Trouble with imported sketch geometry

Anonymous

I've been working on making a mold out of a piece of fairly simple line art from Illustrator.  I've sort of got it working, but it's been a somewhat frustrating day.  

 

Here are some of the things I ran into:

 

  • SVG imports at 1 unit in SVG (pt from illustrator) = 1 unit in Fusion (inches);.  It's of course possible to scale using the dialog, but, because the units were so far off, the bounding box preview was invisible (all edges were off-screen).  That is: it was hard to tell that anything imported at all.  Suggest making bounding box shaded or something.
  • Sketch curve selection misses short curve segments.  It seems like this might be related to level of detail?  Basically, lasso/rectangle selecting around a mixture of long and very short segments misses the short segments.  This is a really, really bad bug, because it's really hard to tell what's going on unless you zoom way in and discover that some tiny segments are not getting moved/patterened, etc.  The result I kept getting was that the patterned sketch geometry wouldn't close and it took a long time to figure out that these short segments were to blame.  I cleaned up the line art in illustrator alot, but it's not totally possible to avoid these.
  • Some sketch curve segments are not selectable when in the move dialog.  I'm blocked here.  I cannot select these curve segments, even when very zoomed in:

The points and segments around are selectable:

These segments are selectable normally (when not in move tool):

  • Performance with these imported sketches is really bad.  I also did a rectangular pattern, which also seems to have really bad performance.  With the imported sketch ("Sketch6") enabled, display update slows to seconds per frame and is basically unusable.  Also, lots of flashy behavior around mouse-overs taking a second or so to update.  I've tried disabling effects, etc, but doesn't seem to help.

 

Here's the file:  http://a360.co/1JdBlxa

Any suggestions would be appreciated!

I do work with imported sketches a lot and I have same expirence. I always scale sketch before importing in to Fusion. This allow me to do that precisely. I also want to discourage everyone to use Corel, it never worked for me, never ( https://screencast.autodesk.com/main/details/3b2306be-58ca-47d2-8a87-c3060da599ce  those things happens only with Corels exports).

For troubles with selecting sketches I use selection filters. I always have "Select Through", with that when I do window selection it marks all, even the smallest curves. Of course I have to hide other objects in "view" or use other filters. I don't have idea what to do with last point, I've never run in to this, but I will check your file and see.

I've checked and every seams to be fine, just check "Select Through". For slow performance, maybe try to pattern feature (extrude/cut) in body instead pattern sketch?

Yes, the "small sketch curve selection" problem is one that we know about and are working on a fix for.  We hope to have it fixed soon.

 

The internal bug number, just for everyone's information is:  UP-16825.

 

Thanks for reporting this.
