To Create Subassemblies From Polylines

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 Create Subassembly From Polyline command. Add the new subassembly to an assembly by right-clicking it and clicking Add To Assembly.

Make sure the polyline object is free of drawing errors. If necessary, use the drawing cleanup tools in AutoCAD Map 3D.

Use code set styles to control the visual appearance of subassembly components. You can use existing code set styles or create your own.

To create a subassembly from a polyline

1. Create the desired polyline shape in the drawing.
2. Click Home tabCreate Design panelCreate Subassembly From Polyline Find.
3. Click the polyline object in the drawing and press Enter.
4. 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.
5. For Description, enter an optional description for the subassembly.
6. In the Code Set Style list, select a Code Set Style or accept the default.
7. Click to select a layer.
   Note: If you do not select a layer, the subassembly is placed on the default layer.
8. 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.

9. 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.
10. 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.
11. Click OK. The new subassembly is created and is displayed in the AssembliesUnassigned Subassemblies collection in the Prospector tree.
12. 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.

To change the origin point on a polyline subassembly

The origin point of the polyline is used at the attachment point, or origin point, of the subassembly. The origin point is the point where the subassembly attaches to an assembly baseline, or to another subassembly. You can change this origin point for subassemblies created from polylines using the Modify Origin command.

1. In the drawing, or in Toolspace, select the polyline subassembly.
2. Click Subassembly tabModify Subassembly panelModify Origin Find.
3. In the drawing, click a location on the subassembly where you want to specify the new origin (attachment point).
