How to extend a surface to another surface to create a wheel arch?

[Maskalex]

Hello. I'm creating a car in Creo Parametric 9.0. I'm currently modeling a wheel arch and need help. I don't know how to connect the arch to another surface. Here's a screenshot to help you understand what I mean:

Can you just use the "EXTEND" Command such that it intersects the other surface and then MERGE the two quilts together?

Where the "Extend" command is located?

Select the edge of the surface to enable the command found in Editing section of ribbon.

Are you familiar with the command search tool?  Click on the Magnifying glass in the upper right and then you can type in commands and creo will run them or if you mouse over them, show you where they are.  It is somewhat context sensitive in that if you are in a drawing it will behave differently than in a part.

Using core surfacing tools, a boundary blend should work. You will be able to control the surface connections with the boundary blend feature. You will likely need this control to get what you want and extend will not allow this control.

You will need to create 3D curves for the long edges of the 4 sided surface. Use the existing edges of the surfaces (green) for one direction and your new curves for the second direction (blue).
