Undet for AutoCAD 2025 – Fast Shade Mode and Color Display in Wireframe

1. Why are the point cloud colors not displaying correctly in Wireframe mode?

When you first install and open Undet for AutoCAD 2025, you might notice that point cloud colors don’t display correctly in Wireframe mode. This is likely caused by AutoCAD’s Fast Shade Mode, which could be enabled by default.

2. What is Fast Shade Mode?

Fast Shade Mode is a rendering optimization setting in AutoCAD that enhances display performance but can sometimes prevent the correct visualization of colors in point clouds, especially in Wireframe mode.

3. How can I ensure point cloud colors display correctly in Wireframe mode?

To resolve this and display colors properly, you’ll need to turn off Fast Shade Mode. Here’s how:

1. Open AutoCAD 2025 with Undet installed.
2. In the AutoCAD command line, type the following command:
   FASTSHADEMODE

3. Press Enter.
4. Type 0 and press Enter to turn off Fast Shade Mode.
   

After turning off Fast Shade Mode, the point cloud colors should appear as expected in Wireframe mode.

4. Will disabling Fast Shade Mode affect AutoCAD’s performance?

Disabling Fast Shade Mode may slightly reduce rendering speed in complex models. However, it ensures that point cloud colors render correctly in Wireframe mode, which is essential when working with Undet for AutoCAD.

5. Do I need to disable Fast Shade Mode every time I open AutoCAD?

No, once Fast Shade Mode is turned off, the setting will stay disabled even after restarting AutoCAD. You only need to perform the steps again if you manually re-enable Fast Shade Mode.
