Surfacing help! 1

[Pand3mic]

Hi

I am new to surfacing in Solid Edge and am having a few difficulties with my current design. I have looked through various tutorials online but have not any success with my own design.

Basically my problem is as follows:
When i added a surface to the sketch, i chose an intersection point between the two curves on the vertical planes. I clicked the intersection point and then the oval shape on the horizontal plane. I then chose my guidlines. I got some type of surface but i fail to get my desired surface.

I have attached the sketch pictures below to show where i am going wrong (hopefully they will explain what i am trying to do better than description of the problem!).

I have also attached the .par file. I added a thickness to this since Solid Edge would not allow me to save it as a surface.

I would appreciate any help ye might be able to offer.

Try this - I couldn't open your part but it's a similar shape.

You will need to un-suppress features.

Thanks for the response beachcomber, it has helped me out some bit.

I have 3 questions:

1) I had a look at your part and i am trying to figure out your steps when you did the BlueSurf. For instance what point did you start with, cross-scetion chosen etc? I tried recreating the BlueSurf but no matter from what point i start from, i am always missing a section when i choose the final guide curve. I attached an image of my step process.

2) Is it possible to add multiple cross-section curves as i need the rear of the surface more bulbous and round?

3) I see you did half a sketch and mirrored it. Is it easier to surface doing this?

Thanks again.

1. Top and Right plane sketches are cross-sections which you pick first.
Front plane sketch is a guide curve.
2. Yes you can add cross-sections, just step back into the command and you should be able to do it.
3. I find it easier to work on half section, but you can sometimes get a slight tangency mis-match at
the joint line - it depends how accurate you need the result.

Try reversing what I did - use the top and right sketches as guide curves.
Your cross-sections would then be end point of one of those sketches, outer curve of front sketch, end point of top/right sketch, then top and right sketches as guide curves.

It will depend on how well you can define your sections, and which is easiest to define.
Sometimes you just need to play with a few simple curves to get used to working with blue-surf.

Thanks again beachcomber.
I played around with it and did as you said and it worked perfectly!

I will try to find more tutorials to try to improve my surfacing. Cheers.
