Basically it means that one or more of the Line or Polyline Vertices is/are not at the same elevation as the other verticies. In other words, the the Z Coordinate of the Lines and Polylines are not all at the same level.

## What are lines that are not coplanar?

Lines that are not coplanar and do not intersect are called skew lines. Two planes that do not intersect are called parallel planes.

## How do you flatten z coordinates in AutoCAD?

Use the FLATTEN command to change the Z values of all lines, arcs, and polylines to 0.

- Turn off or freeze any hatch layers with hatch patterns so they are not included in the selection.
- Type FLATTEN at the command line.
- Select all objects and press the Enter key.
- Type N for No when prompted to remove hidden lines.

## Can non coplanar lines intersect?

Any two distinct points are on exactly one line. Any three distinct points that are not colinear are in exactly one plane. If two points on a line lie in a plane, then the line lies in a plane. … Therefore, the premise of two intersecting non-coplanar lines is impossible.

## Can parallel lines be coplanar?

Parallel lines are coplanar (they lie in the same plane) and never intersect. Below is an example of two parallel lines: Parallel lines never ______________________________ each other. … When we draw a pair of parallel lines, we use an arrow mark ( > ) on the lines to show that the lines are parallel.

## What are two coplanar lines?

Two lines in three-dimensional space are coplanar if there is a plane that includes them both. This occurs if the lines are parallel, or if they intersect each other. Two lines that are not coplanar are called skew lines.

## How do you prove coplanar?

If there are three vectors in a 3d-space and their scalar triple product is zero, then these three vectors are coplanar. If there are three vectors in a 3d-space and they are linearly independent, then these three vectors are coplanar.

## How do I flatten everything in AutoCAD?

Tool Set: Drafting tab > Modify panel > Flatten Objects. Menu: Modify > Flatten Objects. FLATTEN creates a 2D representation of selected objects and projects them onto the current viewing plane. FLATTEN results in 2D objects that retain their original layers, linetypes, colors and object types where possible.

## How do I change from isometric to 2d in AutoCAD?
