When you select a property, its colormap should appear in the Secondary Style toolbar. You can also access it by opening that property’s Style Editor.
Using the pencil, draw on the colormap to edit the property’s transparency. 
You can also use the following tips:
- Hold down the ALT key to keep a constant transparency.
- To create a binary (0% or 100%) transparency, use the CTRL key.
- To reset the transparency settings to none, click the middle mouse button.
Previous tips can be found under the Software tip category in the News section and in the Archives section of our website.
