Sketching in SOLIDWORKS

When creating a new part document, a sketch is typically the starting point, serving as the basis for the 3D model.
Sketches can be created on any of the default planes (Front, Top, Right), a created plane, or a part face.
Sketch Creation Steps:
- Click Sketch on the Sketch toolbar, or Insert > Sketch.
- Select a sketch entity tool (line, rectangle, etc.) from the Sketch toolbar.
- Choose a plane (Front, Top, Right) or a part face.
- Create a sketch using the selected tool.
- Dimension the sketch entities.
- Exit Sketch mode using the Exit Sketch button on the Sketch toolbar, or Exit Sketch/Cancel in the Confirmation Corner.
Sketch Modes:
- Click-Drag: Initiated by dragging the pointer after clicking the first point.
- Click-Click: Requires clicking the first point and releasing the pointer before clicking the second point.

Sketching Lines

A line can be drawn by dragging the pointer.
The line can be modified using the Line Properties PropertyManager or Smart Dimension.

Sketching Rectangles

There are six types of rectangles: Corner, Center, 3 Point Corner, 3 Point Center, Parallelogram.
A Corner Rectangle is sketched by clicking and dragging the pointer.
Rectangle dimensions can be modified using Smart Dimension.

Sketching Circles

The two types of circles are: Circle, Perimeter Circle.
A Circle is sketched by clicking the center point and dragging the pointer to set the radius.
Circle dimensions can be modified using PropertyManager or Smart Dimension.

Sketching Arcs

There are three types of arcs: Center Point Arc, Tangent Arc, 3 Point Arc.
A Center Point Arc is sketched by clicking the center point, dragging to set the radius and angle, and then clicking to set the start and end points.
A Tangent Arc is sketched by clicking on the end point of a line, arc, ellipse, or spline and dragging the arc to the desired shape.
A 3 Point Arc is sketched by clicking to set the start and end points, dragging to set the radius, and then clicking to set the arc.
Arc dimensions can be modified using the PropertyManager or Smart Dimension.

Sketching Ellipses

There are two types of ellipses: Ellipse, Partial Ellipse.
An Ellipse is sketched by clicking the center point and dragging the cursor to set the major and minor axes.
Ellipse dimensions can be modified using the PropertyManager.

Sketching Polygons

Equilateral polygons with 3 to 40 sides can be created using the Polygon tool.
A polygon is created by clicking the center point, dragging the pointer, and clicking to set the dimensions.
Polygon dimensions can be modified using the PropertyManager.

Sketching Text

Text can be sketched by selecting an edge, curve, sketch, or sketch segment, and then selecting Fully Define Sketch.
The dimensions can be modified individually.

Relations

Relations establish geometric relationships between sketch entities.
Automatic relations rely on inferencing, pointer display, sketch snaps, and quick snaps.
Relations can be added manually after sketching using the Add Relation tool.

Description of Sketch Relations

Horizontal relation: One or more lines become horizontal.
Vertical relation: One or more lines become vertical.

AlongZ relation: A line becomes normal to the face of a specified plane.
Tangent relation: An arc, ellipse, or spline becomes tangent to a line or arc..
Concentric relation: Two or more arcs share the same center point.
Midpoint relation: A point remains at the midpoint of a line.
Intersection relation: A point remains at the intersection of two lines.
Coincident relation: A point lies on a line, arc, or ellipse.
Equal relation: Two or more lines or arcs are equal.
Equal Curvature relation: The radius of curvature and vector of two splines match.
Symmetric relation: Two points, lines, arcs, or ellipses remain equidistant from a centerline.
Fix relation: The entity’s size and location is fixed.
Pierce relation: A sketch point becomes coincident to where an axis, edge, line, or spline pierces the sketch plane.
On Edge relation: Edges of a solid are projected onto the sketch plane.
On Surface relation: Sketch entities reside on a surface.
