**Trick to cause CAD to ignore non coplanar lines when**

Collinear points Points that lie on the same line are called collinear points . If there is no line on which all of the points lie, then they are non collinear points .... If you have four points and they are not on the same plane (not coplanar), then they define a space. So the simplest Platonic solid is a tetrahedron (a four-sided die), which has four corners. So the simplest Platonic solid is a tetrahedron (a four-sided die), which has four corners.

**determine if the points are coplanar.? Yahoo Answers**

Or put another way, "the points P, Q, R and S are collinear". It's a similar idea to coplanar Just as collinear points all lie on a straight line, in the three dimensional world, when a set of points all lie on the same plane, they are called coplanar....(708,#29) Use the scalar triple product to show that the vectors a = 2i + 3j+ k, b = i - j, c = 7i + 3j + 2k are coplanar, that is, they lie in the same plane.

17/09/2010Â Â· Best Answer: Pick three of the points and form a triangle with them, they are coplanar so this defines a plane. You want to know if the fourth point lies in this plane or not. This is a very standard procedure using vectors; I recall there is a formula for determining the minimum distance of a point â€¦ how to effectively use interpersonal skills in a sentence ogolee 0 points 1 point 2 points 3 years ago First set 'OSNAPZ' to 1, then circle ttr, trim at the lines and reset 'OSNAPZ' TO 0. OSNAPZ=1 tells acad to ignore the z coordinates.. How to search in baretail

## How To Tell If Points Are Coplanar

### If the dot product is zero, the 4 points are coplanar (because a dot product of zero implies that the angle between two vectors is 90 degrees - and thus D is coplanar to A, B, and C). Dot product Cross product

- 24/03/2013Â Â· Hello- " the shortcoming is that it should also accept points as input." Two points in space will always be coplanar, in a meaningless way. If you want to know whether two points are the same distance from a given plane, say the CPlane, then that is a completely different question to ask.
- 26/02/2010Â Â· I also thought a region has to be coplanar - it doesn't have to be in the x-y plane but all in the same plane. Any 3 points will be all in a single plane. Any 3 points will be all in a single plane. In vba i don't know if you can create a region from 'entmake' (or its equivalent in vba), but you could send an AutoCAD command to create it.
- 7/04/2006Â Â· Does anyone know if there is a way to convert two lines that are non coplanar to the same plane? I previously took some surveying points and imported them to AutoCAD.
