there was only one person setting things up as this keeps everything to a standard.
S
Solid Edge can, quite easily, bring toolbar settings from version to version.  The toolbars can be re-used as it were.  Also to note is the fact that these customized toolbars can be deployed on a user specific basis as well as a base company template type setting.  For instance, a company standard toolbar customization could be deployed and the user would then be allowed to take it from there.  Every company has certain functions that vary from what SE sets up out of the box.  Companies vary as well.  Users vary even further.  It would be worthwhile to invest the time once to set up company templates and environment settings.  If you do it once, there would be years of savings moving forward.
S
The image below illustrates the settings you can set up and take with you from version to version.  Keyboard, Quick access, Ribbon, and Radial Menu options can all be set up.

Screenshot of "Customize" Menu

The next sessions we will discuss how to set up everything.  I always like to have the “Previous Window” (in Draft for this example).  These are the steps I would go through.  Open a draft file, although you can do this without opening a file.  Select the down arrow beside the QAT and go to “Customize the Ribbon”.
S
The following dialogue box opens:
Expand the “View” tab on the left and expand the “Home” tab on the right to look like the image below.
S
Have “Previous View” selected on the left and select “Window” from under the home tab on the right and then hit the “Add” button.  It should look like this:
S
Close the dialogue box and you should notice on your Home toolbar that the Previous View icon has been added.  You may be asked if you want to save this if you need to create a new theme or you could save it to an existing customization.
You can also right click and the following menu shows up allowing you to set the options for the new icon:
S
These settings are saved in the following locations in ST5:
Vista/Win 7:
C:\Users\”username”\AppData\Roaming\Unigraphics Solutions\Solid Edge\Version 105\Customization\
XP:
C:\Documents and Settings\”username”\Application Data\UnigraphicsSolutions\Solid Edge\Version 105\Customization\
Windows 7 shown below for reference:
These settings can be shared between different users and computers.  As you can see, each theme is in a different folder and each type of customization (QAT, Radial Menus, Ribbon, ect) is in a separate file.  Because it is external to the install directory of Solid Edge and is not in the registry these customizations traverse updates to the software version.
S

Quicksheets

Tuesday, November 20th, 2012

A “Quicksheet” is a template of drawing views that are not linked to a model. You can then drag a model from the Library tab or from Windows Explorer onto the template, and the views populate with the model.  If you have standard views on a particular size of drawing, for example, you can have the Draft preconfigured to populate itself based on the model you place on the sheet.

You will to need to set up a Draft sheet (but do not use production drawing as the drafting information will be removed upon save) with your views and other items such as Parts Lists.

1. Go to the SE Application button

2. From the Application menu, choose the “Create Quicksheet Template” command.

3. Save the file to a location and give it a name that easily identifies it.  It is best to place this on a network area other users can get to if it is useful to share the Quicksheet.   It is also best to locate it in a similar area to where the company templates for SE reside.

* Almost all view properties, including general properties, text and color properties, and annotation properties, are maintained. However, some display properties, such as selected parts display, Show Fill Style, and Hidden Edge Style, are not maintained.

Now a Quicksheet template has been created, but how do we use it?

1. Open your Quicksheet template (either through Windows Explorer or if you set up your User Templates and placed the Quicksheets in that location hit New>Quicksheet> and select your Quicksheet).

2. Drag and drop your desired Part or Assy onto the sheet from Windows Explorer or through the Library tab in Solid Edge.

3. Solid Edge will place the geometry and will be ready for the next steps.

Integrated Modeling in Solid Edge

Monday, November 19th, 2012suggest

With any new technology, you have your early adopters. This is followed by a general acceptance of the new technology, and of course, you always have your hold outs or late adopters.  Solid Edge ST and ST2 appealed to the earlier adopters for synchronous technology. With ST3, ST4 and now ST5, we are seeing most of our customers starting to use synchronous modeling. This of course has led to many questions. The most asked question is; “Should I use synchronous or ordered modeling?” The answer to this is yes.

