When you are modifying a sketch, you can implement your changes by modifying a dimension, by moving selected vertices, or by trimming, extending, or breaking edges. When you move vertices, ABAQUS/CAE also updates any connecting edges that exist between the new vertex locations and unchanged vertices in the sketch, as shown in Figure 19–14. ABAQUS/CAE provides the following methods for moving selected vertices:
Translate
You can translate selected vertices by specifying the start and end coordinates of a translation vector. The translation vector can start from any point; however, you may find it more meaningful to start the vector from one of the selected vertices and end it at the vertex's new location. Figure 19–14 shows the selected vertices, the translation vector, and the result of the translation.
Rotate
You can rotate selected vertices by specifying the coordinates of the center of rotation and entering the angle of rotation; a positive angle indicates a counterclockwise rotation. Figure 19–15 shows the selected vertices, the selected center of rotation, and the result of a 90° rotation.
Mirror
You can mirror selected vertices by selecting a straight line in the sketch as the mirror line. Figure 19–16 shows the selected vertices, the mirror line, and the resulting mirrored locations.
The mirror line may be any straight object line or construction line in the sketch.Scale
You can scale selected vertices by specifying a center point and a scale factor. A scale factor less than 1.0 decreases the spacing between the vertices, and a scale factor greater than 1.0 increases the spacing between the vertices. Figure 19–17 shows the selected vertices, the selected center point, and the result for a scale factor of 1.5.
