1. Create the 3D
model. I worked with one object, but you can work with more than one.
2. Set up the view that
you want.
3. Start the UCS command
and use the New>View option to set the XY plane parallel to the view.
4. Choose a layout tab.
By default, a viewport is created automatically. Otherwise, choose
View>Viewports>New View (MVIEW command) and create a viewport.
5. Double-click inside
the viewport to switch to model space.
6. Type solprof on
the command line. At the prompt, select the 3D model and accept
the defaults (Y each time) for all three prompts. You should now see a
wireframe profile. (The profile is one object.)
7. You’ll now see two
new layers in the Layer Control drop-down list. One starts with PV- and could
be PV-ad, PV-125, or any suffix. The other starts with PH- and has the same
suffix. The PV layer contains the front parts of the profile (V stands for
visible). The PH layer contains the hidden parts (H stands
for hidden). Make the PV- layer the current layer.
8. Freeze all other
layers. Now you see the hidden view. If you want a wireframe, don’t
freeze the PH- layer.
9. Press Ctrl+C and
select all objects (which won’t include the frozen layers) to copy the profile
to the Windows Clipboard.
10. Start a new drawing.
11. Press Ctrl+V to paste
in the profile and specify any point to place it. You should see the profile
looking exactly the same as before. (If the angle looks wrong, reproduce the
viewpoint you had in the previous drawing and set the UCS to View again.)
12. Start the EXPLODE
command (because the profile comes in as a block) and select all objects. (Skip
this step if you want to leave it as one object.)
13. The new profile may
not be the same scale as the original. If not, measure any length
in the original drawing.
14. Use the SCALE command
and select all the objects. Then use the Reference option. At the prompt to
specify the reference length, specify the beginning and end of the length you
measured, that is, the same object in the new drawing.
15. At the prompt to
specify the new length, enter the length that you measured to scale the model
to that new length.
