You can create a schematic symbol for a parametric MvPart at any time. However, only parts that you add to drawings after you have created the symbol can use the symbol. You cannot update previously inserted parts to use the symbol.
There are 2 types of schematic symbols that you can add to parametric MvParts:
- Parametric. This type of symbol scales proportionally with the part. You create parametric symbols using parametric features: parametric geometry, dimensions, and constraints.
- Block-based. This type of symbol scales uniformly instead of proportionally. You create block-based symbols using standard AutoCAD® objects, such as lines, arc, and circles. You can create the symbol from scratch, or you can insert an existing AutoCAD MEP 2022 toolset symbol or 2D AutoCAD block from a DWG file. This allows you to take advantage of existing symbol libraries or block libraries.
