Hi, I'm using an object Y position field as an attribute for a block. This is what I use:

%<\AcObjProp.16.2 Object(%<\_ObjId 2118086344>%).InsertionPoint \f "%lu2%pt2%pr4%ps[+, M]%ct8[0.001]">%

What I would like to do is an arithmetic operation of addition, something similar to how 'CAL works. In this particular case I would like to add the value of 100,000 before the conversion factor, or 100 after the conversion factor.

Thanks.

Yes, you can do this. See the tip:

http://www.cadforum.cz/cadforum_en/qaID.asp?tip=6381 - http://www.cadforum.cz/cadforum_en/qaID.asp?tip=6381

The resulting expression will look similar to:

%<\AcExpr (100+%<\_FldPtr 305306904>%) \f "%ps[+, M]">%

and

%<\AcObjProp Object(%<\_ObjId 2129671616>%).InsertionPoint \f "%lu2%pt2">%