One of the unique qualities of Solid Edge is that you are not locked into using synchronous or ordered modeling. Integrated modeling allows you to use both synchronous features and ordered features within the same part or sheet metal model. As a rule of thumb, I encourage users to start with synchronous modeling. If they run into some issues that can’t be addressed with synchronous features, they can switch to the ordered paradigm to complete
the model. Let me illustrate this with the following example:

I wish to model the sheet metal cover shown in the following image.

I start in the synchronous paradigm and create a tab, for the top of the cover.

I then add 2 synchronous flanges, in one step, to create the back and left side of the cover.

One of the current limitations, in synchronous sheet metal modeling, is that you cannot drive a flange along a circular edge. Realizing this I will hold off creating the front and right sides until the end, when I will use an ordered feature.

I next use 2 bead synchronous features to create the slots at the top of the part.

I then transition to the ordered paradigm to complete the model.

I use the ordered Contour Flange command to create the front and right face of the cover.

The nice thing about this approach is that it still allows me to modify the model using the synchronous Move/Rotate command.

Live Rules and all the other synchronous editing tools still apply to the model.

As I modify the model, synchronous features update instantly, followed by the re-computing of any ordered features.

For those of you who attended our productivity seminars, you saw this demonstrated live. Other users have learned this process in one of our many synchronous modeling courses, offered over the last year.

This is just one of many examples where Integrated Modeling allows you to benefit from the new synchronous technology, while still utilizing some of the tried and true methods of the ordered technology.  As Solid Edge continues to develop the synchronous features, you may find that you’ll use less integrated modeling. But for now this provides you with a reliable and safe platform to further advance your adoption of this amazing new modeling paradigm we call synchronous technology.

If you’d like to learn more about integrated modeling, you can attend one of our synchronous modeling courses. For more information visit our website at http://www.designfusion.ca//synchronous_tech_course.php. New 2013 courses will be added to our schedule soon.

Editing Part/SM Operations in Assembly

Monday, November 5th, 2012
In ST5 you can now perform edit operations, from the assembly environment, without first in-place-activating to enter the model directly.  Things you can do:
  • Locate, select and edit of ordered features
  • Edit synchronous procedural features
  • Delete synchronous face-sets and ordered features
  • Move face-sets (sync feature) in synchronous parts
Let’s take a look!
Firstly, ordered features are now selectable via the Face Priority select option. (remember hotkey combo is CTL + Spacebar)
Notice in the example below that “Protrusion 1” is available from the Quickpick options in assembly now.
Once selected, “Protrusion 1” has its options displayed for going directly into the features parameters.
Select whatever you would like to edit and SE will take you directly there.  Once complete, just close and return.  This will take you back to where you were in the assembly.
This saves time from previous versions by allowing you to go directly to what you want to modify and brings you back to the assembly reducing the number of mouse clicks.
Editing synchronous procedural features from the assembly level does not in-place-activate the user into the part.  Procedural features are things such as Patterns, Thin wall, Helix, Hem, Dimple, Louver, Drawn cutout, Bead, Gusset, and Etch.  These are editable directly in the assembly.
Using Face Select again, “Louver 1” is selected.
The handle for the procedural features shows up.  If selected we are presented with the following options.
Also, if we were to select the adjacent lover we would be presented with the following options:
Notice that the option to edit the pattern is there.  I know what the usual next question would be “How would I know how to edit the parent of the pattern?”.  Notice the option for “Louver 14”.  If you were to select it, you would be presented with the same options as previously mentioned.
We select “Pattern 1” and now we can modify the parameters that define the pattern.
Once selected, click on the PMI callout “Pattern 2 x 4” and we will get the following options:
Notice we have not left the Assembly environment.
One thing to note about this type of editing: Procedural Feature profile editing requires in-place-activating first.  Also, there is no access to the profile handle from within the assembly.
Happy Edging!

NX – Create a family of standard parts (Excel)

Wednesday, July 4th, 2012

Design Intent:  The most common use of Part Families is to define a standard library part that has many variations.

