Underlays

nanoCAD supports DWF, DWFX, PDF files insertion as underlays.

You caan use common editing commands: Copy, Move, Rotate, Mirror, Scales and others for underlays.

It is possible to change the position, scale and rotation angle of the underlay using the grips: the upper grip is responsible for scaling, the lower right grip is responsible for rotation (relative to the lower left), the left grips (lower and upper) are responsible for movement.

     

Properties dialog box displays some underlay settings: Contrast, Fade, Adjust colors for background, monochrome:

Underlay in the drawing has one grid in the bottom left corner. Use it to move the underlay.

Underlay has a frame that shows max underlay size. Use PDFFRAME system variable to show (1) or hide (0) a frame.

It is possible to set the display border to show only the cropped part of the background. Trimming is performed with the UNDERLAYCLIP command.
