Not able to Add an item to a Selection

[BoredDrawing]

Hello All,

Catia V5 R19 on XP64bit

I have recently been on the V5 VBA course, and I'm now writing my first program (how sweet!).

The program is to randomize the colours of parts within a product. The products are loaded from our PDM system (VPM via 3D Com to be precise) and it is likely that there are multiple levels or assemblies within the main root node.

The main elements of the program works, (looping up and down the structure, and changing the colour of a series of part within a flat product structure)

The problem that I have is that the program does not correclty select the part visibly in the catia screen. Interestingly the colour does change, but is not visible on the screen but only in the graphic properties toolbar when slecting the part manually in the spec tree.

Therfore the only thing that is not working is the passing the Added element to the selection for the colour to be visible. Any help would be appreciated, I assume that it is a syntax or a missunderstanding on my part.

Thanks.
