Hello,

I need to generate an approximate extent in plan of a number of pointclouds.
The method works outlined below, but is quite laborious and slow.

I was wondering if anyone had a quicker method ?

Can you try instead the 'Tools > Fit > Facet' method?

To build a 'facet', CC will try to extract the concave 'contour' which is a polyline and can be exported directly to DXF (the facet is actually a composition of several entities).

Maybe you'll need to flatten the point cloud first (depending on how the resulting facet orientation). This can be done more quickly with the 'Edit > Multiply / Scale' (set the Z scale to 0).

thanks Daniel, that is certainly much quicker
