How to scale a DXF without a canvas?

karl — Thu, 07 Nov 2024 23:41:24 GMT

I'd like to import a DXF and scale it. All the tutorials I've found either address scaling images other than DXFs or importing DXFs without scaling them. The latter doesn't help me. The former tutorials show a canvas being created on import, but no canvas ins created when I import my DXF. If I try to create a canvas, Fusion asks me to import an image, but the dialog doesn't support DXFs. How should I proceed?

If you have a compatible DXF, one would expect it to be the right size, Insert it.

You will be asked which plane to put it on. A sketch will be created and the dxf articles will be added into it.

If the insert location is inconvenient,

Edit the Sketch, Select all, and Move Point to Point, allows for repositioning.

Might help...

Hi,

The whole point of a dxf is that it is a CAD drawing and as such is already scaled to the correct dimensions. If you need

the scale to be different then you should be doing it natively within the CAD program that created the original file. If

you don't do this then all of that information contained within the dxf becomes useless. It will no longer be accurate

because scaling will change the dimensions and there will be rounding errors and other problems.

SVG files are vector files and are different to dxf. They do not have any actual scaling measurements within the file.

This is why you can scale these type of files and other images. A dxf is not an image, it is a construction.

Cheers

I thought SVG stands for Scalable Vector Graphics, (same as a DXF) and not

raster graphics (pixelated images).

With no experience with Illustrator, does it save both types as SVG?

you have to be actively editing the sketch you placed the dxf in to scale it.

careful. imported sketch geometry (dxf and svg) is notorious for causing problems in fusion. since the dxf won't have any applied constraints, scaling it can compound the issues.

Hi,

Just went back and found an old dxf file I haven't used for a while.

If you edit the dxf like a sketch then you can use the scale command.

Might go wipe some more egg off my face again now.
