The command is Undoable, NOT Queryable, and NOT Editable
When copying from left to right (or from right to left), the center row of vertices usually is the border where the copying starts. Since this might result in unwanted corners, the command can blend the sides in a certain region. See the mirrorGeo manual for more information.
The command needs a symmetrical reference object that it can use to find out which right point belongs to a left point. Without this, it wouldn’t be clear how the points correspond and no mirroring would be possible. Symmetrical objects are either geometry or a bcs node.
One of the flags
// These examples assume you have selected an asymmetrical object and have // another object, called "symm", that is a symmetrical version of it. // Mirror the point positions from the left to the right side of the selected // object using the object "symm" as the symmetrical reference object. DPK_mirrorGeo -so "symm" -lr; // To avoid ugly corners, we can use the blend region. DPK_mirrorGeo -so "symm" -b 0.3 -lr; // This will make the left and right side equal by making them akin to each // other. DPK_mirrorGeo -so "symm" -b 100 -lr;
