When to use an advanced crop
Use PCBOXCROP when the boundary must remain editable in 3D, PCSPHERECROP for a compact object or joint, and PCBUFCROP for a constant-width corridor around a line or polyline. Rectangle, circle, polygon and slice crops remain in the basic crops guide.
Editable box crop
The box starts from the full cloud bounds and updates when its face grips move. Run PCBOXCROP, select the cloud, then drag the grips around the working area. Running the command again offers Modify, Restore, Hide and Delete.
Spherical crop
Run PCSPHERECROP, snap the centre to the scan and set the radius from the live preview. This is well suited to valves, joints, fixtures and other features where a rectangular volume retains too much surrounding data.
Buffer crop along a route
- Run
PCBUFCROP. - Draw a centreline or select an existing line or polyline.
- Move away from the route to preview the half-width.
- Click or type the value to crop the full-height corridor.
Save useful crop states
Use PCCSSAVE to name the finished crop and PCCROPSTATEMANAGER to restore or remove saved states. Use descriptive names tied to levels, zones or disciplines.
