    <font color=”#000000″>Hi. I am using AutoCAD Mechanical 2016 and going thru lesson on intersect. I typed INTERSECT on the command line, enter, selected 2 objects, moved cursor outside of objects and pressed enter. Received message Selected Objects: 1 found, 2 total Selected Objects: At least 2 solids, surfaces, or coplaner regions must be selected. Not sure what I should have done differently.

    Also ran into an issue with UNION I made region of 2 circles and 1 rectangle. When I went to make UNION it sort of worked. I was able to see the UNION, but the parts of the circles inside the rectangle and the 2 lines of the rectangle did not go away as they did in the Basic AutoCAD training.

    It looks like you missed the REGION part, make sure all objects are converted into the region before you use any boolean tool.

    You can type REGION press enter then select all objects and press enter again to convert them into the region.

    I made the rectangle and circle ridged objects using REGION. I then typed INTERSECT on the command line and selected both objects and moved my cursor outside the objects and pressed enter. No visual change. I did note that now my objects were no longer ridged.

      I did not get the “ridged” part? Is there a snapshot you can share?

    Hi. I first diagram shows before REGION command. Second with REGION. The third diagram with the x’s shows that after INTERSECT these lines are still there where as in the training they were removed. Rigid meant the second diagrams view.

      Unfortunately, the image does not seem to be attached as it was large in size, could you please send it to me on [email protected]?

        Intersect tool is working but original objects are not deleting, you can solve this issue using a system variable.

        The system variable is DELOBJ you need to just type this command press enter then type 3 and press enter again.

        Try using REGION again after changing this system variable and it should work now.
