Solidifying a T-Junction

Currently there are no immediate solutions (that I can think of) to the 'variable width walls from edge-based mesh' problem, though it is interesting. There are however Offset Scripts that generate fa …

Boolean Modifier Red Won't Work or Behaves Strange

It's red because there's no object selected to Boolean with. When I picked the other Cube it worked fine. The "Cannot Execute Boolean" is because of this beauty: In this case the geometry was ob …

Unable to make holes using boolean modifier

The problem with your file is that you have a lot of disjoint geometry and non volume geometry. Observing a small section of the model shows a problem: A, B, and C are disjoint. (Not attached to each …

Cannot execute boolean operation for hexagonal mesh

Your torus grid layer consists of 5 disjoint grids. Those sections match up quite well with each-other to give the impression that they are joined, but topologically they intersect. The Boolean modif …

Why does the mirror modifier sometimes give me an overlapping mesh?

You can also add an Empty and place it where you would like the mirror to be, then set the mirror object variable to that empty. But keep in mind it is convenient to use the origin as a mirror point f …

Where can I find the code behind the Remesh Blocks modifier?

Blender Modifiers are not written in Python but are compiled into Blender and written mostly in C, therefore Remesh won't be found in the scripts folder. … Alternatively you can browse the source tree on-line figuring out the path should not be difficult, but here it is anyway: source/blender/modifiers/intern/MOD_remesh.c Questions about the C / C++ sources …

How to make a mesh surface that looks like cubes stacked in the shape of a sphere?

I think you are on the right track here, but the slowest part is the creation of all the primitives. (reason - each new object's name must be checked for name collisions, and this gets progressively s …

How do I create a property in a panel to edit particle systems?

It would be something like: particles = obj.modifiers.get("ParticleSystem 1") if particles: row = layout.row() row.prop(particles.particle_system.settings, "count") or particles = obj.part …

Python access to Skin Modifier data - again

The original question you link to mentions this in the first line, but doesn't make a point to clarify why the Object/Edit mode switch is important. Non BMesh When using obj.data.skin_vertices[0].da …

disappearing skin_vertices after assigning new mesh to object

This is a solution I use already, but it results in a lot of extra code to make sure other modifiers stay in the right place. … In viewer_skin.py (linked to) I am hardcoding the modifiers, but you should imagine that I don't want to make any assumptions about which modifiers are on that stack at all (except for the skin modifier …

How to apply a several modifiers with python (but not necessarily all modifiers)?

bpy.context.scene.objects.active = obj # this operator will 'work' or 'operate' on the active object we just set bpy.ops.object.modifier_apply(modifier="my_modifier_name") In the event that you want to apply a subset of modifiers … modifier in target_obj.modifiers: bpy.ops.object.modifier_apply(modifier=modifier.name) execute(None, bpy.context) This is one way to apply the modifier, there is also a direct way to apply all modifiers

How do I do a clean boolean?

The short answer: To get nice results with booleans on polygons you have to make the two entities have a similar level of division. If you can align the geometry for both entities then you will get mo …

Fixing a messy boolean operation

Then subdivide the plane (or flattened cube) first, and you will end up with (possibly) more appropriate geometry. If the surface is flat and you don't intend to deform it, it should not matter how …
