Construct a line of intersection of two planes
Given: Tables of coordinates of vertices of triangles DEF and STU.
Task: Construct a line of intersection of two planes defined by triangles DEF and STU in 3 projections. Determine their visibility.
We have already solved problems on the intersection of two surfaces given by triangles, here are some of them:
- Intersection of planes - Intersection of two perpendicular planes.
- Crossing of two planes defined by triangles ABC and EDK.
The difference between this problem and the previous ones is that it is necessary to build a profile projection of the planes and determine their visibility. We begin the solution of the problem with the construction of the profile projection of the planes.
The solution of problems on descriptive geometry I produce in the automated design system AutoCAD and AutoCAD 3D. This training will allow you to develop spatial thinking and consolidate the possession of AutoCAD.
