If you hold your CTRL and Shift Key, you can draw a straight line. The trick, hold your CTRL key and draw a highlight line.

This happens a lot in congested areas of your drawings. So, if Vector drawings are better why can’t I highlight just one small part of my drawing? The advantage of a Vector drawing is the lines and text are recognized as such rather than dots on the paper. Vector drawings are crisp drawings created directly from a CAD software. Raster drawings are typically scanned documents consisting of pixels that can be difficult to work with. There are two types of PDF drawing files, Vector and Raster. When I try to highlight something on my drawing it highlights the entire sheet!
