I’m trying to rebuild the surface so its isocurves form a regular 1m grid as seen from top view. I got pretty close but not exact. Any ideas on how to achieve this (hopefully without GH)? File attached.
Well, yeah, it does involve the use of a script to create the surface - and one ‘manual’ adjustment.
Basically it’s this:
Untrim your base surface, keep the trim curve
Make a grid of points from your line grid (I used Intersect)
Project the points onto the untrimmed surface (the script can take a point cloud, so you can point cloud the result if you want, but not necessary)
Run the script with the points or point cloud to create the surface
Re-trim the surface with the trim curve.
The important details:
In the script, chose InterpSrf, not CtrlPtSrf as a command line option
Once the surface is created, you need to InsertKnot a new knotline at the four outer edges of the surface - the surface creation method from a grid of points always makes surfaces this way for some reason. You can snap to the grid points to guide the creation of those knots.
The script basically takes a set of points that are organized in a precise rectangular grid but possibly unordered and tries to re-order them correctly into rows/columns order make a surface from them.
