Trying to Join Bodies

nmhinsch — Tue, 08 Oct 2024 21:54:57 GMT

I am creating a form to 3D print as a "bottle." I am trying to create one form, but I could not overlap the faces, so I made it into three bodies I wanted to join but could not because they are shells. So, I tried to stitch the surfaces together, but I was also not able to stitch the surfaces together. How can I turn these three bodies into one continuous form that could theoretically hold liquid?

Please share the model by attaching it to a post in in .f3d format

Ok, I attached it below.

Your model violated a number of recommended modeling practices for From (T-Spline) modeling.

1. You likely modeled this exclusively in smooth-view mode,. Have you looked at it in box-view mode? It looks very uneven and has self intersection geometry in several places.

2. There are triangles and many N-gons in the model. That seems particularly unnecessary in a simple model like this.

If you have a visual reference you are modeling this after, an image of video, then I can demonstrate how to model it.

This is the real-life model I am basing it on, but I am adding a sphere in the bottom empty space in the middle that I would like to intersect with the sides of the form.

Very nice! I t will take me a couple of days to get back to this. If you don't see a post from me, please tag me over the weekend.

The way I will likely pursue this is that I would create a few 3D fit-point splines (not more than4 spline points) and pull those into the approximate shape. Then use the T-Spline pipe command

This is what i have so far, but it means little without seeing how I modeled it. It just shows that this can be done 😉

You can see that all the tubular structures are interconnected in the T-Spline.

To answer your initial question, it is best to join the structures into one cohesive T-Spline and not afterward when they are converted into separate surface bodies. The video explains one way to approach to model this. It is almost 40 minutes long, so that shows that patience is needed.

But patience was likely also needed to create the clay model 😉

I the initial video I missed that this also did not convert. Here's the fix :

Thank you I will follow the video.
