Can't move sketch elements to where I want them.

This is infuriating. I've copied the profile of a hinge from one part, and I want to add it to another part. All the sketch entities are properly related to each other, but I absolutely cannot place them against the edge where I want to extrude the hinge.

If I make a line collinear with an edge, the sketch becomes overdefined.
If I make an endpoint of the line coincident with the edge (thinking maybe the line and the edge aren't perfectly parallel?), the sketch becomes overdefined.
If I dimension the gap between the edge and the line, there's no problem. But if I try to change that dimension, the sketch becomes overdefined.

This is ridiculous! It should be perfectly straightforward to place the sketch elements where I want them. Shouldn't it? I am so sick of these asinine bugs in Solidworks, and so looking forward to retirement (less than a year!) when I won't have to deal with this garbage any more.

For what it's worth, I'm using SW2014 SP5.0. Any ideas? Thanks.

Correct Answer

Apply the relation you need, even though you get the sketch overdefined

Then just run the SketchXpert and eliminate the offending relation.

Alternative - post the file here.

OK, that solved it. "SketchXpert" found and deleted a perpendicular relation. But there was nothing wrong with my sketch! That relation had nothing to do with the problem. I've been using Solidworks for 18 years, and I'm pretty sure I am a sketch expert.

This is a crock of ... never mind.

Thank you.

You made me curious. I would really like to play with your file.

Sorry, I've moved ahead with my design. I tried just now to go back with a copy of the part, but I can't recreate the problem.

Is it a Bug Max or did you just copy more than what you think you should have copied in the sketch?

It looks to me on the outside that the 0.500 horizontal dimension should have been deleted and it would have moved over as you wanted.

Steve, I don't see how that would affect anything. The .500 dimension is just between two blue lines, and controls the shape of the hinge.

I did try dimensioning to the frame member where I wanted to place the hinge, but I couldn't edit that dimension without blowing up the sketch.

The solution, found by "SketchXpert" (grrrr), was to delete a perpendicular relation between two lines on the outboard leg of the hinge. I honestly believe it's a bug.

FYI, I just had the same problem. I could not move the sketch to where I wanted it. BUT in my case it was because SWX limits the size of the units. Designing anything BIG in SolidWorks is STRICT VERBOTEN!

In this case, I am representing a mound of tailings that amounts to 31,000,000 cubic yards. This is because our senile governor Brown has an idiotic plan to build two, fifty-some foot diameter, thirty mile long tunnels through the Sacramento Delta to help provide water to Southern California. Their plan has no accounting for the immense scale of tailings from the tunneling.

SolidWorks, please tell us why we can't design things on a grand scale. It' just numbers after all. AutoCAD can do it. Are we not allowed to do any civil engineering or anything on an astronomical scale? WHY?????????????????????????????????????????????
