Projecting sketch lines onto a multi-faceted surface

lalkAGGCF — Sun, 14 Mar 2021 06:18:04 GMT

Hi all,

I'd like to be able to engrave distance markings at 1cm intervals on an organic surface. However, the organic surface is a BREP created from a complex t-spline, and therefore has many faces representing the surface. I tried to use the "project to surface" command, but it doesn't seem to work with more than one surface selected at a time.

Is there a better way to achieve a consistent depth line marking on this surface for engraving?

Thanks in advance for your help,

Lee

Can you Extrude as Surfaces and intersect?

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

Hi,

Thanks for the suggestion. I tried to upload, but the .f3d file is 70mb and isn't accepted by the forum.

If I extrude as surfaces and intersect, is there any way to limit the depth of the intersection to a consistent depth, say, 0.020" from the surface? Otherwise it seems it would result in a variable depth engraving.

Thanks again!

Hi,

Hoping someone can help with this. I thought about creating a second copy of the model and shrinking it by a small amount, then using the projected sketch to cut only the original body. That would leave the smaller body as the base of the cut. But, this seems like a very processor intensive way of doing it - it's already quite a complex model, and I suspect if I duplicate it my computer will balk...

(See Message #2 above.)

If it is too large, can you zip and Attach or make a public link?

Move the Timeline marker to Beginning.

Now export the file with the Timeline in this rolled back state.

Is the file now small enough to Attach here?

Hi,

I uploaded a zipped version to google drive - hopefully this link works:

Just bumping this thread, as it fell off the first couple of pages of the forum.

Hoping someone can take a look for me, thanks!

Do you need the large internal cavity? (Not referring to any features that extend to external "air".)

No, not at all. I actually didn't realize that was there - I thought I had filled it in

Is this what you are after?

Yes! Please let me know how you managed it! Thanks very much

Thank you!

For some reason, when I tried that before it gave me a different result - I ended up with only the areas that intersected remaining. I'll try it again with the options you show selected. Thanks again!
