To Create an AutoCAD-Based Symbol From Scratch

1. If necessary, open the parametric MvPart in Content Builder.
2. In the part browser, right-click Symbol and Annotation Plane, and click Visible.
   Note: Although this step makes the plane visible in the drawing area, its position on the Z axis in the World Coordinate System (WCS) is high above the WCS origin, so you might need to zoom out to view the plane. You can also change the position of the plane if desired.
3. Right-click Symbol and Annotation Plane, and click Set View.

   This changes the view direction to Top (plan) view, which is the default view for the plane as well as the most common view for drawing schematic symbols. However, you can select any view that is helpful for drawing the geometry.

4. Draw the geometry of the schematic symbol using standard AutoCAD objects, such as lines, arcs, and circles.
   Tip: Use the Isolate Plane Contents, Hide Plane Contents, and End Object Isolation commands on the context menu of a plane to show or hide the geometry on the plane.
5. In the part browser, expand Symbol and Annotation Plane, right-click Design Blocks, and click Add Schematic Block.
6. Select the plane along which to orient the 2D symbol, select the geometry of the symbol, and press Enter.

   Typically you orient the symbol along the Symbol and Annotation plane. To do so, press Enter to accept the current plane. However, you can also select a different plane. For example, you might want the symbol to show in side views instead of Top view for use in section and elevation drawings.

   You can select any geometry except parametric geometry created using Content Builder, which is filtered from the selection set.

7. Specify whether to erase the source geometry of the symbol:
   • Enter n (no) and press Enter to keep the source geometry in the part.
   • Enter y (yes) or press Enter to erase the source geometry.

   The schematic symbol is attached to the Symbol and Annotation Plane regardless of the plane where it is oriented. Therefore, the software adds a Design Block to the Symbol and Annotation Plane under Design Blocks in the part browser.

   

   Adding design block

   Design Block represents the schematic block that you have added. Typically, you create only one symbol and, therefore, only one Design Block for a part.

8. If desired, add annotation to the schematic symbol.
9. If desired, specify the use of the schematic symbol instead of a model-generated view in 1-line and 2-line display representations in Top (plan) view:
   • In the part browser, click .
   • In the Options dialog box, click Display Symbol In Plan View, and click OK.
10. Click (Save Part Family).
11. Click to close the part browser.
