Chapter 4 – SketchingCoincident – A point can be constrained so that it lies on a figure.Can be applied to: a point and any sketch figureMidpoint – A point can be constrained so that it is fixed at a line midpoint.Midpoint constraints can be placed automatically as a figure is sketched or aftera figure has been sketched.Can be applied to: a point and a line or arcEqual – Figures can be constrained to be equal in size. Equal constraints can beapplied automatically during sketching or placed manually after a figure has beensketched.Can be applied to: any two or more sketch figuresTangent – Figures can be constrained to be tangent to a curve. Tangentconstraints can be applied automatically during sketching or placed manuallyafter a figure has been sketched.Can be applied to: a curve and a line or two curvesPerpendicular – Lines can be constrained to be perpendicular to other linearentities. Perpendicular constraints can be applied automatically during sketchingor placed manually after a figure has been sketched.Can be applied to: two lines or a line and a circle or circular arcParallel – Lines can be constrained to be parallel to each other. Lines can beconstrained parallel automatically during sketching or can be manuallyconstrained after placement.Can be applied to: at least two lines4.6.2 Manually Applying Sketch ConstraintsTo manually apply a sketch constraint:1 Click the small black arrow on the Sketching toolbar to access theConstraint toolbar, or from the Sketch menu, select Constraints.70
