Blocker BUG: Insert SVG file goes dead

[Anonymous]

Steps:

1. Create a new project in Fusion 360

2. Insert the SVG (see attachment)

3. Fusion 360 goes dead

But you can open this SVG file simply in a browser within 0.1sec.

Bug level: blocker (actually I met bugs causes crashing a few times every day, I only report the blocker level bug 😉

Repeatable: 100% (tried 3 times and crashing all times) 

Env：

- macOS 10.14.6

- Fusion 360 v2.0.8816

Have you done any research on Fusion and SVG file imports in the forums? There's plenty of info suggesting you should avoid SVG files with more than a few hundred curves, your file contains over 10,000! Worse than that of those 10,000+ curves ove 5,000 are duplicates!

That said, if you start a sketch and uncheck Show Profiles and Show Points the SVG will import after a few seconds but be warned, if you enable Show Profiles Fusion will look like it's crashed but will probably recover if you wait long enough. What do you actually want to do with the after import?

Hi Mark,

Thanks for share those tricks, I haven't notice them in forum. 

My plan is to create a flat fabric outline cut for a component surface, the SVG file is exported from Blender 2.8 UV unwrapping. I don't need those interval triangles, reducing the triangles is definitely doable if I know where the issue is. But just a bit curiosity: why 5K-10K vectors is so hard for Fusion 360 with a modern i7 CPU, if I remember correctly, it's an easy job for my father's ancient PC with 386 CPU 25 years ago.

Fusion's sketch environment has to calculate all the closed profiles, intersections etc. It's not dumb like you have in a illustration or CAD program without a sketch solver. CAD programs generally use one core so fast processors are more important than more cores and a 25 year old program running on a 386 couldn't do what Fusion does so not a good comparison. If you download one of the 2d AutoCAD programs like QCAD it will have no problem with this file but QCad is just a dumb 2d program.
