Open sweep.dwg and save it with a new name of ch43-sweepprob.dwg. Erase the swept solid. Create a new profile by drawing a .5" × 1.5" rectangle on the ground plane. Create a new swept solid using the new rectangle as the profile, and use the Twist option to twist the swept profile 270°. Your drawing should look similar to the one in Fig. 43-13. Save your work.
