Celtic Knot Model Problem

Postby davemartin88 » Mon Sep 04, 2017 6:01 pm

Hi there, first time back working with Aspire after a long illness and trying to make a 3D component of a Celtic knot from a set of vectors. I had thought I would be able to use the "Create Shape" tool but no luck so far. Attached the file and hoping someone can give me a pointer. Just looking for a rounded shape following the vectors as drawn with the over and under pattern. Thanks in advance!

If you want the "Over and Under" look you'll need to use the Extrude and Weave tool..
Unfortunately that means you'll need to draw a single vector between the ones you already have.

Maybe the Offset vector tool can also help.

Thanks, will take a look at that tool. If I could get a component without the over and under, maybe I could use the sculpting tools to get the look?

Evidently some problems are more KNOTTY than others. . . . .

Could not resist, I will sit down now and chew on the cover of the book.

If you draw the vectors yourself, it's just one circle, four half circles, and a square and then the extrude and weave tool applied. I put each of the vector sets on different layers for illustration.

Will take a look at your file. I did draw the vectors myself but having trouble getting the right result with the weave tool, will figure it out. This one is a bit Knotty.

In addition, the extrude and weave tool has a default setting of 70/30 weave. That is easily adjusted for a stronger or weaker woven "look". Weaving, or not weaving is a single click on one box. I went nuts with weaves right after this tool was added to Aspire, and it's still my favorite tool.

Good progress on the knot this morning. Going to use it as part of a sign for a house that a friend of ours wants to display. Attached is the first preview, will be adding a border or something to enhance it a bit, the recipient is still thinking through whether they want a solid wood version (with letters highlighted) or a painted version. Will probably cut a sample in 1" insulation foam that could be painted. Thanks to all for the help!