     1.  Create an hexbolt  

     2.  Rename the expression that you want to keep

             a: Width = the radius of the cap

             b: Length = length of screw

     3.  Define the columns for the Family Table.

 >Choose Tools→Part Families from the main menu bar.

 >Make sure the Importable Part Family Template option is  cleared.

 >Click OK on the Warning dialog box.

 >Select the width expression from the top window of the Part Families dialog box.

 >Click the Add Column button.

 >Select the lenght expression from the top window of the Part Families dialog box.

 >Click the Add Column button.

Note:  Instead of choosing, Add Column, you could just double-click on the expression name in the Available Columns list, i.e. head_dia.

> Change the option menu at the top of the dialog box from Expressions to Features.

> Double-click chamfer from the top list of the Part Families dialog box.

Note:  The order in which you select the attributes determines the order of columns in the spreadsheet.

Tip:  In production, you would specify a writable folder for the Family Save Directory, but it is not necessary for this activity since you are not creating Part Family Member files.

     4.  Create the family table.

  > Click the Create button from the bottom portion of the Part Families dialog box.

 

 > Type in a few values

    5.  Verify a family member

 > Select a cell in row 3.

 > From the spreadsheet ADD-INS menu bar, choose PartFamily→Verify Part.

The NX session becomes active and the family member is displayed in the graphics window.

 > Click Resume in the Part Families dialog box.

Warning:  The Part Families dialog box may be obscured, if so, click anywhere in the NX window.

     6.  Save the Part Family and the template part.

 > From the spreadsheet menu bar, choose PartFamily→Save Family.

Note:  The Save Family option internally stores the spreadsheet data within the template part file. It does not save the template part file itself.

Note:  In order to save the template part containing this newly created Part Family Spreadsheet, you would also choose File→Save.

Since we do not use this part anywhere else we are not going to do that.

     7.  Close all parts.

Is Training Worth It? – Calculate your Return On Investment

Tuesday, March 27th, 2012suggest

In today’s competitive market, businesses are looking to get the most out of their employees, systems, software and machines. With the ever changing technology, this can be somewhat challenging.  Too often companies will invest in new technology but not invest in the training on the new technology. The most common reasons for this are:

  • - I don’t have the time to take the training.
  • - I can’t afford the cost of the training.
  • - I can train myself for free.
  • - I train one employee and he/she can train the rest.
  • - I have a high staff turn over and it’s not worth training them.

As a trainer I have heard all these excuses and more. They all essentially evolve around cost. Therefore, it is important that companies look at both the ROI of professional training and the cost of not taking professional training.

How to calculate the ROI of professional training

To calculate the ROI, you need to determine the total cost of the training course and compare it to the total financial benefit derived from the course. The cost of the course can be determined as shown below:

Cost of course                   = $ 2000

Salary of employee           =  $1000

Travel & Living Expenses  = $1000

Total cost of course           = $4000

The financial benefit derived from the course can be a little harder to determine and often depends on the individual. Below is a one potential example;

Suppose John Smith attends a course on a CAM software package. In this course he learns new and faster methods to create programs. Assuming a modest 10% increase in his program generation skills, we can start calculating the financial benefit. If John makes $25 per hour and he works 50 weeks a year week, allowing 2 weeks for vacation, the company pays him $50,000. If he works 10% faster the company’s immediate savings is 50,000 x 0.10 = $5000. We can also assume that John’s programs will be more efficient, saving machine time, cutter wear, and possibly less manual finishing work. His improved knowledge may also lead to fewer errors in the programs, resulting in less scrap. You may also want to consider any extra profits obtained by the increase efficiency. In other words John will be able to produce 10% more work from which the company will profit. So in John’s example we can calculate the financial benefit as follows:

Estimated savings from improved output                     = $ 5000

Estimated savings from downstream operations         = $ 2000

Estimated savings from reduced rework and scrap   = $ 1000

Estimated additional profit from improved efficiency    = $ 2500

Total financial benefit                                  = $ 10500

Using the following formula to calculate the ROI,

Net gain (total benefit-total costs) = ____ X 100 =____
  total costs  

we get an ROI of 162.5. Clearly this would justify John taking the course, especially when you consider that the financial benefit estimates are very conservative.

