Is the problem only for the draft feature?

[leoheck]

Sketch works, another feature of the design, works as well.

[leoheck]

I will check this later with a smaller file, cool?

[leoheck]

The same still applies, unless I am doing something wrong. lala.FCStd.zip

This is still happening.

Datum line was selected as Pull Direction.

Also, I cannot select and use Z-Axis directly instead. WHY?

Also, the name Datumline means what? It should have at least a label there, since any dadum line will appear as Datumline

I need steps to recreate. I only manage to see:

1. Create a Body
2. Create a Sketch with a Shape lets say a circle.
3. Pad it.
4. Select the vertical face (the side of the created cylinder)
5. Use the PartDesign Draft tool
6. Select the neutral plane (the top or bottom of the cylinder)
7. For the pull direction, select Z-Axis (no you can't)
8. Create a DadumLine using the Z-Axis as reference (rename it to My_Datum_Line)
9. Edit the Draft feature again.
10. For the pull direction, use the My_Datum_Line
11. Check the Report View.

In other words, I can only use the Features of the Design as Pull direction.
