Splines

Hello,

I have created a DXF file which contains a top view of a ship.
I can open the file in 3.4.5.0 without any problems.
In version 3.21.3.0 the splines are corrupt.

If I save the file in Version 3.4.5.0 in DXF R24 or R27, the problem is the same.
Does anyone has an idea why it happen?

Kind regards
Matthias

Looks like the spline start / end tangents are not correct.

Try this:
1. Select > Select all
2. Misc > Modify > Reset Spline Tangents

If you can't solve it, attach the file please.

I hit the same problem going from 3.15.5 to 3.22.0. The same correction worked for me.

Attached is the dxf before the correction in case that is useful to see where the odd tangents originated. I don't recall having selected tangents in the first place, and the property editor does not allow turning off using tangents.
