Surface modeling

I have some problem constructing a surface out of an irregular trajectory. As shown in below image, the trajectory is the red-coloured line, the outer profile was constructed with multiple sketch profiles combined at certain datum point. I wanted to create a surface that follow the

I can think of many ways to construct this, however I'll address the things in your post.

You can select the entire red curve by picking the initial segment (as you have done) and then holding "shift" to build a chain of the other segments. I would then add the bottom curve as well, through the lower end points of your cross curves, and build with 3 curves in one direction and 8 in the other.

...or, as I like to do, highlight that curve and go into the "Details" tab below, which allows you to select by rules, intent chain, loop, etc.

I recently modeled a part similar to this where I needed several different sketched sections swept through a trajectory. You might consider using a swept blend feature for this. You should be able to use your existing sketches.

Here's something I whipped up using a swept blend.

Hi..i think that's what I did in the first place. the final blend became very distorted as the 'red-coloured'curve' were sketched with multiple shapes being put together, while the end curve were based only on the end point of the wall (blue-coloured) line.

didn't work. Can't seem to select the curve as complete loop etc.

Here's the preliminary sketch feature that make out the outer line.

Hi... almost got the feature that I wanted. Just wondering if the above figure was constructed out of multiple swept blend function? How about the trajectory? Seems like my trajectory is split up that some region (wall/blue-coloured-line) are not covered by the trajectory...
