Tools

Tools in CAD Sketcher are either exposed as a workspacetool or as an operator. Note however that either of those use the same interaction system.

Generic Tools

`View3D_OT_slvs_add_sketch`

Add a sketch

`View3D_OT_slvs_delete_entity`

Delete selected sketch geometry

`View3D_OT_slvs_delete_constraint`

Delete constraint by type and index

Workspacetools

Workspacetools are used to interactively create entities. You can access them from the viewport's "T"-panel. Check the tools section to get familiar with the behavior of CAD Sketcher tools.

INFO: Interaction with extension geometry is only possible when one of the extension tools is active.

Workspacetool Access Keymap

Whenever one of the extension's tools is active the tool access keymap allows to quickly switch between the different tools.

Key	Modifier	Action
ESC	-	Activate Tool: Select
P	-	Invoke Tool: Add Point 2D
L	-	Invoke Tool: Add Line 2D
C	-	Invoke Tool: Add Circle
A	-	Invoke Tool: Add Arc
R	-	Invoke Tool: Add Rectangle
S	-	Invoke Tool: Add Sketch
Y	-	Invoke Tool: Trim

Dimensional Constraints:

Key	Modifier	Action
D	Alt	Distance
V	Alt	Vertical Distance
H	Alt	Horizontal Distance
A	Alt	Angle
O	Alt	Diameter
R	Alt	Radius

Geometric Constraints:

Key	Modifier	Action
C	Shift	Coincident
V	Shift	Vertical
H	Shift	Horizontal
E	Shift	Equal
P	Shift	Parallel
N	Shift	Perpendicular
T	Shift	Tangent
M	Shift	Midpoint
R	Shift	Ratio

Basic Tool Keymap

The basic tool interaction is consistent between tools.

Key	Modifier	Action
Tab	-	Jump to next tool state or property substate when in numerical edit
0-9 / (-)	-	Activate numeric edit
Enter / Lmb	-	Verify the operation
Esc / Rmb	-	Cancel the operation

While numeric edit is active

Key	Modifier	Action
Tab	-	Jump to next tool property substate
0-9	-	Activate numeric edit
Minus(-)	-	Toggle between positive and negative values

Selection tools

`View3D_OT_slvs_select`

Select an entity

Either the entity specified by the index property or the hovered index if the index property is not set

`View3D_OT_slvs_select_all`

Select / Deselect all entities

`View3D_OT_slvs_select_invert`

Invert entities selection

`View3D_OT_slvs_select_extend`

Select neighbour entities

`View3D_OT_slvs_select_extend_all`

Select neighbour entities

Keymap:

Key	Modifier	Action
LMB	-	Toggle Select
ESC	-	Deselect All
I	Ctrl	Inverse selection
E	Ctrl	Extend selection in chain
E	Ctrl+Shift	Select full chain

INFO: LMB in empty space will also deselect all.

INFO: Chain selection works with coincident constraints too

`View3D_OT_slvs_add_point2d`

Add a point to the active sketch

`View3D_OT_slvs_add_line2d`

Add a line to the active sketch

`View3D_OT_slvs_add_circle2d`

Add a circle to the active sketch

`View3D_OT_slvs_add_arc2d`

Add an arc to the active sketch

`View3D_OT_slvs_add_rectangle`

Add a rectangle to the active sketch

`View3D_OT_slvs_trim`

Trim segment to its closest intersections

Workplane tools

A workplane is any Blender object whose transform defines the sketch plane (see code documentation). These operators manage the workplane an active sketch is anchored to.

`View3D_OT_slvs_align_workplane_cursor`

Align workplane to the 3D Cursor

`View3D_OT_slvs_make_workplane_free`

Detach this workplane from its mesh face and keep it where it is

`View3D_OT_slvs_reattach_workplane`

Click a mesh face to re-anchor this workplane to it
