Issue with faces of sketch

Postby _WG_ » Wed Apr 19, 2017 7:04 pm

I have an issue with the Sketch001 that i want to use to make a pocket (see attached file).

Message: Failed to validate broken face

I'm not able to fix this issue. Maybe you can support me. I tried to make this Sketch multiple times and in small steps but always the same issue.

My FreeCad Version:
6703(Git)
2016/04/26 13.03.07


Thx.

Hi, welcome to the forum
As you can see in the inage I discovered 2 things in your sketch
1) A line is drawn rwice
2) A coincident point is missing

After correcting these problems the pocket operation will succed

Your FreeCAD is outdated. Please use 0.16.6707 or 0.16.6706 (depending on your OS). There have been some bugs fixed.

There was no issue here but it is better to have the version with less bugs which everyone else here uses.

Hi William,

i can not reproduce your findings within the Sketch. All lines are closed... 1 degree of freedom

Version 6707 2016/11/11

Thx.

If you want to connect two lines use a coincident constraint on the end points, don't use the point-on-line constraint. Even if the end points have exactly the same position, they are not connected.
BTW: point-on-line doesn't even mean that the point is on the visible line segment. The point can lie anywhere on the infinite projection of the line.
