Objects disappear when using the Union Boolean

[b.l.rutlidge]

Objects disappear when using the Union Boolean. I have tied deleting history, cleanups, clean geometry and nothing seems to be working. I attached a file that is doing the same thing as I'm my real project. The problem could be the brick wall not being one solid mesh, but I don't know how to combine all the bricks into one clean mesh if there is an option for that.

Please help...

Your cylindrical pipe is not one object it is a bunch of combined cubes. I think Maya does not like that geometry.  If you take a poly pipe and 3 cubes, and do the bool... it works. Yes those combined cubes is the problem.

Instead of cubes use Poly-pipe and add some more edges to your need. Maya Boolean tool was not so great, how ever , it has improved a little bit recently like 2016.

Is there a way i can combine the cubes so that they are one object. The brickwork matches my original scene and I need these shapes cutting into it to creat long windows.

Use normal or displacement map to get the desire bricks pattern instead.

Can you show me

I will get back to you with some demo some time today

Sorry, I was supper busy yesterday. I would like to know what exactly you are trying to achieve? Looking at your scene, and you were trying to use Boolean >Union , that command only attaches as one object. If that is what you want then you can simply combine them or group them together.      2:  If you are trying to carve out holes using those 3 objects then you can use Multicut tool or projecting curve to cut the brick wall. A bit more information will help me to narrow down to an alt approach.

Its ok I've sorted it now 🙂

Awesome. keep up hard work man. Getting use to Maya takes time.
