Wrong Dimensions of SVG

[Anonymous]

Hey!

I read all previous threads about this... but I am still unable to solve this.

This is the design I want to edit: https://www.thingiverse.com/thing:2850680 for 3D printing. I am not able to get the correct dimensions. I tried as someone said to import to Affinity Designer and change DPI to 96 ...but it made it only worse. 

How can I get the correct dimensions inside Fusion 360? The correct Dimensions should be around 100 mm x 55 mm and I get 75.009 x 41.911 mm when I import the original file from the link above. Can somebody help me to work this out?

This is pretty simple in Fusion, divide 55mm by 41.989374 mm and scale by that factor(1.309854391822698109522879583895) on the sketch using the origin as your base scale point. It should scale the object to be that value. 

Its very important to note when importing geometry created by others you may have to adjust it - more often than not.

To be honest this solution is no good. I want to have it exact.

There really isn't another solution that doesn't involve third party programs, even inserting this file into AutoCAD produces different results altogether and cleanup is still needed. You can add as many decimal places as you need to make it exact when scaling thats why the scale factor is so outrageously long.

An SVG's accuracy and quality will very heavily depending on where it came from - this really goes for most CAD formats, files and programs - but typically svg's I see going into Fusion are on the lower side of it.

Just no. Every program in the world can import svg with correct dimension. Please talk to the development department about this. I find 360 is unusable but so is every other tool out there - that is your plus.

Hi Peter,

because I was interested, I tried.
Since I don't know or have all programs available, I tested with Inkscape, Gravit Designer, Vectric V-Carve and Q-CAD.
Only Q-CAD delivered a result (about 100x55).
Inkscape and Vectric were with approx. 75 / 80 x 42 / 44
Gravit: 345 x193
Perhaps you can name some (known) programs that also provide correct results across applications.

For me QCad only came close because it has options for DPI on import, setting to 72dpi gives 100x55.985 so 1mm out on the 55mm dimension you specify. If the part needs scaling differently X and Y your circles will not end up round.

If I type 100/75.009 into the scale dialog Fusion scales it to the same size as QCad.

Rhino gave 283.5x158.7, so another CAD program that doesn't use the correct dpi.
