Help using a CAD program

[Tallbump]

I have seen some videos on Tinker CAD, looks pretty user friends.

But I can't quite figure it out

I bought a file of a cralwer body I want to use. It's a semit. The front is actually set up in 3 pieces. The hood (A), the driver's cab (B) and the sleeper cab (C)

I don't want to use the sleeper cab. But the middle section doesn't have a back wall as it is meant to open into the back section, which has a back wall.

I want to take the back off of C and attach it onto the rear of B.

I am guessing this shouldn't be very hard to do. I just can't figure out the controls in Tinker CAD

Are you getting this printed, or printing it yourself? If it’s being printed, you’ll probably want to print it in multiple pieces anyway to avoid of a ton of supports - could you use the slicer’s tools to hack the end off the sleeper cab and print it as a separate piece?

That back won't fit on the cab. It's bigger than the cab, as shown in your pics. You're going to have to model that yourself.

I will be printing it myself. I am not sure how to hack off ends. That is where I am struggling

The sleeper cab is taller, so it would need resized down some to fit the back of the cab. I was figuring I would do that while doing everything else, but I can't figure out how to use the program

You've got a couple options.

CAD programs can work with STL files, but it's not their strength. You might be better off using a mesh-based 3D modeling program, like Blender or Meshmixer, to work directly on the STL mesh. What you're trying to accomplish is called "digital kit-bashing" in the tabletop miniatures hobby. It's a very common thing to do when you buy STLs for wargaming. YouTube has lots on this process.

What printers do you have access to, and what slicing software does it support? I'm only familiar with Orca/Bambu slicers, but I'd guess anything that descends from Prusa would be the same. When you load an STL onto the virtual build plate, you have access to cutting tools that will allow you to cut along a plane, and resizing tools that will let you rescale. You'll probably be able to get 95% close to what you want, but you'll be doing it by eye rather than vertex by vertex in a mesh tool. Your slicer software should have help files on how to cut and scale your models.

Most slicers should allow you to combine files.

I have a Bambu A1 and there software is the only thing I have used

Autodesk has a program called Meshmixer that is free. It will do it, but I have no idea how to use it. But there are videos.

I strated playing around in Bambu Studio yesterday.
I was able to slice off the part I wanted. It wasn't perfect, somehow it was angled, with more material on the diver's side the the passenger's. I need to learn to use the tools better.

It was definitley taller then the front part of the cab, but I think I could figure out how to resize it. Then I will play around with how to mesh them together

Get Meshmixer and learn to use it. It will allow you to do what you are trying to do.
