Canvas shifting when editing the feature

mah6786 — Fri, 08 May 2020 04:34:06 GMT

I encountered a strange behavior when I'm editing a canvas, the imported image shifts a bit when I start editing, and shifts back when its done. So I can never line up my image to my sketch because it keeps on jumping. How do I fix this?

Can you share a link to the design?

What you want is possible. The usual workflow is to place the canvas, and then sketch after. The sketch tends to refer to the canvas, not the other way around. But it's not obvious from your video what exactly your intent is. Glad to help but I need to test your actual design.

Hi Phil,

I am able to place the image canvas--the brown textured area is the canvas. The issue I'm trying to highlight is that when I'm editing the canvas, I have carefully aligned the corner of the image to the corner of the extrude feature . However, once I exit the canvas edit mode, the image jumps a little bit, resulting in misalignment. (See the screencast.)

I was eventually able to work around this issue by placing a construction plane on the face, and then placing my canvas on the construction plane. I also tried to recreate the issue in a new model with a simple cube, and it didn't happen. So it's probably some corner case bug in my model. Unfortunately I no longer have the bugged canvas in my model--I had to keep on working to stay on schedule.

The workplane is a more stable reference. Glad you found that. Thanks!

Hi Phil,

I encountered the issue again, this time I saved it as a separate file. The canvas in question is at the very end, if you look closely, you can see it shift when you enter/exit edit mode.

Thanks, glad to look. I'll probably get back to you Monday about this, if nobody answers in the meantime. Thanks for putting that together and sharing.

Thanks I can repeat the issue using your design. I also see that the decal sitting on a work plane does not move. So at least you have a good way to keep working on this.

Just curious, is your intent for the canvas to continue modeling based on the image? Or is it just for visual reference?

The intent is to base the model on the image.

Same problem is happening to me. Crazy -- makes it impossible to get anything done.

Have you tried the workaround mentioned above by @mah6786 ?

"I was eventually able to work around this issue by placing a construction plane on the face, and then placing my canvas on the construction plane."

If you could provide another example file I'll add it to the report for this issue.
