Attract Brush Issues

liamslegoclub — Fri, 29 Mar 2024 21:55:01 GMT

Hello Everyone, I've been hopping forum post to forum post, youtube video to youtube video, and I still seem to be stuck. I have a file that I'm trying to use the attract brush with to solidify the inside, and connect it to a base. Whenever I use the brush it is deforming the top of the original file, posts I read said to toggle off "volumetric", but doing that seems to make no difference. Thank you in advance to anyone who can help me solve this!!

The inside of your model is solid/watertight. So you may be a bit confused on the correct terminology of what you want accomplished.

But either way you can set the brush to NOT affect an area of a different facegroup.

Generate a single facegroup for an area you are okay with being modified, and another for one you do NOT want modified. Then under your brush set your filter to "Restrict to Groups".

I can only select one side of the model without having to flip the normals, would that effect this, because I seem to still be getting the same result of the model being deformed

What I said works. You may need to remesh higher first. Or else I'll need a video of what you are trying to do or at least the .mix

Yeah sorry I'm pretty new to the program, I thought this would be an easy fix (and it probably is) I've just been stumped with it. I've attached 2 screenshots along with the .mix file. I'm attempting to just fill the space between the map and the base, because when i split it up into pieces to print it doesn't allow me to because it's hollow.

Thank you so much for your help!

ok I think I may have rooted the problem, the underneath of the mesh isn't being included in the groups, would that have something to do with it?

So this task has nothing to do with the "GTA_V_Whole.stl" file in your original post? Why did you attach that file if your issue is with the map? Your map is not a model that was design with 3D printing in mind. It is just a open surface game model. It is extremely non-manifold. I'm guessing this your first 3D printing project?

Anyways, first thing you should do it just lower the map into the base, and if you are okay with that amount of stuff getting cut off, see if your slicer can run that. 'Attract' is not the correct work flow. Will not be detailed enough.

No that is the correct file, and not my first project either. I printed it scaled down drastically so it would fit on the build plate, and it went off without a hitch, I am now cutting it into 6x6in pieces to print it and connect it at it's original scale, which in total will be roughly 4x3 feet. I only have it elevated off the base so that you could see the hollow interior. If the attract tool is not the answer, is there any way I could fill in that area beneath it?
