The fully dimensioned sketch is shown in Figure 3-3. Adjusting a dimension value changes the associated geometry. After the sketch is drawn, dimensions can be added. Although it is possible to construct precisely, it is not necessary. When line AB was constructed, it was not drawn to the exact length of 170 mm. The sketch in Figure 3-2 was drawn in metric units. Displaying, adding, and deleting constraints are discussed later in this chapter. Constraints can be manually controlled as well. The display of constraints can be turned on and off. The automatic constraint symbols for all six lines are displayed in Figure 3-2.

You can also apply dimensional constraints. Horizontal, perpendicular, coincident, and parallel are all geometric constraints four of the 12 total. By default, Inventor applies parallel and perpendicular constraints whenever possible in place of horizontal and vertical constraints. Constraints deﬁne and maintain the relationships between the geometry in the sketch. Line CD knows that it is parallel to line AB. This is indicated by the small, yellow dots at the ends of both pairs of lines.

Line BC also knows that it is connected (coincident) to lines AB and CD. Line BC knows that it is perpendicular to line AB and the perpendicular symbol is displayed on both lines. The shapes on the left are valid 2D proﬁles for extruding into solids. Sketching, Constraints, and the Base Featureįigure 3-1. Copyright © The Goodheart-Willcox Co., Inc.
