Hi everyone,
I am trying to read custom lines from the dgn file and draw it into MapControl.
But I don't know how get/set and change line style scale factor of Line ?
Please see this link for more detail about scale factor http://communities.bentley.com/produ...ion-v8-cs.aspx
And I used below codes to draw my lines:
Thanks and best regards,
Tai

Code:

oActiveView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);Tai
