SOLIDWORK learning notes: Sketch geometric relationships and editing

Hold down ctrl You can select multiple segments at the same time

1 Geometric relations
Select multiple lines at the same time , Click on the toolbar “ parallel ”, These lines can become parallel . Right click （ Or select and press Del） You can delete the created geometric relationship

Selecting a circle and a straight line can realize the tangent geometric relationship

Take the straight line as the construction line , Selecting construction line and two circles can realize symmetrical geometric relationship . Two symmetrical circles are always equal in size , If one size changes, the other will change

2 Sketch clipping
Select the crop solid option . Inside, strong clipping can clip all line segments to their vertices

Press and hold when cutting strongly shift Key to extend the selected line segment

Transforming entities
