Symbol Templates

User-defined symbols (consisting only of 2D drafting elements) may be created as Symbol Templates (SYTMs). These can then be picked from a Library sheet element, with position, size and orientation attributes being altered to suit. The relevant part of the Draft database hierarchy is shown overleaf.

Symbol Library (SYLB) and Label Library (LALB) elements can be regarded as ‘Sheets’ that can be displayed in an area view. Symbol Templates can then be created on the Library sheet using the 2D drafting elements.

Setting the TMRF (Template Reference) attribute of a SYMB (Symbol Instance) element or SLAB (Special Label) will cause the referenced SYTM to appear on the relevant Sheet. The Symbol can then be positioned, sized and orientated to suit - see the description of scaling and mirroring SLAB elements in Scaling and Mirroring Special Labels for further information of how to do this.
