FreeCAD hangs when using Draft Dimension

Post by drei »

Hello,
I would like for someone to confirm the following behavior before I file a bug report.

Opening the attached file, you can see that I have several objects projected into the XY plane.

When I try to create a Draft dimension between the origin and one of the lateral objects, FreeCAD just hangs forever in time.

Steps to reproduce:
  • Start FreeCAD
  • Open the file
  • Load the Draft Workbench
  • Set the Workplane to XY
  • Select the Dimension Tool
  • Two ways to trigger:
    1. Select the origin and then try to select a point from a lateral object
    2. Move the cursor to a point over the lateral object


Unfortunately, due to the freeze I'm forced to kill the process so gdb is unable to present any info when using bt.
Here's the complete output

I am not seeing ay such behavior with your file here. Though my development version is a few commits ahead of yours. Don't see the problem with 0.15 release version either.

Thanks Mark,
hmmm...
Perhaps I messed up bad in something, I also noticed that sometimes it outputs something on the lines of Invalid BSpline. I'll keep testing to see if I find anything.

I don't think it's a hardware problem, my specs aren't that bad:

Code: Select all

                  .o+`                 isaac@Arch

Re: FreeCAD hangs when using Draft Dimension

I have no idea why this happens then.

I have a recording about how to reproduce the error
http://youtu.be/NcG08wg1etg

I'll file the issue in a minute since it just seems really weird that this happens. Also is this considered a crash or just a bug?

Just updated and there seems to be no change in the software as Mark already mentioned.

Ok, I got it too,
To repeat the problem I have to enable all the snap tool buttons. It take more time to you on my computer but I get the same freeze.
@drei : Can we see what Snap buttons are enable ?
I repeat the operation and it seem that it's the Intersection snap tool that cause the freeze.
Edit : well, I'm pretty sure it's it. I have only enable the Intersection snap tool button and FreeCAD freeze even to pick the first point of a dimension or a line...

Well, indeed all snap tool are enable except one. Try to disable intersection tool and let us know if you still can freeze FreeCAD.

It really is weird, running a single Snap Draft option at a time doesn't cause a freeze.

I built a Debug version of FreeCAD and got the freeze again,

Here's the gdb output, again no bt info available since I have to kill the process:
