help with 2D CAD blk for custom symbol

I created and imported a symbol from SU using file> import 3D symbol using the 'advanced' option. I also created a custom 2D CAD block that I want to use as the 2D symbol for that item, which I specified in the '2D block' tab during import.
The problem is, the CAD block I created included a filled polyline shape, but the fill doesn't show up in the 2D block for the symbol. (see attached) When I blocked the CAD symbol, I checked 'fill by object'.
To compound my confusion, the 2D block tab in the import symbol dbx doesn't have item 3 as shown in the X2 ref. manual (see pg 965)
What am I missing here?

Thx, Dorothy

I'm sure I'll get corrected on this Dorothy, but I don't believe you can apply a fill to the Electrical 2D, or at least I've tried with no success.

morning dorothy,

i don't have X2 yet but you couldn't apply fill to electrical cad blocks in previous versions.

what i did was to set the concentric snap to the smallest i could (1mm here (metric) try 1/16) then select the polyline i wanted filled & multiple copy the line into the centre of the polyline shape. printed to scale the symbols look solid--and they are saving you ink--how ecologicaly friendly is that.

regards, brian
