Extending a Line to an Existing Entity
Create a line.
The procedure below describes how to extend a new line to an existing entity. The line and the entity become mutually constrained.
Note: If the existing entity is not in the current sketch, you must add it to the sketch as a reference entity.
-
First, create a new line using one of the Line
options (Pt, Parallel, Normal, or Tangent). An image of the line appears. -
Extend the line to an existing entity. The line can be:
-
-
Lying on the perimeter of the entity.
-
Tangent to the entity.
-
Intersecting the entity.
-
Note: If the line has a previous constraint (for example, it is tangent to a circle) then all three entities are constrained.
Extend a new line to lie on or be tangent to another entity
-
Create a new line using any Line option (but do not click to define the entity).
-
Move the cursor to another entity.
-
When the image of the line approaches the entity, the entity changes to dashed purple.
-
-
-
When the image of the line is close to tangency with an entity, the circle or arc changes to dashed cyan.
-
-
-
When the image of the line is intersecting the entity, the entity does not change color.
-
-
Click to place the line relative to the existing entity.
Note: If the new line was placed close to tangency to an entity, or touching an entity, the line will snap to the perimeter of the entity.
