How do you move a CAD file to the foreground or background?
When importing a CAD file (such as an AutoCAD drawing) for use within a drafting view, in order for the file to be visible in the drawing view it should be imported or linked to the Current View Only. If you do this, you will be able to move it to the foreground or background by selecting it and then choosing the desired option on the Options bar. When importing a CAD file to use as the basis of a site plan or topo, however, be sure the Current View Only check box is NOT selected. Otherwise you won’t be able to select the drawing for use in creating a topo surface.
