AutoCAD LT :: Structural Analysis Software
Jan 21, 2013
I am trying to find a software package that would allow me to model lightweight steel structures; agricultural style barns (up to 60x100) constructed of bar trusses and columns. I can do hand analysis, but for multiple buildings per month, it would be too time consuming. I prefer something more user friendly than finite element analysis, that would produce a quality analysis report.
I have read some through the Revit summary, but it focuses more on the maximum potential of the program and doesn't describe the minimum level it will perform at; I will never be designing a multi - story steel stadium or warehouse or office park, etc.

I created a structural shape profile for use in a project. It is square tube with radiused corners, very similar to "ANSI/AISC (Rolled Steel) Structural Tubing Square" in the content center, but mine is 1 inch square with 0.065 inch walls.
I've made a chassis out of my custom tubing. When I run a frame analysis on it, I get an error/warning stating that the torsional section modulus is zero, because I didn't fill in the value when I generated the frame. How do I calculate that value?
I've attached the tube that I used to make the structural shape.

How do I get to the settings that control what does and does not show in any given discipline - we need to update the Structural Discipline to show the non-structural walls, and non-structural portions of other walls as halftone.

I would like to know how to go from 2d to 3d on a structural drawing, and be able to get beam sizes and lengths. The boss would like to be able to get a report on the amount of all the diffenet sizes and lengths. We using Autocad2013 with no add on.

I've been working with inventor professionally for about a year now doing piping and vessels for the oil field. This also involves a lot of pipe supports and platforms.
I'm trying to streamline the process right now by coming up with a way to make some adaptive bracing that I can reuse so I don't have to model it over and over. Most of the engineer drawings I get are basically the same; 2d lines for beams with work points for the bracing and typical connection details.
I start with a skeletal model and use frame gen to drop my beams in. But bracing is where I run into difficulty. I get it done but its just tedious and time consuming
Is their a way I can make a reusable adaptive or flexible bracing for this task? Here's some pics of what I've been sinking around with to try and automate this (I haven't found a good solution yet).
1. Created my skeleton
2. Dropped beams in
3. Created bracing template
4. Dropped bracing temp in assembly
5. Constrained it into place
6. used make parts to place the gusset plates into my assembly
7. gusset plates fully parametric
I'd like to have a better process of doing this. Ideally I'd like to drop a whole brace sub-assembly (gussets, brace and bolts) in to the main assembly and constrain to the drawing specified work points and be done with it.

I created a structural member of Pro-Panel II and placed it like a column. This works great, except when I need to trim the excess off at the end of a wall. I tried using a body modifies and it works in model view, but it doesn't in plan view.

I have a friend that is using AutoCad Mechanical which comes with blocks of structural members to insert, she is using Cad 2011. In one drawing if she inserts a channel and say the channel is 8" long, it inserts correctly but in other drawings if she goes to insert the same channel, it insert at 16'-0". Why?????

I've attached a structural member. Is it possible to tag each end individually and have ACA report if it's the high end or low end of the structural member?

I had created a structural member using the structural member wizard. I used many instances of the member in my drawing. However, the thickness of the member needs to be modified. Is there a method to modify the existing custom structural member without creating a new custom structural member?

Using Inventor 11 I wish to create some individual parts using Structural Shapes from the Content Center as the basis for my sketch profile and extrude to length before doing other machining.
Is it possible to do this from the Part environment directly and not use the frame generator?

I want to sweep a I-beam along a 3d sketch to create a conveyor. I will be using different shapes at times so the profile won't always have the same shape, sometimes a small I-beam or a large one or possibly square tubing.
I know I can create the profile and dimension it but is there an easy way to import the profiles from Frame Generator into the sketch or another way without having to create and dimension the sketch? Or is this one of those tasks you just can't avoid?

I have a 3 node Structural Member created that works... Now the next questions... Can you anchor columns at 3 column grid intersections... then draw this 3 node Structural Beam such that it will anchor also... so that... if you adjust the column grid... the columns and the 3 node structural member will adjust accordingly?

