Can't constrain arc in sketch

[Joel_graff]

Maybe we are doing different things...

Ok, so it seems there's some inconsistency in it.

When I tried the sketch, I couldn't apply anything without getting the error. I started a new document, rebuilt the alignment, and had the same result.

So, I decided to record it and do it again. This time, it worked just fine... until I tried to go in and change values to applied constraints.

See the video for details.

No. You should be getting the error with what you're doing. Can you apply angle and radius constraints?

I really have no idea at this point. It eventually fails, though I know in past attempts I have gotten a few constraints to apply before it starts giving me the error

I can apply angle constraints. But afterwards I can not change the angle value. This I can and will debug.

The other constraints I can change the value afterwards, radii and length:

EDIT: And I have the problems with angle constraints when drawing the range of dimensions in the international system. I do not think it is US/Imperial related. But it appears to be the size of it. The same geometry with dimensions in the orders of mm works just fine.

Note that when it comes to units. Locale can play a role (things like decimal separator). Therefore if you two are getting different results, when trying to follow the same procedure, it might be worth a try:

Code: Select all

export LANG=C
export LC_ALL=C
freecad

To see if the results are the same after.

I'll give it a shot the next chance I get. I really think it has to do with magnitudes and the order of construction that determines when constraints get borked.

Incidentally, I fixed the video link in my previous post. No idea what happened with the first attempt...

That's at least a consistent problem I've seen as well.

I think the other issues are demonstrable, too... In any case, whatever is causing the problem with the angle constraints is likely also causing the problems I've experienced with the other constraints, so debugging the angle constraint issue may fix everything...
