Tutorial: Bracket

Tutorial Bracket

• Chapter 3

2
Feature 1 Extruded Rectangle

• Center rectangle about origin to allow for use of
  symmetry later

3
Feature 2 Construction Plane

• Offset from top surface

4
Feature 3 Extruded Boss
5
Feature 3 (continued)

• We will use the Mirror Entities Command in the
  sketch for this feature

6
Feature 4 Extruded Boss
7
Feature 5 Extruded Boss (Center Rib)
8
Feature 6 Construction Plane
9
Feature 7 - Rib

• The Rib Tool allows this feature to be created
  from a single line

10
Feature 8 Mirrored Rib

• Mirror Tool allows features to be mirrored about
  a plane/face (centering original sketch allows
  the Right Plane to be used as the plane of
  symmetry)

Feature 9 Extruded Cut

Feature 9 (cont.)

• For this sketch, we wake up the center mark of
  a previous feature
• With Circle Tool active, holding the cursor
  momentarily over the circular edge causes the
  center mark to be displayed
• The center mark can then be snapped to

13
Feature 10 Extruded Cut
14
Feature 11 Linear Pattern

• Edges of part define pattern directions

Design Intent Symmetry in Modeling

• Using symmetry is good modeling practice allows
  for easy changes later
• Example if the two small ribs are to be
  modified, then changes to one will be reflected
  in the other
• If a part has planes of symmetry, always plan
  your model so that the plane of symmetry
  coincides with one of the pre-defined planes (in
  this case, the Front Plane is the symmetry plane
  of the part)
