Hi to everyone

I'd like to ask if it's possible to read a custom property value from main assembly in to sub assembly

Thank you for your time

Regards

Yes you can do that via macro but you need to run the macro in case the property changes.

  Hi Deepak
  Thank you for your answer,
  but i don't know about the macros,
  and i think this is for more advance users than me, which i am a simply designer.
  Is there any possibility to help me more ?
  Thank you for your time
  regards

    I'll try to put something soon. Can you give more details on which property you want to copy over? And is that a custom or config property?

Hello,

If the assembly's custom property can be made into a global variable then this may be possible using exported/imported equations.

If so:
1. From the assembly file:
  Create the global variable (GV) in the Equations dialog.
  If you wish to link a custom property to this global variable, enter in the "Value/Text Expression" column: "GVname@AssemblyFileNameWithExtension" (this whole thing must quoted).
  It's my understanding that a global variable can drive a custom property, a property cannot drive a GV (I could be wrong about this.)
  On the right side of the Equations dialog, click the Export button.
  By default "equations.txt" is offered, but I suggest naming (and saving) this text after the assembly file name (with a txt extension instead).
  In the Export Equations dialog that pops up next, check/uncheck which entities you wish to export. In this case, only check the GV.
2. Swicth to your subpart/subassembly file:
  Open the Equations dialog as above except this time click the Import button.
  Navigate to and select the text file you just created.
  Since the assembly's GV is the only entity to import, you don't need to decide which, just make sure the assembly's GV is checked and click OK.
  The assembly's GV is now a GV in the subpart Equations dialog. It's linked so this will update when the assembly updates.
  If you wish to create a custom property in the subpart, follow step 1.1 above above except use the subpart's file name.
3. Unless you need to delete the linkage, don't touch the GV in the subpart.
4. Don't modify the text file manually either,
I hope this helps.

Kevin

  Hi Kevin
  Thank you very much for your answer.
  I followed your instructions step by step but when i importing the GV into sub assembly equation table ,it's give me an error about this.
  Am i doing something wrong? Please correct me
  Thank you for your time
  PS I send a screenshot (scr21) to see it

    Hello,
    
    I don't know why your workflow didn't complete, but here is mine:
    
    Equations dialog in assembly "FakeFrameAssy.SLDASM", create a global variable:
    Custom properties dialog in assembly "FakeFrameAssy.SLDASM", create a custom property linked to the global variable:
    Equations dialog in assembly "FakeFrameAssy.SLDASM", click Export button.
    Rename "equations.txt" to match your assembly's file name.
    Save the text file in the assembly's folder.
    This dialog displays. Check only the items you wish to export and click Export.
    Equations dialog in assembly "FakeBracket.SLDPRT", click Inport button.
    Leave the GV checked and click Import. Select the assembly's exported text file.
    The assembly's GV is created in the part's list of GVs, but is grayed out and can't be modified:
    In the part's custom properties, create a custom property using the assembly's GV name and the part's file name:
    
    Remember, any edits must only be made to the assembly's global variable to maintain the linkage.
    
    I hope this helps.

      Kevin hi again
      Ok all of these but i have another question for you if you please
      What are we doing if we have instant of a value ,an equation in the value/equation field. How can we take the value of an equation ?
      For more explanation see the scr(23)
      Regards
      PS I apologize if I get tired

You can link dim to Global Variable and GV directly to Custom Property. (see attach)
