The Section Plane contex- tual ribbon tab and the shortcut menu contain options for editing section objects and generating section views, as discussed later in this chapter. Picking Two Points to Construct a Section Plane A second method for defi ning a section plane is to pick two points through which the section object passes. The section object is perpendicular to the XY plane of the current UCS. When the command is initiated, pick the fi rst point, which cannot be on a face. See P1 in Figure 14-29. It may be best to turn off the dynamic UCS function or you could end up picking a face as the fi rst point instead of a point. After picking the fi rst point, move the pointer and notice that the section plane rotates about the fi rst point. Next, pick the second point (P2) to defi ne a line that cuts through the model. After the second point is picked, the section object is created. The section plane extends just beyond the edges of the model. Picking Multiple Points to Construct a Section Plane The previous method accepts only two points to construct a single section plane. Using the Draw section option, you can specify multiple points in order to create section plane jogs. A section object drawn in this manner can represent an offset or aligned section plane. As discussed earlier in this chapter, offset and aligned sections are used for objects containing features lying in different planes.
