How do I create a sketch entity from an in-context part?

brian_wood

I have an RS-232 connector from my main assembly poking through a rear panel part. I am editing that rear panel part in-context (thank you, by the way), and want to select the outline of the RS-232 connector and then grow it a little for clearance, rather than drawing an all new set of lines and curves. How?

Hi @brian_wood

You should be able to bring in-context entities into a sketch just like normal geometry using the 'Use' sketch tool:

As for the growing step, you could try the 'Offset' tool:

Hope this helps!

I figured the offset tool would work. Tried the Use tool but had trouble. Will try it again and see if I can get it to work.

Yes, Use and Offset did the trick! Painfully slow tonight - even the rendering is showing line segments instead of circles - but it works. Busy servers, perhaps? Of course, I am also streaming audio and only have a 10MB bits/sec download and 0.8 up. Sheesh. Thanks for the help.

If you are experiencing poor performance please submit a support ticket using the "Feedback" option under the "?" menu of your Part Studio. 

It sounds like the assembly context you're looking at may be particularly complicated.  Do the issues you're seeing improve if you switch the context to "None"?  The line segments you're seeing don't have to do with your internet quality, they may have to do with a large amount of graphical entities that are being displayed in the studio or they may be showing up because your arcs have a very large radius.  We always strive to improve our tessellation quality, so submitting a ticket will be a useful case for us to investigate.

Slow internet could cause laggy regeneration after edits are made to features, but laggy regeneration could also be due to a very complicated set of features in the Part Studio.  You can check if the issue is the complexity of your features by pressing the stopwatch next to the feature list:
