Create a profile matchline
After creating your workplanes and profiles:
1. Click Modeling and then, in the Model group, click More.
2. Click Create ML in Basic Loft section.
3. Click a vertex on one of the end profiles.
4. Click the corresponding vertices on the other profiles.
5. When all the profiles are connected by the matchline, click .
In the following figure, vertex 1 in the one profile is joined to vertex 1' in the other profile, producing a matchline. The part will have a different shape depending on which vertices are joined, as shown below.
You now have the minimum information for a loft. You can create the loft or add tangent conditions. If you have more than one profile for each workplane, you must connect each of the profiles.
* 
All profiles must have the same number of vertices. You can use the Split operation in the Create 2D menu to add vertices to a profile.
Creo Elements/Direct Modeling uses the matchline to automatically create a workplane set containing the workplanes joined by the matchline. You can manipulate this workplane set.
