Select points for the creation of geometric shapes. Automatic point selection is constrained to the input shape (planes, cylinders, and spheres).


Fit shapes & select points with constraints

The point selection is used for fitting geometric shapes that approximate the selection. The Brush Selection method is most useful as it will only select points that form a continuous surface rather then picking "through" the point cloud.

Grow selection to fit shape

Feature based selection starts with small selection of points and "grows" the selection based on the input constraint; adjacent points, planar points, or cylindrical points.

Fitting shapes

Selected points are fitted with the appropriate geometric shape; plane, cylinder, or sphere. Use F9 for plane, F10 for cylinder, F11 for sphere or F12 for a corner.

Fit tolerance

It indicates the surface roughness and a higher than default value is especially useful to fit pipes with insulation. 

ASTM pipe

If this option is turned on, the fit radius matches the closest ASTM outer diameter. This option is not suitable for pipes with insulation.

Current fit radius

This UI is visible when a fitted pipe is selected in the object lister or immediately after a fit pipe is created. If you modify the radius, the pipe is fit again with the new radius.


Tip: Use the backspace key to clear the selection of objects and points.
