I've been given an old User Command to reprogram in VBA so that it functions in MS CE.
The User Command places cells using a transformation matrix to mimic placement on either the top, left, or right planes in a 2D model.
The part I'm having a problem deciphering is this series of statements
SET TMATRX(1) = XAXSCL * A3 SET TMATRX(2) = YAXSCL * A5 SET TMATRX(3) = XAXSCL * A2 SET TMATRX(4) = YAXSCL * A4
I get the how to replicate the replications on the right side of the = sign.
How do the TMATRX(1) -> TMATRX(4) values translate to a MicroStation VBA Transform3d?
Hi Rod,

My experience, not specific to UCM > VBA, but general, when not similar languages or environments are used, is to focus on functionality, not original code. Otherwise there is a threat the new code will follow too much another, not own, philosophy.

It looks like it sets transformation matrix as a multiplication of x (or y) active scale and some variable (A2 ... A5).

I remember literally nothing from UCM ;-) but as I wrote above, important is functionality, not UCM code.
In MicroStation VBA, there are many functions available to set rotation and transformation matrices.
