First of all, draw a help line from the desired viewer's position to the desired target's position.
Select it, go to the PROPERTIES PANEL and set the ELEVATION value to 1.7m (viewer’s height).

Type DVIEW, select all the building’s objects you want to be shown except the help line and press ENTER.
Type POINTS, click on the line’s end point to set the target's position and then click on the opposite start point to set the viewer’s position.

Type DISTANCE, enter a value in meters to adjust how far is the viewer from the building and hit ENTER.
Type ZOOM, enter a value in millimeters to adjust the lens focal lenght and hit ENTER.
Press ENTER once again to exit the DVIEW command.

Finally, in order to save the generated view, type VIEW and hit ENTER.
Type SAVE, press ENTER and input the dessired cammera name i.e. CAMERAFRONT.
You can restore the saved view anytime by typing again the V command followed by the RESTORE option.

Hi Frédérique,

I attached AutoLISP file which can help you to work with DVIEW command (create camera view).

Use APPLOAD to load it, then use SET_CAM command to create camera view.

The routine will:

- set view to plan

- ask for camera point location in plane

- ask for target point (view direction)

- ask for camera level above current UCS (or WCS) plane

- ask for camera focal length (lower values will give you wider view angle)

- create perspective view (camera view)
