Q - question

Dynamic label of 3D coordinates.

A - answer Using automatic text fields referencing the properties of a block reference, you can create a 3D block with a dynamic label of the X/Y/Z coordinate of its insertion point. So you can easily dimension "ordinate" points in 3D - e.g. corner points on your 3D model.

An example of such block can be downloaded from the Block Library - Block 22452: XYZlabel.dwg. When pasted with the appropriate 3D osnap modes, the block will display the values of the individual components of the insertion point coordinate - X, Y and Z (in the planes of that component coordinate).

An example:

To update the listed coordinates after a subsequent move of the block reference, you may need to perform the UPDATEFIELD command or a quick save of your DWG drawing (QSAVE, Ctrl+S), not just a REGEN (if you don't use a 2D Wireframe viewport).
