How to Draw a Walkway Using Polyline in Autocad

Procedure for creating and using polylines as asset paths.

Manually create an asset path

An asset chain path can be created quickly from the AutoCAD command line using a combination of straight lines, arcs, or 90 degree turns. The Arc option is only available for those assets that can follow a curved path. These assets include conveyors, cable trays, electrical conduit, and pipes. The 90 degree Turn option appears for guard rail, hand rail, safety fence, and wall assets. Similar to using the Polyline command, a Close option also lets you close the asset chain back to its start point.

1. Begin a new, or open an existing, 2D layout.
2. Click Factory tab > Tools panel > Palettes, then click Asset Browser from the drop-down menu.
3. Open the System Assets folder, and then open the appropriate subfolder to access chainable conveyors, walls, and safety equipment.

Note: Chainable assets appear in the asset browser like this:

4. To place an asset, click and drag the asset from the browser into the graphics display and release the mouse button.
5. The asset has a base point definition and is ready for you to specify that location in the layout.
6. Click to place the beginning of the asset chain at the Pick a start point or select polyline [Polyline]: prompt.
7. At the Next Point: prompt, enter a numeric value (like 45') or interactively draw the second segment of the asset chain. By default, the segment is drawn as a straight line using the default Line command option.
8. If the selected asset can be included in a curved path, the Arc option appears on the command line. Press A on the keyboard to invoke the Arc option to add one or more curved segments to the asset path. Press L to return to drawing straight asset chain segments.
9. If the selected asset can be routed into a right-angle turn, the Turn option appears on the command line. Press T on the keyboard to invoke the Turn option to add one or more 90 degree segments to the asset path. Press L to return to drawing straight asset chain segments.
10. Continue drawing segments as required. Press C on the keyboard to invoke the Close option if you wish to close the asset chain back to its start point and end the command.
11. If not using the Close option, press Enter from the keyboard or right-click and select Enter (or Cancel) from the pop-up context menu when you are finished.

The chainable asset route is now complete.

Using a polyline as an asset path

An existing 2D polyline can be used to define the path for an asset chain. As an example, one polyline could represent walls, a second could define a belt conveyor path, and a third could represent guardrails surrounding the conveyors.

1. Begin a new 2D layout and draw one or more polylines that represent asset chain paths.

2. Alternatively, open a layout with one or more existing polylines.

3. Select the Factory tab > Tools panel > Palettes > Asset Browser from the drop-down menu.

4. Open the System Assets folder, and then open the appropriate subfolder to access chainable conveyors, walls, or safety equipment.

   Note: Chainable assets appear in the asset browser like this:

5. To place an asset, click and drag the asset from the browser onto the graphics display and release the mouse button.

6. At the Pick a start point or select polyline [Polyline]: prompt, press P from the keyboard to invoke the [Polyline] option.

7. You are then prompted to select the polylines to convert into a chainable asset route.

8. Select one or more polylines and then press Enter to end the command.

The polyline you selected is highlighted and converted to a chainable asset route.

Convert your polyline of chained assets into individual assets

To convert your polyline of chained assets into a visual representation of individual assets in you AutoCAD Factory layout:

1. Draw one or more polylines that represent asset chain paths.
2. Select and highlight the polylines you would like to convert into asset chains.
3. Do one of the following:
   • Select the Convert Asset Chains option from the Factory AutoCAD ribbon.
   • Select the polyline, right click, highlight the Factory option, and select Convert Asset Chains from the right-click context menu.

The selected polyline is now populated with individual instances of your chained assets. You can also populate your polyline with assets using the Open in Inventor command.

Once the polyline is populated into individual assets, the nonstandard assets display in red (default color).

To select a custom color for nonstandard asset instances in your asset chain, open the AutoCAD Options > Factory Assets tab in AutoCAD Factory and select a custom component color.