You can also view this from another direction. What is the company’s cost if an employee doesn’t take professional training?

Cost of not taking training

Let’s assume that you hire a new designer. This designer has CAD experience but does not know your CAD system. You hand him\her a manual or some tutorials and have him\her learn the system on their own. From the previous example we can assume that you are saving $4000 dollars in training. But how much are you really saving?

Although estimates vary on the topic of study, many agree that 1 hour of professional training could be equal to as many as 16 hours of teaching yourself. In other words you could spend up to 2 days reading, experimenting and learning a process that a professional trainer could teach you in 1 hour. If we extend this model we have one week of professional training = 16 weeks of self teaching. The cost to the company at $25 per hour is:

640 hours (16 weeks) x $25  =  $16,000

You also have to factor in the lost time in production for 15 of those 16 weeks that the new designer is not producing because the are still trying to learn the software. Any mistakes made through this process will also have a ripple effect throughout the company, costing more time and money. You also have to consider lost production time from any experienced employees who may be mentoring the new employee. If the experienced employee spends an average of 20% of his time helping the new employee you will lose one full week of man hours in every 5 weeks.

So for a conservative estimate, let’s assume that a new employee can learn the CAD package in 10 weeks with some assistance from experienced employees. Each week the new employee improves his/her output by 10% per week. The cost to the company can be calculated as follows:

Cost of no productive work over 10 weeks is:

  New Employee Experienced Employee
Week 1 1000 200
Week 2 900 200
Week 3 800 200
Week 4 700 200
Week 5 600 200
Week 6 500 200
Week 7 400 200
Week 8 300 200
Week 9 200 200
Week 10 100 200

Total cost of lost production  =     5500  +  2000 

                                                  =     7500 

Remember you still have to factor in the cost of fixing any training errors and the downstream effect of each error. If we assume a modest 5 errors, at an average cost of $500 per error, this results in:

Total cost of lost production = 10,000

Keep in mind that the cost could be much higher depending on the new employee’s ability to teach him/her self, and how many errors are made in the process.

Finally, you’ll have to wonder if the self taught employee has learnt the most efficient use of the software. With today’s software there are often several methods to achieve the same desired results. Each method has advantages and disadvantages depending on downstream factors. Too often self taught individuals find one method to solve a problem and use it, without further investigation to see if a more efficient way exists.  A good professional trainer will teach the different methods highlighting the situations where each method is most efficient.

Other excuses

Some companies have chosen to train one employee and have him/her train the others. They look at this as a cost savings to the company. Although this may appear to save you money you have to factor in the cost of using the first employee as your trainer. Every time he/she is training other employees, he/she is not producing work. Plus the assumption is being made that this employee has learned and retained the same knowledge as the professional trainer. This is often a false assumption, leaving the company paying almost a similar cost for a lower standard of training.

I’ve saved my favorite excuse for last. Some companies will not pay for professional training because they have too high of a staff turn around. It has been proven time and again that stress levels rise in adults when they have to learn something new. If you combine the stress for self teaching with the daily stress of the workplace, you may be contributing to the staff turn around. By providing professional training in a setting designed for learning, the employee will learn, without the work stress, and return to work with the proper skills.

Conclusion

When you actually take the time to do an honest, realistic cost analysis, it quickly becomes clear that sending your employees for professional training is a good investment.  The above examples are very conservative, yet they clearly show the advantage to professionally training your staff. Although it may be difficult to free up time and money to provide professional training, the cost of not doing so will be greater in the long term.

A well-trained employee is more likely to be satisfied with the company he\she works for, which in many cases means he\she will be less likely to leave to find a job elsewhere.  The payback is not just in a few months or a year. Instead, it can be a lifetime of service and reduced operating costs.
