The Step 3D CAD (STP) file is a 3D assembly file that is supported by a number of mechanical-design software applications and is used as a 3D product model data exchange format. AutoCAD Drawing Database (DWG) files are databases of 2D or 3D AutoCAD drawings. These files are vector files that store design data and metadata that describe the contents of the file. When sharing these types of files with colleagues or clients, it may be necessary to convert a STP to a DWG to allow them to properly view them. Autodesk Labs' Inventor Fusion Technology Preview makes this a simple task.
Open a web browser and visit the Autodesk Labs' Inventor Fusion Technology Preview home page (see Resources).
Press the "Download Now" button, fill out the required form information and click the submit button to begin the download. Double click on the downloaded file and follow the onscreen instructions to install the program.
Launch the program from the "Start" menu or desktop icon.
Click the "Open" button, select "STEP Files" as the file type in the drop-down menu and browse to the location of the STP file. Select the desired file and click the "Open" button to open the file.
Click the "Save As" file and select "DWG Files" as the file type in the drop-down menu. Click the "Save" button to convert the STP to a DWG.
