New tool to add and subtract prismatic volumes #75913

New Issue

Status:
b79a5bdd5a implemented a new tool "Extrude, Dissolve and Intersect" (now Extrude Manifold) that performs the following sequence of actions:

extrudes,
dissolves the edges whose faces are coplanar and
intersects the new edges with the existing geometry.

But while useful, it would be interesting if this tool also supports:

A boolean-like operation by subtracting internal geometry.
Display result in real time.

Therefore, the purpose of this task is to developing a new tool that can replace the "Extrude Manifold"

Use cases:

Facilitate the creation of holes in meshes with volume. This is common for doors and windows for example.

Design:

New tool that will be located between the existing extrusion tools.
Since Boolean operations are CPU intensive, the boolean operation will not be modal, but a preview should indicate the volume that will be added or subtracted (similar to what is done in other tools such as loopcut).

Work plan

Time estimate: 2 weeks

- Operator
- Interface drawing
- Gizmo

HI, this tool is still relevant ? the current extrude manifold isn't really good I dont understand why they didn't keep destroy end optional, it doesn't make sense.

hey! thanks for this task but this doesn't look like it has made it to 2.91? since blender is in Bcon3; unless changing a whole tool is considered bugfixing i'd like to know if it is being developed still? I assume this will benefit from the new boolean code, can't wait!

@AnityEx Just add yourself as a subscriber to this task and you will get an email any time there's an update. A task is more like a proposal, it doesn't mean anyone is actually working on it at the moment, and this is a large one. I agree it would be very cool though.

Can this be ready for 2.91? I've seen Estimated Time: 2 weeks for a while now. but i don't really understand what it means :/

The estimated time of 2 weeks starts from the beginning of the work.
The idea really was to develop this tool for blender 2.91, but I was unable to schedule my time this month to work on it.
Depending on how to prioritize other tasks (like #81864 for example), this project can be anticipated.

This was supposed to be the solution to manifold extrude, what's the status on this?

It's a very useful tool in general and as requested as criticised, the critics go to the manifold extrude which is not working fine, in it's current state it's barely useful.

Status can be seen in patches D12421: Edit Mesh: Extrude Boolean Tool and D12698: Boolean Fast Mode Refactor.
D12698: Boolean Fast Mode Refactor needs testing and benchmarking.
