Make Segment Parallel to Reference Plane

	This task shows you how to make a segment of a run parallel to a reference plane. See also Position a Segment Relative to Plane.
	You can place the offset plane on a surface to make it the reference plane, and then make a segment of a run parallel to the reference plane. In the illustration below, a reference plane will be placed on a face of the item reservation, and a segment made parallel to it. This method does not update adjacent segments. Another method, also described below, updates adjacent segments.
	1.	Click on the `Offset Plane` button and then on the face where you want to place it. A square shows on the face.
	2.	Bring up the `Definition` dialog box for the run.
	3.	Bring up the Definition dialog box again, this time for the segment half you are interested in. See note below.
	Each segment is divided into two halves, which become visible when you bring up the Definition dialog box for the run. It is important to select the segment half correctly because the segment will pivot at the node closest to the segment half you select.
	4.	Click on the `Reference Plane` button in the Segment Definition dialog box. The segment will pivot - at the node closest to the segment half you selected - to become parallel with the reference plane. In the illustration above, the portion in red was the segment half selected. If the half to the left of it had been selected then the segment would have pivoted at the node to the left of it, as shown below.
	5.	Click `OK` and then `OK` again in the `Definition` dialog box.
		`Make Segment Parallel and Update Adjacent Segments` The method described below makes a segment parallel to a reference plane, but also updates the direction of adjacent segments. The user wants to make the tope segment in the image below parallel to the reference placed on the item reservation.
		Bring up the `Definition` dialog box for the run, then right-click on the segment you want to adjust and, in the menu that appears, select `Offset` `Segment`. The `Offset` `Segment` dialog box displays.
		Select the options `Make segment parallel to reference plane` and `Update adjacent segments direction`. The image below shows the result you will get - the direction of the adjacent segments will be modified.
		If you do not use the option `Update adjacent segments direction`then the direction of the adjacent segments will not change, and instead the length of the top segment will be modified.
