Entities

Entities are items such as lines, circles or arcs drawn by the user or automatically generated by groups.

This list only includes entities that can be drawn by the user.

Entities can either be in a workplane, i.e. in 2D space or in 3D space. Entities in a workplane can only be created if the current group has an active workplane.

All entities can either be construction or normal entities. Construction entities are ignored when finding closed paths for creating the solid model. Construction entities are only visible if they’re in the currently active group.

2D Line

A line in a workplane defined by its start and end point. It thus adds 4 degrees of freedom.

In Workplane:

yes

Tool:

Draw contour, Draw line in workplane

2D Arc

An arc in a workplane defined by its start, end and center points. For each arc, there’s an implicit constraint that constrains the center point to have the same distance from both ends. It adds 5 degrees of freedom.

An arc with coincident start and end point is a full circle.

In Workplane:

yes

Tool:

Draw contour, Draw arc in workplane

2D Circle

A circle in a workplane defined by its center point and radius. It adds three degrees of freedom.

In Workplane:

yes

Tool:

Draw circle in workplane

3D Line

A line in 3D space defined by its start and end point. It thus adds 6 degrees of freedom.

In Workplane:

no

Tool:

Draw line in 3D

Workplane

A workplane defines a local 2D coordinate system using an origin point and a rotation in 3D space. It adds 6 degrees of freedom: 3 translational and 3 rotational.

Use the “Constrain workplane normal”, “Constrain same orientation” or “Lock rotation” tools to constrain the rotational degrees of freedom.

A workplane’s size and name can be changed in the “Selection” tab after selecting it.

In Workplane:

no

Tool:

Draw workplane

STEP model

Geometry imported from a STEP file. STEP import for more details.

In Workplane:

no

Tool:

Import STEP

2D Point

A point in a workplane defined by its location. It thus adds 2 degrees of freedom.

In Workplane:

yes

Tool:

Draw point in workplane
