Would it be possible to provide a sample file or steps to repeat?

Hi Tim I'll send you the file, but basically it's just gone mad. Worked fine up until a point and then started doing this.

Had it before where you click auto drag a box around the lines etc and they all collapse into on pile.

I'll send it later.

Ok thanks, will look at right away. It kind of looks like the coordinate system associated with the sketch is confused. Each constrained system has a local coordinate system.

Steps to repeat. Turn on work plane snaps. Draw a non horizontal line and stick a horizontal constraint on it. You'll see the 'slots' layer doesn't have any sketches. This is because it started going mad and I could do them.
Also you might be interested that task manager thinks it's viacad pro 9 and also when it crashes it says the same thing.

When we add a constraint, we would regenerate everything in the model flagged for regeneration.

If anything did not regenerate, it would undo/remove the constraint you are trying to add thinking it had invalidated the model.

Your model has two cover surfaces that are marked for regeneration but fail. I noticed that the failed covers do not have anything to do with the constraints you are adding.

So I've made two modifications that should help going forward.

1. If a previous covering operation fails on regeneration, it will now display an error dialog box at the time it occurs. Previously it did not.

2. When we add/update a constraint, we now only regenerate the applicable sketch system, and all entities dependent on that sketch. We no longer require the entire model be able to regenerate to add/update a constraint.


Still testing more cases, but this looks safe to make a 1442 build.

Tim

That should be fixed in the 1441 build. I'll double check with the guy who did that change.
