Trim tool in 3D...

[shorter]

It would be great if the trim tool worked on 3D objects to generate a 'solid subtraction'.

@shorter does the split tool not accomplish what you're after, or do you have an idea to change it in some way?

The split tool only works in one plane.  Which is fine in this instance, and that's what we used, but when another 3D object meets a more complex geometry...

After the initial Split edit the Nurbs Cut-Plane in 3d to achieve a 3d split.

I just to toss into the conversation that Model < Section Solids can be used for more complex 3D cutting.

 

Note that using the Split tool actual creates a "Solid Section" which is the same object type as the menu command, but the menu command allows you to start with a more complex cutting surface as needed.

I was mixing up Trim & Split tools.

Here is a very simple example of what I am looking for with the Trim Tool.

 

 

I would like to simply use the Trim Tool to remove the lower section of the cylinder that hangs below the rectangular geometry.

 

I would like to do this with one click.  I would like to not have to select anything.  I would like to not have to create another object.  I would like to not have to go into another view to use the split tool.

 

If these were 2D objects, I would simply select the trim tool and it would trim the 2d object to the nearest object.

 

Not so in 3D.

 

Yes, I know there are other tools that would do this but what I wish for is the Trim Tool to do this with greater ease and efficiency.

 

Trim Tool will throw up an error...
