can autocad use shapefiles
Shapes are objects that you use like blocks. First you use the LOAD command to load the compiled shape file containing the shape definition. Then you use the SHAPE command to insert shapes from the file into your drawing. You can specify the scale and rotation to use for each shape as you add it. AutoCAD SHP fonts are a special type of shape file, and are defined in the same way as shape files. Blocks are more versatile and easier to use and apply than shapes. However, shapes are more efficient for AutoCAD to store and draw.
