Creating a 3D Model for a Block-Based MvPart
Use this procedure to create a 3D model for a block-based MvPart. To support automatic generation of view
blocks by Content Builder, the model block must be created using AutoCAD
®
solids in the standard AutoCAD
world coordinate system (WCS).
NOTE
To ensure correct hidden line display when placing the MvPart in a drawing, be sure to create a single
body using AutoCAD solids for the model for the part.
1
Create the 3D model of the part size.
2
To add points on your model to help locate connectors, enter point, press
ENTER
and, using
object snaps, select the center of a connector on the 3D model.
Add AutoCAD point objects in the location of the center of all connections. This lets you use
Node object snaps to select the connection points when assigning connectors.

Click View tab
➤
Coordinates panel
➤
World
to set the user coordinate system (UCS)
to World before making a block.
For more information about coordinate systems, see “Control the Display of the User Coordinate
System” in the AutoCAD Help.
4
Verify that the geometry is drawn on layer 0 and is assigned BYBLOCK for color and linetype,
and BYLAYER for lineweight. This helps to ensure display control for the part size.
5
Click Insert tab
➤
Block panel
➤
Create Block
.
The Block Definition dialog is displayed.
6
In the Block Definition dialog, enter a name for the model block.
Use a standard naming convention that represents the part family and part size as you save your
model block. For example, a model block for a roof-mounted air handling unit for a commercial
building, with an outlet size of 24 x 24 inches, could be named AHU Commercial Roof 24x24
model.
7
Under Objects, click the Select Objects option, and then select the geometry that will make up
the model block.
The dialog closes temporarily while you select objects for the block. Press
ENTER
when you finish
selecting objects. The dialog reopens.
8
Under Objects, select one of the following options:
■
Retain.
Keeps selected objects in the current drawing in their original state.
■
Convert to Block.
Replaces selected objects with an instance of the block.
■
Delete.
Removes selected objects after the block is defined.
9
Under Base Point, click the Pick Point option and select the model block insertion point.
