The Quarter Arc tool creates circular 90 degree arcs or 90 degree elliptical arc polyline objects. The Push/Pull mode is available in 3D views for instantly extruding the arc after creation.
Quarter arcs are listed as polylines in the Object Info palette.
To create quarter arcs:
Click the Quarter Arc tool from the Basic palette.
The Arc tool and Quarter Arc tool share the same position on the Basic palette. Click and hold the mouse on the visible tool to open the Pop-out Tools list and select the desired tool.
Click at the start point for the arc.
Move the cursor until the desired arc shape and size is previewed, and then click to set the arc. To constrain the angle of the quarter arc to 45 degrees, press the Shift key when drawing the arc.
