You can import, in a drawing, files and drawings produced in other formats.
To import an external file
Perform the following operations:
Choose the File » Import command or click the tool in the toolbar. The dialog box for selecting the file appears.
Select the file and click on Ok.
This operation incorporates data from external files produced by other programs into a drawing. The data format is changed and any reference to the source program is lost. If you want to be able to modify the data at a later time, you must incorporate the data as an OLE object.
