You can extend a curve by selecting an vertex on the edge, or an edge.
To open Extend Curve:
Click Extend Curve (Geometry Tools toolbar) or click Geometry, Geometry Tools, Extend Curve.
In the dialog , select the type you want to extend curve:
1. Select the Stop Condition
Distance. Extends the curve by the value you specify in Length
Up to face . Extends the curve to the face selected in the graphics area for Face
Up to edge . Extends the curve to the edge selected in the graphics area for Edge
2. Select the extension type
Linear. Extends the curve along the tangent direction in the original vertex on the curve.
Same Curve . Extends the curve along the geometry of the curve. Such as ciruclar arc extends along the circle, elliptical arc extends along the ellipse.
Extend on Face . Extends the curve on the face if the curve locates on any face.
a. Extend both ends |
b. Extend on end |
c. Extend to face |
d. Extend to face |
e. Extend linearly |
f. Extend at trim curve(Same Curve) |
g. Curve on surface |
h. Extend curve linearly |
i. Extend curve linearly at the surface (Extend on face) |
