Re: Help making a tubular tower

Hi, Chirbney's model is made with compounds clones and mirrors etc, it is a good way for constructing a model but probably not for FEM. I deleted all those mirrors clones and compound till only the four sweeps were left, I fused them and made an array and now the model is solid, so I hope that FEM works.

I will soon download and try Mario's macro, I did not know that one

Wow, the FEM angle is interesting!

What I'm actually building is the tower for the Launch Escape System (LES) from the Saturn V at 1:22 scale. I intend to 3D print. The structure is even more interesting than what I've hinted at here. There is a ring and several braces.

hi
based to http://stellar-views.com/images/NAA_7005-90-12_U.jpg (Credit : http://stellar-views.com/)

i create a squelette (Draft) create points with Macro_FC_Convert_Lines and after Macro_Connect_And_Sweep pipe rad = 40 mm thickness = 2 mm

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.

Lots of great ideas here. I particularly like the macro Macro_Connect_And_Sweep for connecting points and will be using it in the future.

What I wound up doing was writing a macro of my own to get the 3D locations right for all of my endpoints. Rather than go through the tedium of connecting all those points using the macro given in this thread, I just did my extrusions programmatically. It turned out to be pretty easy when I switched my mindset from mouse drawing to coding.

I also added some posts to the top to help fit my model pieces together for assembly. There are also a couple of steps on the original that let people climb on it, and I may add those in the future.
