You can convert CAD objects on individual layers into Microsoft Office Visio shapes, and then modify or delete the Visio shapes. For example, you might want to move an interior wall in a CAD floor plan that you have converted.
When you convert a drawing in AutoCAD DWG or DXF format, you convert the last saved spatial view of the CAD drawing. A CAD drawing may have been saved in model space or paper space:
Model space is the primary drawing workspace in which CAD drafters create drawings.
Paper space is a workspace that is analogous to a sheet of paper, in which CAD drafters can arrange different views of the drawing.
When you convert a drawing saved in model space, all objects and text on the layers you select are converted into Visio shapes. When you convert a drawing saved in paper space, only the objects that are not cut off (clipped) by the edge of the viewport are converted into Visio shapes. Objects and text that are cut off are converted into lines.
A circle that is completely enclosed by a viewport is converted into a Visio circle shape. A circle that is clipped by the viewport is converted into a series of lines.
Right-click the CAD drawing, point to CAD Drawing Object, and then click Convert.
In the Convert CAD Object dialog box, select the check boxes for the layers that contain the CAD objects you want to convert.
To delete or hide layers in the CAD drawing after converting them, or to specify how to convert dimensions and hatch patterns, click Advanced.
Note: To keep your drawing file size small and speed the conversion process, convert only the layers or levels you need.
