(Obtaining ACIS Solids from existing 2D Drawing Views)

Interactive Project 1 - ACIS Core Solids

You will need Release 13/14 or Mechanical Desktop for this project.

Open the drawing called CORES-1.DWG. This drawing contains several named, preset UCS to streamline your solid construction. In addition, each view that you will need is present in block form.

  1. Set the UCSFOLLOW - UCSFOLLOW - 0 - this prevents the view from "following" the UCS
  2. Set the UCS - UCS - Restore - Top
  3. DDInsert - Block- Top - @ 0,0,0 and Explode
  4. Convert to Closed Polylines - PEDIT - Convert to PLINE - Join (repeat as needed)
  5. Set the UCS - UCS - Restore - Front
  6. DDInsert - Block- Front - @ 0,0,0 and Explode
  7. Convert to Closed Polylines - PEDIT -
  8. Set the UCS- UCS - Restore - RSide
  9. DDInsert- Block- RSide - @ 0,0,0 and Explode
  10. Convert to Closed Polylines- Tip: RSide profile must be edited. Trim the front vertical line at the horizontal intersections, removing the portion in between. PEDIT - Convert to PLINE - Join (repeat as needed)
  11. UCSFollow- 0 (this prevents the view from following the UCS.)
  12. Set the UCS- UCS - World
  13. Set to SW Iso View. (MDT Accelerator Key - 8)
  14. Extrude Top View to Hgt of 10 and RSide to -10.
  15. Interfere (select one extrusion, then the other) Make Interference Solid. Delete RSide and Top solids.
  16. Extrude Front View to Hgt of 10.
  17. Interfere (select front extrusion, then the previous solid) Make Interference Solid. Delete Front solid. Subtract holes. The result is shown below:
