Lesson 7 Rectangular Objects

Rectangle Command

Rectangles with Vertices on the Origin Start from the origin End at the origin

Rectangles Centered on the Origin Draw a rectangle around the origin Draw a centerline from upper left to lower right corner Create a midpoint relationship between the origin and the center line –Click on add relation –Click on the line –Click on the origin –Click on Midpoint

Dimension Use Smart dimension –Select one side to specify the side’s length –Select two sides to specify the distance between the two sides You should have a 2”x2” square Make sure the rectangle is black

Extrude Extrude the part 2”

Extrude/Cuts The process is the same as for cutting a circle –Select a face –Draw a 2D sketch Relate to origin Dimension until Black –Extrude Cut

2D Sketch Click on a face –It turns green Draw a rectangle Draw a center line from the upper left to the lower right Create a midpoint relationship between the origin and the center line Dimension the square to 1.5” on each side

Extrude Cut Click Extruded Cut Select Blind End Condition –This means cut a certain distance –Set depth to 1.75” Click on Green check

Lab 7 Create a set of 3 “Cubes” with a.25” thick wall –Each cube will fit inside another –Each edge should have a small fillet Lab7 part 1- (Same as lesson 7) –2”x2”x2” Cube – centered around the origin –The hole is 1.5”x1.5”x1.75” deep Lab7 part 2 –1.5”x1.5”x1.5” Cube –lower left corner is aligned with the origin –3” away vertically –Note: the hole is 1”x1”x1.25”deep –Use the wall thickness to center the sketch for the hole Lab7 cube 3 –1.0”x 1.0” x1.0” Cube –upper left corner is aligned with the origin –3” away horizontally –The hole is.5”x.5”x.75” deep –Use the wall thickness to center the sketch for the hole Part 2 Part 3
