SectionPlane

Option

Description

Specify start point

Specifies the starting point of a 2D section plane; prompts you:

Specify through point - pick a second point

As you move the cursor, the program ghosts the section plane:

Use entity snaps to make the pick points accurate.

select Face

Select the planar face of a 3D solid; this option does not work with non-planar faces, such as on spheres.

Prompts you:

Select entity - choose a face

The section plane coincides with the selected face. The LiveSection property is turned on automatically. Live sections are sections that can be interactively edited.

Draw

Define the section plane by two or more points; draws L and U-shaped sections planes.

Prompts you:

1. Specify start point - pick the first point or enter x,y,z coordinates; use entity snaps to place the plane accurately
2. Specify next point - pick another point
3. Specify next point or ENTER to finish - pick another point, or else press Enter to stop specifying points
4. Specify the direction of the section entity - pick a point to specify the view direction of the section plane; the side of the section plane you pick is the side that is not cut away.

The section plane is created through the specified points and perpendicular to the current UCS. The Image below shows an L-shape section plane.

Orthographic

Places a section plane entity in one of the six standard drawing orientations, relative to the current UCS is created; prompts you:

Align section to [Front/bAck/Top/Bottom/Left/Right]: <Top> - enter an option

The program draws the orthographic section plane through the center of the bounding box that contains all 3D entities in the drawing. The figure shows the result of the Top section plane:

The Live Section property is turned on automatically.
