Solid View creates a viewport and several layers. The viewport is placed on the Vports layer, which is created if required. Each viewport is given a name. This name is used to create four layers per viewport: <name>-DIM (dimensions), <name>-HAT (hatching), <name>-HID (hidden lines), and <name>-VIS (visible lines).
- Do not put anything else on these layers (except for the layer Dimensions), because Solid Drawing automatically deletes and updates the information stored on them.
- Change the linetype for the -HID layers so that they display with hidden lines, as shown here:
- You can change the color of any of the layers as required.
- Hatching created in sectional views uses the current values set in the Hatch command. Double-click on the hatching to modify it once it is in the drawing.
