> sie pinai yra konstruktyviniai ir tiek.. Duodu "allow via ", bet jis kazko vengia

  Visada maniau, kad konstruktyviniai jam yra tie, kuriems duota "non-electric".
Realiai nenaudojau. Dėl visa ko cituoju 9.2 helpą:

To add mounting holes to your board

1   Choose the component toolbar button.
2   From the pop-up menu, choose New. The Add Component dialog box displays.
3   Choose the Footprint button. The Select Footprint dialog box displays.
4   In the Libraries group box, select LAYOUT. Use the Add button, if necessary, to add this library to the list of available 
libraries. (LAYOUT.LLB resides in the LIBRARY directory.)
5   In the Footprints group box, select a mounting hole (OrCAD provides three: MTHOLE1, MTHOLE2, and MTHOLE3).
6   Choose OK to close the Select Footprint dialog box.
7   Select the Non-Electric option, then choose OK to close the Add Component dialog box. The mounting hole attaches to your cursor.
8   Place the mounting hole by clicking the left mouse button.
