[Solved] Changing Angle Value Causes Unsolvable Sketch

Post by PAS_Drafter »

I'm trying to create a master sketch for an Assembly that controls a lever and the motion of the cylinder. I'm drawing up the Master sketch and trying to get the variables to work properly with the sketch, but I'm running into a problem when I change the angel value for 0 to 90. I get an unsolvable error. I've tried moving the reference angle to a number of places but no matter what I do, I seem to get the same thing.

If I start with a 90 degree angle on the lever

I can change it to 45 degrees with no problem

I can then change it to 0 degrees, again with no problem.

However, when I change it back to 90 degree I get the error

Anyone know how I can get around this or what I'm doing wrong?

Thanks

I got the same here when changing directly from 90° to 0°.
You did nothing wrong. You can add Advanced solver control in preferences and then check in Sketcher the Sketch size multiplier (or increase the number of iterations.
A Sketcher Lecture with in-depth information is available in English, auf Deutsch, en français, en español.

That solved that problem. Now my stupid Cylinders aren't staying on the right axis as I change degrees. :shock: I'll go back and look at the tutorials and see what I did wrong. I'm pretty sure it is just the way I'm linking them. I haven't done this for a while and I have to go back and remind myself.

Thanks for the help again.
