Question
Hi
Suppose that I have drawn a cubic solid which contains a hole!. Now, how can I show thw hidden lines(correspounding to the hole) in front view or other view ports?
thanks

Answer
This is a misconception in the Autocad platform, its just wasn't built for that. However, a workaround that is to create profiles of each of the corresponding ortho views. Use the SOLPROF command to create a 2D drawing from a 3D solid.

  1. Rotate the solid model to the view that you want to project.
  2. Select a layout tab.
  3. In the Page Setup - Layout dialog box, select the settings you want.
  4. Click OK to set tilemode to 0 and create a layout viewport.
  5. Click the Paper button on the status bar to open the viewport in model space.
  6. Enter solprof on the command line, then select the solid model. Press ENTER to continue the command.
  7. At the Display Hidden Profile Lines on Separate Layer prompt, enter Y. A layer named PH-XX is created (where XX equals the Handle of the layout viewport). Visible profile lines will be placed on layer PV-XX.
  8. At the Project Profile Lines onto a Plane prompt, enter Y. A 2D profile is created. If you answered No, it creates a 3D profile.
  9. At the Delete Tangential Edges prompt, enter Y. (This conforms to conventional drafting standards.)

You can now use layer controls to freeze the solid model in the current viewport and select color and linetype options for the visible and hidden profile objects. Hope this helps, let me know!
