Solid 3D shapes

Is it possible to infill a 3D shape in Sketchup?
More specifically, I am aiming to show construction detail using section planes and require cross sections to have visible faces rather than appear to be an open box.
Is there a plug in or direct method of acheiving this?
I’m finding that I need to draw specific cross section models for construction details rather than take from the actual project model.
Any help would be greatly appreciated!

Skalp for SketchUp

I can thoroughly recommend Skalp for Sketchup. Works extremely well and allows you to assign different hatches/patterns to different objects.

As mentioned, Skalp ia a plugin designed specifically to do what you want.

If you want a kludge work around without any plugin, it can be done:

  1. Draw a plane where you will be making a section cut, and make it a group so it’s isolated form everything.
  2. Edit that group, and intersect that plane with your model.
  3. Erase everything but the poché fill part you want.
  4. Snap a section plane to this plane. (it will disappear in the process)
  5. Either move the section cut back, or your poché plane into the model the smallest workable amount, like 1/16" or 1mm.
  6. Keep that poche on it’s own layer with a scene for that section view.

This can be condensed:

  • place your section plane
  • right-click on it and select “create group from slice”
  • enter the created group and redraw an edge to fill it (provided your model forms closed loops). close the group
  • move back the section for a bit

Oh, right! I forgot the purpose built command to do the task.

Dibac extension also has an option to display ‘solid sections’
