When two lines, rays, or line segments intersect, they have one common point; in this case, the line segments intersect since they … Nettet26. apr. 2011 · You would end up with overlapping lines at the co-incident edge, and you would have created the "short circuit" with the line for the edge where the 2 rectangles are co incident. If you need 2 rectangle objects like this side by side with a co incident edge, you will need to draw the 2 itmes seperatly in Revit.

NettetTo find the intersection of two straight lines: First we need the equations of the two lines. If you do not have the equations, see Equation of a line - slope/intercept form and Equation of a line - point/slope form (If one of the lines is vertical, see the section below). Then, since at the point of intersection, the two equations will have the same values of … NettetGet the dot product of all 4 vertices (the corners of the rectangle) with the direction vector of the line segment. If all 4 have values of the same sign, then all the vertices lie on the same side of the line (not the line segment, but the infinite line) and thus the line does …

The problem is that Rectangle has dimension 2, so the intersection of lin and recis a line and not 2 points.

Nettet20. okt. 2010 · $\begingroup$ @Mike: If the rectangles intersect, their intersection will form a new rectangle (possibly 1-dimensional i.e. line) as long as one of the lines in the first rect. is parallel to a line in the 2nd rect. I don't see how the coordinates of the corners influence this in any way. $\endgroup$ – jericson.
