    Macro to Create Folders by parts' volume/weights

    Michael Fernando

      I got a large imported assembly through Parasolid with over 2000 parts. I would like to create folders in the assembly FeatureManager with similar parts so that I could simplify this assembly by suppressing the folders with insignificant components scattered all over.

      Currently I use Assembly Visualisation’s Mass/volume property to bulk select them and create folders; this is a manual process which takes a long time to complete.

      I’m sure someone has thought about this process before. Has anyone made a macro to automate this process?

          Which version of SOLIDWORKS you're using? If 2017 or above then try Shorten Assembly FeatureManager Tree


          Other option would be to save the assembly as part file and convert that part into weldment. Now take advantage of cut list to group them

            I’ve created sub assemblies, but the part names are just a serial # without an order. Hence, I would like to create folders within those subassemblies containing parts with similar part volumes. Folder name could be “Vol_##.###” in ascending order where I could check the values and cleanup further.


            I’m not a programmer and is this possible? Maybe I should submit an ER for this.

                This is certainly possible.  I doubt an ER will get any traction at all because the macro is simple and the number of people who need it is likely quite small.


                Can you post an example parasolid? Preferably one that makes surfaces as you mentioned...

                    Here is a simplified sub-assembly.

                        Please try on this Sub-assembly with Virtual components.
