Every time I must copy a set of objects from an AutoCAD drawing to an Inventor part, I work diligently to reduce the number of objects. This time, DBCOUNT command reveals there are just 857 AutoCAD objects - lines, circles, arcs - being copied to the sketch.
Still, Inventor struggles to handle this very simple sketch
- when rotating
- when moving
- when indentifying closed boundaries for extrude commands.
Are there any strategies anyone has found to make Inventor more ligth on its feet when dealing with sketches brought in from Pasted AutoCAD objects?
Solved! Go to Solution.
First thing I would do is turn it into an Inventor Sketch Block.
THanks JD - that made it quick to move and rotate.
But, it still struggles for about a minute to identify the boundaries. Still, any improvement is greatly welcome!! Thank you.
Well, I would consider that to be a very complex sketch for Inventor (I recommend 7-10 entities max per sketch).
It looks like a lot of repeated sketch geometry (I recommend using feature patterns rather than sketch patterns).
Maybe lock down the sketch block, and then create new sketches and Project Geometry as needed from the sketch block.
(or get rid of repeated geometry, might break up into several sketch blocks and repeat blocks instead)
I'll grant you that it's got a lot of objects, but - just as you can defer updates in the model environment - it might be helpful to have a "define boundary" manual mode (ala MDT) instead, so Inventor wouldn't have to chug through all the objects and suggest all closed loops. I'm sure there are complications with this workflow and they've probably already looked at this. Thanks for the thoughts on this JD.
I think your best bet is to Project Geometry as needed to new sketches using the imported only as a master sketch.
