Wow! I can't thank you enough, I didn't know sketchup could do something that complex!

I've tried your method and I now have the surface with mostly regular quads.
I now have to make "pyramids" on top of them in order to have the final space truss to transform into tubes.
I've started to do that on a face but I'm struggling to get the vertical line to the single face in order to than make the four lines that reach the four vertices in order to make the pyramid. Also is there a way to automatically transform all those quad faces into pyramids with a 1 meters by 1 meters base(the one already existing in the mesh) and a 0.5 meters height? I've tried the s4u to component but can't make it work...

Thank you very much for helping!

Space truss.skp

Thank you very much! I'll download and try tomorrow. It's definitely a lot of work but I need it in order to make an architecture collage on photoshop to show a view of the interior and exterior.

Thank you again for helping.
The problem is that i need squares of about 1 meter x 1 meter and I can't seem to get that with curviloft.
Plus with curviloft i get that circle on the top as you've made.
I've also tried to make a plane with the 1x1 meter grid and then curved it so that it would fit my surface but I wasn't able to do it.

Thank you for your answer, I've tried with curviloft but can't seem to make it work. Maybe because I've never used it and didn't understand all the commands from the tutorial.
Here is the .skp file in sketchup8

Space truss.skp

Hello, I'm writing for a problem I'm having trying to make a space structure.
I can't seem to find a solution so here is the problem:
I'm trying to make a space truss similar to the one in the last image, in order to do that I'd need to have a surface made of regular quads (or at least similar to each other as they can be) in order to than use the plugin that converts lines into tubes. The problem is that the surface I have is basically generated from to arcs and another arc which is the direction line. I can do the surface with the extrude to rails plugin but it isn't made of quads.
So my question is, is there a way to make a complex surface as the one i'm trying to make, and have it made of regular quads or at least similar to each other in dimensions? The idea is to have the surface divide into equal parts.

Thanks for helping!

Hi, I've exported a few 2d graphics from sketch up and saved them as .tiff
As long as I look at them from the preview on mac they are fine but when I place them on an illustrator or photoshop file all the lines become dashed and the quality goes down.
How can I solve this?
Here are two images, one from preview and one from illustrator

thank you!

Thank you all, I followed the instructions and was able to make it solid!
Sorry for all these stupid questions but I started using sketchup last week.
I've the last question, how can I hide all the geometry lines on the surfaces of these solid?

Thank you very much! May I ask how you made it solid? With a plugin?
Thanks!

I re-did the whole wall from the start, this time I used the extrudetool plugin instead of bonzai so I didn't need to import/export. Also I scaled the curves 50x up before doing the surfaces.
If I use a section and use add section-cutface 2 parts of wall are solid while the first one is not, I tried a solid solver plugin but didn't work, do you have any suggestion?

Wall.skp

Ok so, what do you suggest?
Should I recreate the curved surfaces making them 50x bigger, than import on sketchup, run an automatic solid-fixing plugin and scale down?

I did those surfaces on bonzai3d and than imported on sketchup because I wasn't able to create the surface from the edges on sketchup. On bonzai3d I simply selected the edges of the area and the surface was created, even if there where curves as edges, is there a plugin that does that directly on sketchup? SO I don't have to import and the mesh won't have errors.

Thank you all for helping. I solved a few issues, i now have what appers to be a solid, still I find a few mistakes, tried to use a few plugins to make it solid but with no success...A plugin told me it can-t become solid.
Isn-t there a plugin or a way to simplify those surfaces impossible to close, in order to make it solid?
Thanks

PS I forgot to mention that there are 2 walls on the file because the more complete one is how I need it to be.

CurvedWallMaison.skp

Thanks but I found a plugin that used the section plan to cut everything above it, I linked all faces but I found the real problem: when I imported not all the meshes where done.
Is there any plugin that creates the surfaces to fill those voids? They are to many to be done one by one with lines manually.

Here is what I meant, I made a section plane and the surfaces left are those I want to keep and than close as a solid. How can I keep just the surfaces uneder the section plane and delete all those connected but above?

Thanks! It was working but, while doing that, I found out that the surfaces arent completely straight, if I draw a surface following green and red axes, over the 2 existing surfaces, one of those goes over the surface I just drawed.
Is there a fast way to delete all the surfaces above? I could delete those one by one but, as you see, there are many lines. I wonder if it's possible delete everything above the surface of the red and green axes, like extruding that surface and deleting everything above it.

Hi, I'm new to sketchup and I'm having problems trying to create a wall from a few curved surfaces.
I created the surfaces on bonzai3d and imported on sketchup. Then joined them all as a group and now I have those 2 2d walls and nothing between them, how can i fill the space and create a solid?
