6 Sheet Course: Introduction to Engineering Graphics and Visualization copyright 2009, Georgia Institute of Technology 2/26/10 A Closed Profile needs to be fully constrained with constraints added Adding geometric constraints reduces the number of parametric dimensions that must be added to fully constrain a closed profile. 1. Autodesk Inventor adds many geometric constraints while drawing the closed profile. 2. Delete any geometric constraints mistakenly placed during the drawing of the closed profile. Select line - Highlight - Delete 3. Add additional geometric constraints as required. 4. Add all necessary dimensions to fully constrain the closed profile. 5. Look at the bottom right hand corner to see if your sketch is fully constrained. Always fully constrain your sketches!!
7 Sheet Course: Introduction to Engineering Graphics and Visualization copyright 2009, Georgia Institute of Technology 2/26/10 Autodesk Inventor: Constraint Display (F8) Autodesk Inventor shows “Constraint Icons” to display geometric constraints
