You can use the Open dialog box to open a third-party native CAD file in the SOLIDWORKS software. When you open a third-party part, a new SOLIDWORKS part is created and the third-party file is inserted as a derived or a base part in it.
To open a third-party native CAD file into SOLIDWORKS:
- Click Open
(Standard toolbar) or .
- In the dialog box, browse to drive letter:\Users\Public\Public Documents\SOLIDWORKS\SOLIDWORKS 2017\whatsnew\import_export\Round Cover Plate_2.ipt.
- Make changes to the part using SOLIDWORKS features.
- Update the part with the second version of the part.
Any modifications you made to the base part are updated in the SOLIDWORKS part without losing the downstream features.
