Section depth in SketchUp heaven

I’ve seen other posts about this, but they all seem to be closed to further comments and I’d really love to breathe new life into this, if possible. Here’s my feature request: The ability to define a limiting depth for a section cut. Please don’t respond with the standard workarounds as I’m aware of all of them. I think it would be great to have this functionality built right into SketchUp.

In my vision of SketchUp heaven, this is how it would work: when you right click on a section plane, there would be a new menu item - say “Set section depth”. Choosing this would bring up a little dialog box where there would be checkboxes for “Zero” and “Infinite”. “Infinite” would be pre-checked (because this is, and should remain, the default section depth). If you check “Zero”, then all geometry would disappear except for the 2D slice intersected by the section plane itself. (This would be a little bit like the “Create group from slice” option.) If both “Infinite” and “Zero” are unchecked, a second, parallel section plane would appear opposite the initial section plane, allowing the user to place it to define the end of the section swath. Other than the ability to be selected and moved independently, the two opposing section planes would otherwise behave as a pair. They would have the same name and the same active/inactive status. The dialog box could also contain an input field where the user could enter a numeric distance between the start and end planes, if preferred. Then, the resulting section would only display the geometry that lies between the two planes.

Maybe there should also be a “Sections” tray to help the user manage the various sections. And the active/inactive status of all sections would also be toggleable from within a Layout viewport.

In my SketchUp heaven, that’s how it would work.


I second your vision, what can we do to incentivize this feature for Trimble and Sketchup development team.

Maybe I’m missing something, but how is this different than just moving the section plane? Is what you’re after the buttons?

Good feature request. No need to add a tray, I think. Or you could have more than one active section at a time, that would allow this and other configurations.

Yeah totally! I never understood why this isnt available.

In other software you can define a box to use as a view clipping area…and this pretty helpful to do cutaway drawings etc.
Could this be added as an extension I wonder???

Using a sketchup component as the “clipping box” would be a smart method.
Section planes can get pretty complicated to manage (number, organise, activate/deactivate)…

I guess I don’t use so many sections as other people. I figure there are ways of working with them through the outliner and entity window. Or perhaps an organizer would make a good plugin.

This can be faked with 2 sections planes. See this SU file.

Still it’s a good feature request.
