Hello Vectric experts and enthusiasts, and Happy New Year.....
I have two 3d components where one crosses over the other. Traditionally, I would have fiddled with modeling a shim to go under one part to lift it up over the other part which is being crossed over. But I thought certainly that there must be a better way to do this, using the "Extrude/Weave" function. So I reviewed the Extrude/Weave tutorial, and at the 48 minute mark, it shows using one 3d component (a paint brush) and stretching that over two crossing drive rails. During set-up, one copy of the model can be thinned and the other copy thickened at the cross-over point, to give a natural looking "weave" of this one part, applied in two places.
However, I have two different 3d components that I'd like to "weave"/(have one cross over, the other go under), which is not what is shown in the tutorial. These two parts are shown in the attachment, along with their two drive rails. Well, I thought I'd experiment, but all I get is a horrific mess.
Before I give up and just make shims to get one part to pass over the other, I thought I would ask the Aspire experts if there is in fact some way that I can use the extrude/weave command to manipulate these two parts to make a nice crossing-over/weave/bridge. It does seem like it would be a good thing to be able to weave/bridge two different parts using the extrude/weave command............. but wishing "don't make it so".
Thanks, Chuck

Re: Weaving two different models
Hello everyone.... Here is what I wanted to achieve using the weave function, but I had to do it with a shim.
Using shims, I had to make several shims and experiment around to see if it looked right,,,,,, When it didn't look right, well, I'd go back and make a different shim. A pokey trial and error process, at least for me. That seems far less cool than being able to use the weave function with its adjustability.
If someone knows how the weave function could be applied to this/similar situations, I'd still like to know how. Thanks, Chuck

Re: Weaving two different models
Chuck,
How ever you had to go about creating the weave it looks great. I hope to one day be able to accomplish such models....

Re: Weaving two different models
Hello John. Here is how I made the one vine cross over the underlying branch. The first picture shows what I had to start with, the crossing vine wasn't high enough. (And tilting/fading options were simple to apply to make the vine cross over the branch, but it looked very in-natural. You want to try and just naturally lift up the vine where it would cross the branch. Sometimes things are so far off, you can't even use tilt and fades at all....)
Since the vine was made with a two rail sweep, I made the shim with the same pair of drive rails, but used cross sections that were simple open bottom rectangles, going in height from almost zero to the maximum of what I determined was needed to get the correct "lift". That final shim is shown in the next picture.
But the shim by itself doesn't work, as it interacts with the vine and the branch you want to cross over. (I almost included some pictures to show the wrong junk you get if you don't move the shim and vine to a new/separate level, but thought that may confuse things....) So I moved the shim and the vine to a new/separate level (Level 1 as shown in the next picture). There they can be adjusted without interacting with the branch I am trying to cross over. When the shim and the vine work together the way you want, "Bake" them together. Then move them back (just for logical organizational purposes) to the level where all the other related parts of the assembly reside. The final result is pictured............
This method is a bit cumbersome and slow to make readjustments, which is why I was interested using the weave tool, to make quick adjustments.....
I hope this makes sense............ Chuck

Re: Weaving two different models
Chuck,
Thanks for sharing your technique. When I saw you post I try figuring it out. I got the wedge part although I didn't make it long enough. I didn't move the components to a separate level (that was my big mistake) I did turn off the other vine and used Create component from visible model then unchecked the original components.
I was using extrude instead of the two rail sweep. I got close, but it needed more work
Thanks again for sharing....

Re: Weaving two different models
You are welcome John. No doubt you can see why it would be nice to have the weave tool be able to handle these types of tasks.......... Chuck

I can, it would be a great add to the component settings.

The "Lily Leaf Molding" tutorial covers this topic also.
