Sketch.solve()

Introduction

The Sketch.solve() method is a function within the CadQuery library used to solve the constraints and geometries of a sketch. It is used for creating 2D sketches, which can then be turned into solid 3D models.

Syntax

The syntax for Sketch.solve() is as follows:

Sketch.solve()

Parameters

Sketch.solve() does not take any parameters.

Return Value

Sketch.solve() returns a boolean value.

• True is returned if the sketch was successfully solved.
• False is returned if the sketch was unable to be solved due to conflicting constraints.

Description

Constraints are used in 2D sketches to create relationships between lines, arcs, and other geometries. These constraints can be used to create a wide variety of shapes and designs.

The Sketch.solve() method solves the constraints in a sketch, allowing for the creation of the desired geometry. If a sketch has conflicting constraints, Sketch.solve() will return False and the sketch will not be solved. Solving a sketch involves determining the coordinates for all of the lines, arcs, points, and other geometries involved in the sketch.

Example

# create a new sketch
s = cq.Workplane("XY").sketch()
# draw a rectangle
s.rect(10, 20)
# add a horizontal constraint
s.hLine(0).horizontal()
# add a vertical constraint
s.vLine(0).vertical()
# solve the sketch
s.solve()
# turn the sketch into a solid object
solid = s.extrude(5)

In this example, a new sketch is created on the XY plane. A rectangle is drawn, and horizontal and vertical constraints are added. Finally, Sketch.solve() is called to solve the sketch. The sketch is then extruded to create a solid object.

Conclusion

In conclusion, the Sketch.solve() method is an essential part of using the CadQuery library for 2D sketching. By solving the constraints within a sketch, it allows for the creation of complex geometries that can be turned into 3D models.
