what is the solidworks api
What is the SolidWorks API?
  • Application Programming Interface.
    • Allows other programs to access SolidWorks data and/or control SolidWorks.
    • Examples: SolidWorks Add-Ins
      • Cosmos, Toolbox, PhotoWorks, PDM Works, PDM Works Enterprise
  • Why?
    • Allow third party vendors to build applications that access SolidWorks and SolidWorks data.
    • Lets SolidWorks focus on their core products.
  • SolidWorks Add-Ins have API’s.

justification to write a macro
Justification to write a macro:
  • Define your needs.
    • What is the purpose of macro?
    • How often will you use it?
      • The more you use it, the more time you will save
  • Does it already exist?
    • Is there something available that’s close to what I need?
    • Can I modify something I already have?
    • Examples files:
      • Help file
      • SolidWorks Website
      • Lenny’s SolidWorks Resources
justification to write a macro1
Justification to write a macro:
  • Example #1 - New Macro - Document Export
    • Scope: * Export documents to different file types.

* Drawings, Models, Configurations

* 20 models to create 300 exported files

    • Problems via manual way - Manual process, Repetitive, Time consuming, user input required at all steps!
      • Did I export all configurations?
      • Selecting file type by hand every time.
      • Consistent configuration naming.
      • Estimate time to complete: 12-14 Hours
    • Time comparison:
      • Time to write: 8 Hours
      • Automated: 1.5 Hours
      • Saved first use: 10-12 Hours
    • Macro can be reused many, many times.
justification to write a macro2
Justification to write a macro:
  • Example #1 – Modify Macro – Change custom property value.
    • Scope: * All documents require change, addition or

removal of a custom property.

* 1000’s of files.

* Found macro on internet, can modify for use.

    • Problems via manual way - Manual process, Repetitive, Time consuming, user input required at all steps!
      • Did I change all documents?
      • Did I make the right changes?
      • Estimate time to complete: 20+ Hours
    • Time comparison:
      • Time to modify macro: 15 Minutes
      • Automated: 2.5 Hours
      • Saved first use: 17+ Hours
    • Macro can be customized and reused many, many times.
tips learning
Tips: Learning
  • Learn by example.
    • Find a good macro, and study how it works.
    • Use [F8] in VB Editor to step thru code line-by-line.
  • Experiment
    • Write “do nothing” macros for Visual Basic or SolidWorks API
      • Learn functions you haven’t used before.
      • Develop your own functions or common routines.
      • Test “What If” scenarios.
    • Save your code for later use.
  • Start small and work your way up.
    • Write and test small portions of code before continuing to larger portions.
    • Start with a “basic” program, then add more functionality and flexibility later.
tips sample code
Tips: Sample Code
  • Add comments to your code
    • Helps you and others understand what you did, and why.
    • Helps you remember what you did.
    • Identify what routines are doing.
  • Use existing code
    • Don’t re-invent the wheel.
    • Saves time and your effort.
    • Keep sample code on hand for later use.
  • Know that there are multiple ways to complete tasks.
    • Conditional statements
      • If … Then, Else, End If - True/False
      • Select Case …., End Case - Response based on value.
      • For …. Next - Set number of times to do.
      • Do While …. End Loop - Don’t know how many times.
tips distribution
Tips: Distribution
  • Think about other people who may be using your macros.
  • Used for other needs than initially intended.
  • User customization of existing macro.
    • Not ever user will know how to modify your macro.
    • External settings file for modifiable default settings.
      • Macro defaults if settings file is not found.
  • Different companies have standards, procedures and needs.
  • Capable of running on different versions of SolidWorks
    • API can check what version of SolidWorks is in use.
tips getting help
Tips: Getting Help
  • SolidWorks API Help File
  • Help forums.
  • SolidWorks API Support.
    • SolidWorks API functionality only.
  • Be specific!
    • Repeatable problem.
      • Steps leading up to problem
    • Specific conditions lead to problem
      • Identify specific conditions.
    • Identify specific problem you are experiencing.
    • Don’t send complete macro. Provide simple code to demonstrate.
  • Don’t expect help with programming techniques.
