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 point. For each arc, there’s an implicit constraint that constrains the center point to have the same distance from both ends. It adds 5 degress 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 with 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
