Fusion 360 is very slow

[Anonymous]

I can't modify my sketches when they start to be a little bit more complicated than a simple rectangle. In the sketch 14, I cannot trim anymore for example. can you help me? The logiciel is very slow. 

Thank you

the problem with this sketch is that it contains an error - the solve is failing.  That is why you cannot trim.  I tracked it down to the fact that the circles in the screencast below were constructed with a pattern.  If I delete the pattern, I can trim just fine.

By the way, there is usually no need to trim in Fusion - you can keep those circles as they are.  Or, instead of using circles, just create the tangent arcs between the lines, or use Sketch Fillet.  Lots of ways to do this.

screencast embedded.  I wish they would fix screencast embedding on the forum...

Hi,

the warning was caused by the missing direction in the pattern:
