Lesson 9 2D Sketches Angular dimensions Sketch Dimensions Offset

What if your part isn’t 90 degrees?

Angular Dimensions Click on one line Click on 2 nd line creating a corner Enter the Angular Dimension

Sketch Fillet Rounds the vertex created by two lines –Creates a Tangent Arc Specify Radius Keep constrained corners –Maintains the virtual intersection point if the vertex has dimensions or relations. –When cleared, and if the vertex has dimensions or relations, you are asked if you want to delete those geometric relations when the fillet is created.

Offsetting Creates a line a certain distance from an existing line –You can offset more than one line at a time

Extend and Trim Extend a line from one line to another Trim a line

Goal for the Lesson

Lesson 9 Part 1 –Goal: –Fillet is.5” Part 2 –Make 5 copies using the offset command

Lesson 9 Part 3 –Draw a 12” x 6” rectangle centered horizontally and the bottom of the rectangle is.5 below the origin –Extend the Diagonal Lines

Lesson 9 Part 4 Trim lines and fix to black

Lesson 9- Final Extrude

Lab 9 - Handle

Inserting and drawing on Planes Cuts are done perpendicular or normal to the surface the sketch is drawn

Inserting a Plane 1.Click on Right Plane in the feature manager 2.Click on Insert 3.Click on Reference Geometry 4.Click on Plane 5.Enter 4” for the distance to offset from the Right Plane 6.Click on Green Check

Draw the Circle and Extrude Draw a circle and dimension as shown Note that everything is black Extrude the cut

Fillet the Edges Don’t Fillet all the edges

Lab 9 Finish the handle and it to me When your done –Finish the briefcase –Advanced mate

If you are done Create a hinge for your handle Create a pin to go through handle and hinge Assemble your Brief Case
