Ultra slow performance

[goochman]

I have an Intel I7 8700K running at 4.9ghz, 32GB RAM, GTX 1080 GPU running Windows 10. My performance, typically after adding an SVG to a sketch is absolutely dog slow. It can literally take 10+ minutes to select some of the sketch elements to manipulate them in any way. I've currently been waiting almost 15 minutes to do a simple point to point move.  I know this can't be normal. Does anyone have any suggestions?

this sounds very model-specific.  How large is this SVG?  The Fusion sketching environment is not designed to handle thousands of points/curves in a sketch, which some SGVs contain.  You might be better off re-creating the design with fewer curves as native Fusion geometry.  If you want to share the SVG here, I can take a look at it.

sure thing, here it is! Thanks for the super fast response!

yeah, you are not going to have a pleasant experience with that as a Fusion sketch.  That SVG has got about 9000 lines/arcs/curves and 9000 points.  The Fusion sketcher does pretty well with a hundred items or so.  The reason is that Fusion is a constrained sketch environment - you can apply dimensions, constraints such as parallel/perpendicular/tangent, etc. to the sketch elements.  This is very different from an editor like Inkscape or Adobe Illustrator that just creates the curves and does not do any solving.  Plus, Fusion is trying to detect closed areas in the sketch, to allow you to Extrude them as solids.

The solution depends on what you want to do with these.  You indicate that you want to manipulate these elements in some way.  If so, then I would recommend just re-creating the geometry with Fusion native curves.  In the screencast below, I do a reasonable job of tracing over the "B" in 2 1/2 minutes.  If it is really taking you 15 mins plus to do a modification of this sketch, then you will no doubt save time by re-doing the curves.  A lot will depend on how closely you want to mimic the "bumpiness" of the existing geometry.  Personally, I would want things smoothed out a bit, and if you don't care too much how closely the match is, you can do a lot quickly.  The squiggly lines at the bottom would be the most challenging to do.

A couple of hints:

• turn off Profile display on your imported geometry - that will speed things up by itself
• when using the spline tool, hold down CTRL (CMD on Mac) to avoid lots of annoying inferences, including projecting geometry from the SVG sketch
• create a new sketch for the new geometry.  When you are done, just delete the old one.  Be careful, though, if you end up inferring any auto-projections from the SVG sketch, those will show up as errors in your new sketch

Because I'm home with a cold on a Friday afternoon, and avoiding real work, I spent 1/2 hour, finished the "BASIC" text, and re-did the "vanilla" part, just to prove I could.  Here it is attached.  It's not an exact copy, but it's pretty good, if I do say so...

[goochman]

I appreciate that you did that, but these are client logos so they need to be exact. recreating isn't really an option for me unfortunately

       We really need some kind of a solution for these things as I am also running into this more and more often, svg's  are slow mesh's are slow pretty much anything imported except a simple object is slow and painful to work with. It seems to be a bottleneck all the time, people spend big money to have things designed/sculpted. Or you grab an svg of something off the net nope has to be rebuilt. I wish someone who knew about this would chime in and tell us what a solution is other than rebuild because no one will pay for something to be done twice, and quite frankly im not spending hours rebuilding something that is perfectly fine, and should be drag and drop, (this isnt the 90's) in almost any other program.  1/2 hour to rebuild text that probably has a font for is absurd! Don't even get me started on the abysmal text tool in fusion. if you want to drill holes machine flat surfaces great but get into a 3d model or text or anything and it gets real hairy. Dont want to sound like a downer here but I feel like fusion 360 could be AMAZING but has missed the mark in so many ways.

Bumping this thread because this problem shouldn't still exist. I'm importing a 24KB .svg file to try and emboss onto a model.

Fusion 360 developers will chime in and say some nonsense about constrained sketch environments and Fusion 360 can't possibly be expected to handle more than 300 curves in 2021. Surely there is a workaround. Surely you can fix this problem.

This problem has been documented since 2014 in these very forums! How are you not able to solve this or create a workaround? What are you even doing about the problem?
