You can create customized subassemblies from AutoCAD polyline objects in a drawing.
To create a subassembly from a polyline object, first create the desired polyline object in the drawing. Then convert the
polyline to a subassembly using the command. Add the new subassembly to an assembly by right-clicking it and clicking .
Make sure the polyline object is free of drawing errors. If necessary, use the drawing cleanup tools in AutoCAD Map 3D.
After you have created the subassembly from a polyline, add the desired point, link, and shape codes to the subassembly. If
you do not add any codes to the subassembly, the subassembly does not display when you create the corridor. For more information,
see Understanding Point, Link, and Shape Codes and Adding Codes to a Subassembly.
Use code set styles to control the visual appearance of subassembly components. You can use existing code set styles or create your own.
The origin point of the polyline is used as the attachment point, or origin point, of the subassembly. You can change this
origin point for subassemblies created from polylines using the Modify Origin command. For more information, see Changing the Origin Point on Polyline Subassemblies.
Creating Subassemblies From Polylines
To create a subassembly from a polyline
- Create the desired polyline shape in the drawing.
-
- Click the polyline object in the drawing and press Enter.
- In the Create Assembly dialog box, for Name, enter a name for the subassembly.
Note
To name the subassembly, you can select its default name and enter a new name, or you can use the Name Template. For more
information, see Name Template Dialog Box.
- For Description, enter an optional description for the subassembly.
- In the Code Set Style list, select a Code Set Style or accept the default. For more information, see Code Set Styles.
- Click
to select a layer. For more information about layers, see Object Layer Dialog Box.
Note
If you do not select a layer, the subassembly is placed on the default layer.
- Optionally, select a mid-ordinate distance.
If this subassembly contains curves, they will be tessellated (converted into a finite number of segments). This value determines
the length of the tessellated segments.
- In the Link Creation list, choose the behavior for link creation by selecting Multiple, Single, or None. Multiple is the default.
- Multiple: Creates a new link for each segment created from the object selected. This is useful for assigning link codes to different
components of the subassembly for creating surfaces, or other display features.
- Single: Creates one link from all segments created from the selected object. This is provided to make creating shapes simpler. Using
the Add Shape right-click command, you only need to perform one action.
- None: Produces no links; only points will be created at the vertices.
- Optionally, you may clear Erase Existing Entities if you want to save the original polyline object selected to create the
subassembly. By default, this option is checked and the polyline selected is automatically deleted.
- Click OK. The new subassembly is created and is displayed in the Assemblies
Unassigned Subassemblies collection in the Prospector tree.
To add codes to the subassembly, see Adding Codes to a Subassembly.
To add the subassembly to an assembly, see Creating Assemblies.
