I have some problems when i use the underlayer function in Draftsight 2017. When i am drawing on top of the underlayer its not possible to select multiple lines by dragging the cursor across the area.
The underlayer is placed in layer 0 and its locked, and i am drawing in a different layer. Its seems like that the underlayer always will be on top regardless the selection state.
If i am unlocking the underlayer, then it's possible to select by dragging but the reaction is that the underlayer is mowing in the same drag.
In the attach file the gray lines is the underlayer, and the red lines is what i had to draw on top.
I hope you understand my written english (I am Danish)
