Threads
The
Threads
preferences panel contains preferences for threads. Threads are generally only shown in simplified form in perspective illustration. Parallel ellipse arcs are used to simulate actual threads.
The Distance between these arcs represents a kind of thread pitch but is larger. Using a pitch which is correct from a technical standpoint would lead to printing problems in a perspective presentation since the individual threads would run together. Larger distances are therefore used.
Arbortext IsoDraw allows you to specify the distance as a function of the diameter of the threaded bore or the thread edge. You can enter values for three Thread diameter ranges, as shown on the Threads preferences panel.
| You should note two points when selecting values: 1. If you reduce the drawing for printout or exporting, the distances should be selected larger. 2. If you want to print the drawing on a high-resolution output device instead of on a laser printer, the distances can be smaller. |
