Extrude the series of profiles to form a one solid model

[Joel_Ocampo]

Hi Guys,

Good day, I am wondering if you can help me to extrude the series of profiles to form a solid model? any help is pretty much appreciated.

Thanks

Instead of extruding, can you loft these section curves? Then Cap Holes to close the ends.

Hi Joseph,

Please see attached files for your reference, I also attached an separate point model and would it be okay to help me to create a loop for a profile? I done it manual by connecting the points and quite painful to do, I am wondering if there is a quicker way?

Thanks

Hi Joseph, I did try to join the curves, loft and it works! thanks , one last item is how to create a loop from those points to create a series of profiles?

Thanks

Where is your GH file? These Rhino files are large with many hidden layers…

Yes, there are better ways to connect points to create section curves. However, it depends on how the points are organized. Same goes for lofting section curves - they must be in sequence.

Looking first at the Rhino file Bridge modeling_Slab Profiles.3dm (section curves created by hand), I see issues:

• the loft looks odd
• the section curves are not closed, as they probably should be?
• sorting section curves in sequence can be more difficult when they are not square to ‘World XY’, though in this case, I selected the curves in sequence as you can see by their colors.

Moving on to the other Rhino file with points (Bridge modeling_Point Series for Profile.3dm), the organizing problem is considerably more complex.

As usual, there is no single best way to solve this. One idea is to rotate all the points (in GH) so they are square with ‘World XY’, which would make sorting and grouping easier.

However, all the code required is likely more complex than a newbie will understand, so I’m reluctant to do it for you. Will think about it.

Not too bad. Section curves are rotated back to original location before lofting.

Thank you very much Joseph, I do appreciate all your efforts here
I will take note of that - works on a square position before going to rotate in the correct orientation,
makes it easier to model.

Kind regards,
Joel

I will take note of that - works on a square position before going to rotate in the correct orientation,

Do you see why I did that? So that the rounded Y components will have the same value for all the points making up each section curve. More here:

How can I reorder and orient lines like this?

When working with sets (or Sort Points), it often pays to round values to a few decimal places (1, 2 or 3) so they aren’t affected by tiny differences. That’s why I added the expression to the pDecon ‘X’ output. I found that pattern in the purple group on the old forum and documented it here: I don’t think much about how it works anymore but have adapted it many times for similar issues.
