3Pt Align

3Pt Align

Win64, English

Martin Breidt
Utility to precisely align an object to another, using three source and three target points.

General Usage Instructions

Select an object, then run the macroscript. Next, pick three source points (typically three points on the object, but that is not a requirement), followed by three target points. After picking the sixth point, a dialog will appear with some additional alignment options.

Commands

Ribbon/Toolbar Icon Command Command Description

Z Offset

Shift the aligned object along the z axis (the direction perpendicular to the plane created by A1-A2-A3)

Invert alignment

After the alignment, scale the aligned object uniformly by -100%, effectively flipping the object around the first point (A1)

Scale

Uniformly scale the object by this percentage after alignment around the first point (A1)

Auto Scale

Enable this option to automatically compute the correct scale factor such that the distance between A1-A2 matches that between B1-B2
