The Display Features tab controls what object types are to be displayed and under what conditions they should be displayed. Any objects that are not displayed will not be used by LISCAD functionality, nor is it possible to snap to objects unless they are displayed.
| Item | Used to |
| Objects | |
| Points |
Turns the display of Points on and off. Note that points can be displayed as dots or crosses depending on the selection made in the buttons on the Points page of this dialog. The 3D Points Only checkbox is used to display only those points that have defined elevations. The Display Disabled Points checkbox is used to include disabled points in the display. The Identifier checkbox is used to display point identifiers. The Code checkbox is used to display point codes. The Elevation checkbox is used to display point elevations. |
| Lines | Turns the display of lines on and off. Full means that lines
are displayed as solid lines. There is no provision to show lines with particular line styles in the 3D view. The 3D Lines Only checkbox is used to display only those lines whose points are 3D points. The Display Disabled Lines checkbox is used to include disabled lines in the display. Lines displayed include straight lines, arcs, circles, splines and spirals. Note that arcs, circles and spirals are defined in the Plan View, thus in 2D, so that they may not necessarily appear as arcs, circles or spirals in 3D - for example, an arc in the 3D View may become something like a spiral staircase. |
| Show Axis Triad | Turns the display of the axis triad on and off. |
| Projection | Controls the projection of the scene. This lets you control how your
3-dimensional scene is to be converted to 2 dimensions for viewing.
There are two settings perspective or orthographic. Perspective means that the camera is to see things the way your eye normally sees things - that which is near to your eye appears large, and that which is far away appears small. Orthographic means the represented size of an object doesn't depend on how close it is - this can be handy in architecture and engineering. |
Objects which have a group attribute that is not selected for display in the Display/Groups command, cannot be displayed, even if they are of a feature type selected for display in this command.