Is there a method of extracting XYZ data to use for CNC tube bending from components developed in frame generator ? I know that in routed systems you can export that data, but can the same thing be done with frame generator or any individual bent tube or pipe part?

I am creating a dynamic block to do details for structural framing. Attached is an example that I am stuck on. the widget plan and end plan went pretty good. But when I got to creating a cope on the ends I got stuck. I am attempting to stretch the required cope as you can see in my attached drawing. For some reason I can not get the end line to move with the horizontal cope line.

I am trying to make a custom palette for structural members. "Then, temporarily deactivate the link and change the dimension properties of the tool to 4 x 4 x 4 meters. Next, copy the tool back to the Content Browser. The Content Browser catalog is updated with the new tool properties. Finally, reactivate the link from the Content Browser tool to the AutoCAD Architecture palette."

I ran into a problem with the structural member wizard today. I was making up a bunch of glulams and everything was doing just fine, then all of a sudden the wizard stopped accepting new values for the member depth. No matter what you try to enter, it is rejected and a value of 1'-0" is placed in the field. It will accept new values for both width and lamination depth however. I tried to make a member of another material (steel) just in case it was just the glulams. No luck, they behave the same way, you can't set the beam depth. I also tried restarting ACA, working in a completely new (and clean) file, as well as restarting my computer, it didn't work.
I really don't want to have to go through the repair/reinstall circus if I don't have to.

I want to create frame made out of structural steel. In order to do that Invwentor is giving me no option but to make Layout Sketch (any other way?), which then i should use for inserting members. Now, when i want to creat layout it does not give me an option of assigning it to a work planes i created. It always sketches it in default XY plane. I need to create 3D layout that will follow several work planes i created. I tried selecting any of the other work planes before clicking on layout button but no luck.

knew any structural engineering software that can easily import AutoCAD solids and turn them into a mesh to perform a finite element analysis on them.
I have used SAP2000 and it is a little bit of pain to make complicated non-linear forms as a mesh in AutoCAD and then export them to SAP2000. (I do not believe there is a solid to mesh command in autocad yet, if so that would be very nice).

I have created a few new structural parts that I am in the process of publishing to the content center.
I got one of them in and have it working very well except for one item. If I place this structural piece into an assembly as a stand alone part just selecting the length and the material as the key inputs, it shows the proper length in the part number and the description just fine. If I insert this same structural piece in a skeleton using the frame generator, then the length that shows up in the description is the default one that the part was originally created to. How do I get the length to show up in the frame BOM correctly when parts are created using the frame generator?
This works using the structural members out of the box.

I've got a 3D structural model I'm building and will insert 3D mechanical models that I have previously made. I just xref'd the client survey in such that 0,0,0 on my structural model lines up my drawing with the survey.
However, even with the xref frozen and off, when I go Zoom Extents, I zoom to the extent of the xref when I'd prefer to zoom to the extent of my live drawing. I've xclip'd the reference to only include an area slightly larger than the live dwg I'm working on, but no dice.
I think it's functioning correctly, so how do I do a zoom that takes me to the extent of my live dwg and ignores the size of the xref under it?

In the image below, I need the C channel that the bolts are going through to section but not the nuts and bolts. In application options I have "Section standard parts" set to "Obey browser settings". In the part "document settings" I have the "participate in assembly and drawing sections" option checked, but the C channel will not section and when I right click on it in the drawing browser, the "Section participation" options are greyed out.

We've just started using ACA 2012 and have noticed when importing files created in ACA 2009 that structural members do not display properly. We use the structural column or beam to represent a rainwater or soil pipe and are expecting to see a cut through at the cut plane and nothing else however we are getting a couple of lines that represent the crank in the pipe and I cannot turn them off. I'm sure that a setting has been introduced somewhere however after two weeks of looking I am still in the dark.
I've attached a file created in ACA 2009 that displays the problem in ACA 2012
