You can change the default color by clicking the button labeled '''Color''' to open up the standard color palette. You can edit an existing color through its Property Dialog. Right click on the name of a color group on the Navigation Tree and select '''Properties...''' This opens up the Property Dialog of the selected color. You can change the name, color or texture of the group just as explained later.
By default, the color groups do not have a texture. You can replace a solid color with a texture that is generated from a bitmap. First, you have to check the box labeled '''Texture'''. This enables the texture section of the dialog. Click the '''Texture''' button to invoke Windows' Open Dialog. The file type is set to "Bitmap Files (*.bmp)". Use the Browse button to find the desired bitmap file and open it. Next, you have to define the texture mapping scale. On the objects, the texture will show up as tiles of the imported bitmap. In the Texture Geometry section of the dialog, two boxes show the '''Width''' and '''Height''' of the bitmap in pixels. You need to map these onto the desired tile width and height in project units. These settings determine how many texture tiles appear on each object given its dimensions. If large values are set for the tile width and height, partial bitmap will show up on the objects. You also have the option to apply the texture to the '''Side Only''' by checking the related box.
