Activity 5.2 Geometric Constraints
Procedure
1. Open the file called
Geometric Constraints
. Read the instructions above each image in the file and use the
Geometric Constraint
tools to complete each of the 12 exercises. Your completed sheet should look similar to the sheet pictured.2. Make the geometric constraints visible by choosing the Show Constraints toolin the Constrain panel under the Sketch tab.3. Add your name to the bottom right corner of the sheet. You may use the Text tool in the Draw panel under the Sketch tab to add text to a sketch.Conclusion
1. What is a geometric constraint?
Geometric constraint is a constant, non-numerical relationship between the parts of a geometric figure
2. What are the different types of geometric constraints that are applied to sketches,and what are their functions?
Perpendicular: constraint that causes lines or axes of curves to meet at right angles
Parallel: two or more lines to be equidistant from each other
Tangent: two arcs or a line an arc to intersect at a single pt perpendicular to the arcs radius
Coincident: fix two points together or fix a curve
Concentric: two or more arcs or circles to share the same center pt
Horizontal: causes lines to lie parallel to the X axis of the sketch
Collinear: two lines or ellipse to lie along the same line
Equal forces: line segments to be the same length and arcs or circles to have the same radius
Vertical: causes lines to lie parallel to the Y axis of the sketch
3.
Define “tangent”.
Tangent: is used to cause two arcs or a ling and an arc to intersect at a single pt perpendicular to the arc's radius
a. Sketch a line tangent to two circles.
Sketch: is a line tangent to two circles.
4. How is a geometric constraint different from a numeric constraint?
a number value or algebraic equation that is used to control the geometric figure. A non number value is used to control the relationship of the parts to the figure.
