Partial selection of a curve plus a curve as one

Partial selection of a curve plus a curve as one

Hello,

 

So I have those 5 curves, and I want to make a surface (with surface menu or boundary blend, either way is fine). Problem is surface is not responding to select those 5 curves together, and rightly so due to their positions and they "estimated-by-my-eye" result that it would come out.

 

The closest thing to a solution is to take 2 of those 5 curves, and then use the rest as guides. Which works up to a point BUT...

 

5 curves are not full ones. 3 of the 5, are partial ones, I want to select them from up to a point. Also it is worth noting that those curves are all boundaries of the desired surface. 

 

1. I connect 2 surfaces. One is partial, one is full curve. All fine so far.

2. I add one partial one at the left boundary. Still fine, surface closes in to the desired shape.

3. I have to add 2 curves, as right boundary for the right side. One of which is also partial. Either way, partial or no partial, CREO does not accept 2 curves to be recognised as one and added as boundary or guide curve.

 

(all connections and points are snapped properly)

 

Any idea?

 

Image for better demonstration:

Red is not used and is left out of the partial loop.

Green is selected to create the surface.

Blue is the  guide curves.

I keep the same number for the same curve.

I change the letter when something is left out, from selection. It is still the same curve though.

Thanks in advance.

Hi,

please upload your model.

Note: It seems to me that some curves have tangent connection with others. I guess that is not allowed.

There is no file. I just do tests for educational purposes.

Tangent curves do need to be part of the same side of the surface.

 

To use 4a with 3 you will need to make a copy of 4 trimmed to 3 first.

What if I want to use 4 for something else so I cannot trim it off? Is there any way to duplicate 4 in place, trim it to 3 as suggested? Also after trimming 4 to 3, can I connect 3 and 4? I don't think I have seen such commands in creo.
