How to model properly with clipping planes and point clouds?

Its easy really :slight_smile:
I model from pointclouds all day, every day.

  1. Create a clipping plane

  2. Copy and paste the clipping plane into its original position.

  3. Move the second clipping plane to your desired slice “Thickness” and flip it.
    (This should create a thin slice through your cloud etc)

  4. Group the clipping planes so they move as one.

  5. Create a “Mobile Construction Plane”

  6. Attach it to one of the Clipping planes

Now…when you move your clipping planes, the Mobile Construction Plane will follow.
Whatever you draw will be on that mobile construction plane. You can also obviously rotate the construction plane in 3D etc.

You can also Snap the clipping planes to points (in a pointcloud), or to reference objects (lines etc)
using a second viewport that isn’t clipped by the clipping planes.

If you want to be really exact, create a rectangle exactly between the two clipping planes and attach the Mobile Construction plane to that, this is your exact reference plane.
