Calibrating a canvas?

awelton00 — Sun, 24 Oct 2021 01:17:11 GMT

I used the calibrate canvas function extensively in F360, but I can't seem to find a way to accurately scale a picture in inventor. I have been googling for an hour have not found anything aside from scaling from the original size by a factor, which is not what I'm looking to do. Is there a way to calibrate a canvas in inventor from point to point without trial and error?

What's a canvas?

Are you using an image as a background to a sketch?

Yes. In Fusion 360 an inserted image is called a canvas and there is a dedicated function to calibrate it. That video does provide what I am looking do to, however convoluted. Thank you!

@awelton00 @swalton
That was way too much work.

Attach your file here for demonstration of the easy way to Calibrate an image (that is better than Fusion 360).

Sure. Here is a pretty typical example of a sheet I receive, except they were nice enough to fully dimension this one. Usually I just get an overall length and have to trace the rest at scale.

In the video I forgot to mention that you can turn off the Dimension Visibility after calibration of the image.

Ah, thank you! I'm surprised I didn't think to try that, as that is the way I used to have to do it in OnShape. I appreciate you taking the time to record this.
