Crash with referencing other part

Postby sjgallagher2 » Tue May 01, 2018 3:26 pm

FreeCAD 0.17 (full info below) crashes when creating a sketch in one part using a reference plane in another part.
Steps for reproduction:
  1. Open FreeCAD
  2. Create two parts
    Part and Part001 by default
  3. Make a new body in Part
    Make Part active and make new body
  4. Create a datum plane
    Show the object origin and use e.g. XY-Plane, offset by 20 units in Z just because
  5. Make Part001 active, make a new body in it
  6. Create a new sketch for this body
  7. Use Allow external features > From other parts or free features
  8. Select the datum plane
    Keep option for reference as Make independent copy (Recommended)
  9. Click Okay, FreeCAD crashes

It would help to provide a backtrace. Debugging

I don't see a crash on Windows, because errors are typically trapped rather than allowed to cause a crash, but the creation of the sketch fails. The only message in the Report view panel is,

App::DocumentObject has no view provider specified

I hope it'll be possible to use references from one body to an other one in a close future ?

Fixed with git commit dc46910231d

The problem was the use of "getClassTypeId()" instead of "getTypeId()" because it then created a new object of type "App::DocumentObject" instead of "PartDesign::Plane" and thus the cast to a Part::Datum returned an invalid object and assigning the shape the led to the segfault.

Thanks for your action, now it's well working on Freecad 18. But can we expect the same with Freecad 17 ?
