topic Re: Invalid 2D symbol in Libraries & objects https://community.graphisoft.com/t5/Libraries-objects/Invalid-2D-symbol/m-p/77898#M32359 Generally, you get this because of poor programming on the part of the object creator. The fix (short of learning GDL and fixing the object itself) is to look for a parameter that you've used that currently has a zero value, and replace it trying a value &gt;0. This message is usually due to a 0. Based on the message you have, the zero value is probably in the trim section of the object parameters.<BR /> <BR /> Usually (and I stress USUALLY) you can use a very small non-zero value and the object will once again work.
