Trimming a Body

[andrewhoodless]

Hello All,

I have a bit of an issue here. I'd like to trim this intersection of bodies and remove the highlighted area back to the inner contour. Unfortunately it is as one body after I joined them some time back.

Any suggestions how I could do this ?

Can you File>Export and then Attach your *.f3d file here?

Will Split Face and Delete Face return the results you are after?

[andrewhoodless]

OK, so here is the .f3d file. You should be able to see the protruding piece from the 2D picture if needed.

Surely it must be able to be trimmed away. I tried a couple of the split commands but couldn't get it to work as I wanted.

P.S I'm wanting to print this on a 3D printer. I hope the wall thickness is enough.

Here's one way to do it:

p.s. 3mm thickness will print with no problem, but the model has a lot of unsupported bridging which your slicer may not be able to handle.  You may have to create custom supports.

Cool !! I did think of doing it something like that but thought there must be a function which could do it almost at a click of a button. Like a trim excess feature. Perhaps that the model walls are joined then this is the way to do it for now.

Will see what the other guys come up with. 🙂

Thanks.

Editing the post removed the screencast.  Here it is again.

I would still be interested in the "split face" solution as I think the final issue I have "around the corner" would be easiest if the planes (following blue wall) could trim that piece coming into the interior.

I guess I am going to need to unlink them in the history tree somehow.

See attached.

In Rev2 example I noticed that there is another face that is extraneous and can be deleted.

This could be removed with the original Delete Face in Rev1, but I did it as a separate Delete Face in Rev2 so that you could more easily discover what I did.

[TheCADWhisperer]

In Rev3 I remove your previous Split Body and replace with Split Face.

Tidy everything together into one Delete Face to clean up the geometry.

Turn on your sound.

Awesome CADWhisperer !!! That's great !! Definitely something which I can use more often to tidy things up.

The video is certainly a great help !

I feel I have a lot of sketches as I'm going along, and it's a messy model, but I guess that's how it goes when you're starting.

I always consider my first attempt (or two or three) to be trials, and then use what I learned from the attempts to start over from scratch and create a clean and robust model.

I look back at stuff I did a year ago (month, week, hour?) and shudder at the rubbish I did back then.

Hi CADWhisperer,

I have trimmed and modified the back side to a straight wall. I have 2 issues now,

1). I see there are some strange lines which I can't seem to delete. See picture circled.

2). I have an extra fixing rib which I no longer need on this corner version. Can't seem to delete it either ? (see picture)

Hey there @andrewhoodless

You could go back in your timeline to where you joined them.

Alternatively you could easily section the main body with the Split body option in the patch menu, then simply delete the new body (Highlighted one)

Hope this helps!

Pretty sure that is not what I would do.

Looking forward to your demonstration of this proposed technique when the OP attaches the *.f3d file.
