As usual I have modeled myself into a weird place. I have a micro line that will not go away and I cannot boolean out. This line is 0 x 0.0001 x 49.5. I tried deleting the face and then the line but that did not work. I tried a boolean diff of that side with 1mm in to remove the line (then I would add the 1mm back) but boolean fails. If you do a boolean union on the whole side it just converts to surfaces.

Yes, I am using MOI to create parts. Yes I know I shouldn't do that. I just like to work in MOI.

Ok I fixed my own problem. Instead of a full side boolean I made a box around the weird line and just did a boolean diff on that part (see yellow box where I did it), then extruded it back out and the line was gone.

Hi,

Why do you think you should not use MOI for creating parts?

I did my most recent 3D printer design entirely in MOI.

Hello,

The Align command is your friend. Whether you're using additive and/or subtractive workflows, using this useful feature in MoI can prevent you from having these sort of issues when building your model.

Hi Charlie, so that line is a little tiny slivery shelf surface:



When it's deleted the surface above it will still have a little edge in it that used to attach to it, that's why it was kind of hard to get rid of it.

At some point I think I might be able to automatically collapse such things when they are initially created, but that kind of automatic geometry modification is a pretty delicate thing, it's pretty easy for it to end up modifying things that were supposed to be there.

@OSTexo - Yep, I probably use the Align features more than any other tool.

@fcwilt - Agree. I use MoI for designing metal frame fixtures & small CNC machines, as well as 3D printed parts that depend on accuracy.

Glad I'm not the only one creating mechanical parts. I think, though, even Michael might say MOI isn't the right program. Fusion 360 is probably the right one, but I kind of hate it.

Hi Charlie,

You're certainly not the only one using MoI to create parts! I find the combination of its precision, elegant UI and extensible scripting make it a delightful tool to work with. MoI is my primary tool for problem solving, design and creation of construction plans.
