Short description
π MTM2 is an AutoCAD AutoLISP midpoint move and midpoint copy utility that relocates selected drawing objects from a source midpoint to a destination midpoint using UCS-aware coordinate transformation.
Command:
π§° Main commands:
– MMid2 – move selected AutoCAD objects from a calculated source midpoint to a calculated destination midpoint.
– CMid2 – copy selected AutoCAD objects and place the copied result from the same source midpoint to the destination midpoint.
Description:
π MTM2 provides a fast midpoint-to-midpoint workflow for AutoCAD drafting and Civil 3D production drawings.
π The tool lets the user select one or more objects, define a source reference with two picked points, define a destination reference with two picked points, and then move or copy the selected objects by the calculated midpoint vector.
π The source midpoint is calculated from the Y values of P1 and P2 while preserving the X and Z values from P1. The destination midpoint is calculated as a full 3D midpoint from P3 and P4.
π The resulting translation vector is transformed from UCS to WCS before applying the move or copy operation, making the workflow suitable for drawings using custom UCS orientations.
𧱠Objects on locked layers are skipped to avoid modification errors during batch processing.
Helper function: (if any)β
𧩠Main internal function:
– MOVE_COPY_COMMON2 – shared move or copy routine used by MMid2 and CMid2.
π§ Important AutoLISP and Visual LISP operations:
– ssget for object selection.
– getpoint for P1, P2, P3, and P4 reference picking.
– trans for UCS-to-WCS point and vector conversion.
– vla-move for moving objects.
– vla-copy for copy mode.
– vla-get-Layers and vla-get-Lock for locked-layer checking.
Functionalities:
β
Select multiple AutoCAD drawing objects for midpoint-based relocation.
π Define a source midpoint using two picked reference points.
π― Define a destination midpoint using two picked reference points.
π Move selected entities with MMid2.
π Copy selected entities with CMid2.
π Respect the active UCS by transforming base point and vector data to WCS.
π Skip objects located on locked layers.
π§° Use a single shared engine for move and copy behavior.
Result:
β
The result is a precise midpoint-alignment workflow for quickly moving or copying selected AutoCAD objects from one reference location to another.
ποΈ It is useful for CAD alignment, infrastructure drafting, block/object repositioning, profile or section drafting assistance, and repeated object placement where midpoint reference control is faster than standard manual MOVE or COPY workflows.
