PolyOptimize: Minimize the Number of Vertices in a Polyline

F/X Admin ribbon, PolyOptimize flyout

Type FX_PolyOptimize in the Command line

F/X Admin menu, PolyOptimize option

Select the polyline you want to simplify.

In this example, we'll use PolyOptimize to reduce the number of vertices in the complex polyline pictured to the right.

The Poly Optimize dialog box will open, allowing you to fine-tune exactly how you want to simplify the selected linework.

1. The number of vertices in the selected linework before optimization.

2. The number of vertices in the selected linework after optimization at the current settings. This number will likely change as you select different optimization methods.

3. Select an optimization method. Each option from Gentle to Extreme will employ a stronger level of optimization, often resulting in a smaller number of vertices in the selected linework as you go down the list. The Custom option allows for even more fine-tuning.

4. If you select the Custom option, you can set a Minimum Angle and Minimum Length in your current drawing units for each vertex during the optimization.

After we've selected the polyline, the number of vertices has decreased considerably.

You can try running PolyOptimize again to further simplify the polyline, possibly choosing another optimization method.

Here's what the polyline looks like after another round of PolyOptimize.
