Inserting .SVG files from Inkscape to Fusion 360

I have been having problems inserting SVG files that I drew in Inkscape to Fusion 360. They are scaled wrong. They have always been really small, I figured out that I need to change the scale to 100% that helps, but not correct. It has never really mattered because it’s always been some sort of yard art, so I just scale it up to something close to what I want and go for it.

That all being said how do you do it correctly? This morning I drew a 6" square in Inkscape.

Then went to Fusion 360 and inserted the drawing, selected 100% for scaling and it ends up at 6.24". I must be doing something wrong, I’m just not sure what it is.

Just to clarify, it’s usefully yard art or a sign so it’s not that big of deal. If I’m making brackets or designing say a belt grinder I will use Fusion 360. I would just like to know how to scale things properly from Inkscape to Fusion 360.

And for Jim, as he always asks… LOL

It could be a DPI setting issue. SVG files are scaled in Dots Per Inch. There are several standards, but the most common current ones are 90 and 96 DPI. If you open one that is saved at 96 with a program that is set to 90, it will be larger than designed.

It could also be the stroke width in Inkscape. I forget how it is calculated, but the width of the stroke affects the cut line vs the displayed dimension in Inkscape. I set mine to the minimum stroke width on anything with critical dimensions.

If the SVG is an incorrect size when imported into Fusion you could always turn on the preference resized based on first dimension. Check out this topic for how that’s done.

It’s 92 and 96 which is almost exactly the error he’s getting. Multiply by 92/96 = 0.95833333

Apparently Autodesk has no interest in correcting this as it has been a problem for as long as I’ve used Fusion.

And if you start mixing metric and imperial designs, you’ll need to learn:3.937 x 92/96 = 3.772958333…

I was just going from memory, which is apparently faulty. You can change the default dpi setting in Inkscape.

Sure, and screw up compatibility with most other programs that import SVGs…

Fusion is the culprit here.

I appreciate all your input, and it led me to the correct answer. The one thing that has been bugging me is that I could import a DXF and the size would be correct, but not SVGs.

So, What I found out was that when importing an SVG into Fusion, when the dialog box pops up enter 96 in the Scale Plane XY field. And the imported deminison is correct.

Why is your imported SVG all black lines? Typically when imported they’re green locked lines.

I would suggest trying the resizing to first dimension suggestion. Where is you can control the svgs you produce you’re going to be pulling ones off the internet that you may want to make a particular size, easily.

You would have to unlock the SVG from the green locked lines to the blue standard undefined sketch lines.

It must be the way I did the screenshot, they are green.

OK, I got it. I just tried it on a Quail yard art. Thanks for the pro tip!

That’s a lot easier then going back to Inkscape resizing it.
