DoctorDrake Posted January 10, 2013 Posted January 10, 2013 Hi. I have an issue I'd love help with. I am supposed to draft a shop building for work but have never done structural drafting before (I mainly work on Piping and Pressure Vessels.) My biggest problem is that I have no idea where to begin. Also, is there a template somewhere for corrugated sheet metal? I found a couple drawings but nothing I can use. Also, they want to be able to show this drawing in 3D. No idea how to do this on AutoCAD. Inventor would be useful but I would have to start from the ground up. The inventor suite my company has doesn't have ANYTHING as far as components go. If anyone could help me it would be greatly appreciated. Thank you! Drake Quote
ReMark Posted January 10, 2013 Posted January 10, 2013 (edited) I have done 2D and 3D drawings depicting corrugated metal siding and roofing so it's a good bet I have what you need. Do you have a 2D plan view of the building? Do you have an elevations drawn yet? Here is a 2D corrugated panel profile saved in AutoCAD 2000 file format. If would be fairly easy to use it to create siding or roofing in 3D. CorrugatedPanelProfile.dwg Edited January 11, 2013 by ReMark Quote
ReMark Posted January 11, 2013 Posted January 11, 2013 Here is the same profile used to create a 3D panel. I created this as a solid by offsetting the profile and closing off the ends then using the PressPull command to give it some height (it is about 0.03" thick). Had I extruded the single line profile it would have resulted in a surface. Quote
ReMark Posted January 11, 2013 Posted January 11, 2013 Corner of an existing process building showing some of the building's framing (green), part of the steelwork for the interior piperack (cyan), and a support frame (red) for a small decanter. On the backside is a concrete wall with a column and two beams used for an exterior piperack. This was done using plain AutoCAD. All the structural shapes were created by me (no add-on software).

Dadgad Posted January 11, 2013 Posted January 11, 2013 I took the liberty of creating a closed polyline (Extrude command friendly) from the profile that ReMark kindly posted for you. As an Extrusion, you can alter the Length of the extrusion in the Properties or Quick Properties. When the closed Polyline is extruded you will get a 3D Solid. CorrugatedPanelProfile.dwg Quote
DoctorDrake Posted January 11, 2013 Author Posted January 11, 2013 would it be easier to do this in rivet? Quote
DoctorDrake Posted January 11, 2013 Author Posted January 11, 2013 this is the corrugated sheet metal i am looking for Quote
Dadgad Posted January 11, 2013 Posted January 11, 2013 (edited) Here is an extruded 3D model of that profile, as they drew it. It is now 6' long, but by selecting it, and adjusting the height shown in the Quick Properties, of your Properties palette, you can make it whatever length you want it to be. There is also the closed polyline from which I extruded this 3D Solid. I merely copied the polyline from their drawing and offset it by .035 inches, which is pretty much in the midrange of the different thicknesses offered, added 2 closing polylines on the end, then joined them all with PEDIT command. as suggested by ReMark. I also made sure that after joining them the polyline was closed, so as to generate a 3D Solid when extruded. FLEXRIBP4 with 3D model.dwg Edited January 11, 2013 by Dadgad Quote
JD Mather Posted January 11, 2013 Posted January 11, 2013 would it be easier to do this in rivet? What is this "rivet" you speak of? Did you really mean Autodesk Revit? In any case - it will be easiest to do in any CAD program that you actually know how to use. Doesn't sound like you have ever done any 3D. If so, that will be the first step, start learning 3D modeling. Quote
DoctorDrake Posted January 11, 2013 Author Posted January 11, 2013 Sorry. It was late while I was trying to work on this. You're correct JD. I have absolutely no 3D experience at all, other than drawing pressure vessels in Inventor. I am working on it right now and I'll post when its done so you can critique my work. Thanks for the help guys. Quote
ReMark Posted January 11, 2013 Posted January 11, 2013 If you are drawing your pressure vessels using Inventor then I'd used the same program to draw your building. How is it then you have little or no 3D experience if you are using Inventor? I find that odd or do most people fail to utilize that feature? Quote
JD Mather Posted January 11, 2013 Posted January 11, 2013 I have absolutely no 3D experience at all, other than drawing pressure vessels in Inventor. This would be easy using the Frame Generator in Inventor. You would have to create a custom profile for the corregated sheet to add to the Frame Generator library, but that is fairly easy.
