AutoCAD Inventor :: Using Custom Section Properties In Frame Analysis
Jan 23, 2012
I am busy constructing my own Structural Shapes Library in Inventor 1012.During the Authoring and Publishing step I mapped Cross Section Properties (Ixx, Iyy, Torsional Section Modulus, Torsional Rigidity Modulus etc) to set parameters in my iPart table.
I have noticed that once this part is then used in Frame Generator to create a simple beam and then analyzed with the Frame Analysis tool, the analysis tool uses the geometry of the part to calculate these properties.
Is there a way that I can force Inventor to use the properties in the iPart Tables? I am worried that any errors in creating the cross section geometry will be carried into the Cross Section Properties calculated by Inventor.

I have created a report from a frame analysis of an arrangement of I-Beam steelwork. I need to check that I have placed the nodes in the right order and this is reflected in the results of the report. I have the parent and child nodes connected at the ends of the beams as shown on the attached screen shot. I'm interested to know if the order in which I have selected the nods makes any difference to the results. There a 3 node connection points at each corner section.

I am trying to run a simulation on a 4 layer part that has two base layers of I-beams, a frame I made in the frame generator (below) and a solid sheet on top. I am having some issues with the FEA side and was curios to see if the frame analysis tool would yield the same results as the stress analysis simulation. For the frame generator I saw 4 times the amount of deflection despite using (what I believe) are similar loading and constraints, however now I am unsure if I can trust to run an FEA simulation with a frame generated component. The frame is made up of 2 inch steel box beam with a 0.25 inch wall thickness. For the frame analysis package, I have applied a pressure that equates to a 70 kN load across four different sections of the frame. Supports have been placed under all four corners, with 1 being fixed and the other 3 free to move. For the FEA simulation, I applied a similar pressure by creating 2 inch wide plates and applying the same pressure at the same four points. There are also 2 inch square pads under the four corners of the frame with one edge of one pad being fixed and the bottom of the pads having a frictionless constraint. There are separation contacts between both the pressure plates on top of the frame and the frame as well as between the pads and the frame.
with the frame generator is that all the segments of the frame are bonded together (under contacts) which makes sense since they are welded together. However when I put a sheet on top of the frame, there are 3 contact points created between each beam on the frame and the sheet (one on the face of the frame that is in contact with the sheet and the other two on the rounds of the frame and the sheet, even though the rounds are not actually in contact with the sheet). Either way, I am seeing deflections of less than 0.1 mm when a 70 kN load is applied which I know is not right and just want to know if using a frame generated component is not possible with an FEA simulation.

Having an assembly, modeled in the frame generator, then with some additional parts (ribs, plates, etc) added to the assembly as parts and constrained with assembly constraints.. which is the best way to do a frame analysis with the frame analysis enviroment for considering the all structure (frame generators parts + the additional enforcing parts) ?
The assembly look like for example, to this (modeled in autocad).

When I go to Environments>Frame Analysis, I used to get a menu for Constraints, Loads and other settings (similar to the Stress Analyisis menu). I don't get that now. I can right-click on an existing simulation and add constraints and loads, but I would really like to get the menu back.
I can go to tools>Customize, Toolbars tab and Frame Analysis Panel is there. I can click Show and it will show the panel but it stays up all the time. Not what I want.
I have tried resetting the menu, repair installing Inventor and Reinstalling Inventor, but still not joy. How do I get this back to the original setting so that it comes up when I select Frame Analysis?
This is in 2011.

I understand that in a normal part to apply a load to a face is to make it a UDL (uniformly distributed load) by default. To apply a point load, I was told to create a small sketch and use it to split a face to create, in effect, a small face on which to apply a load, effectively making it a point load.
Now in the frame analysis environment, there is clearly an option for 'force' and one for 'continuous force' which the description clearly describes as a uniformly distributed load. However, when I run the simulation (on a 2m long 100mm x 50mm x 4mm Rectangular hollow beam) with a normal load in the middle of the beam (1m offset); the maximum moment comes out at 500000 Nmm or 500 Nm. By my reckoning the moment should be 1000 Nm as the basic formula for a moment from a point load is M = F*D (Moment = Force * Distance). However, to get 500 Nm, it looks like Inventor is using M = (F*x^2)/2 where x is the midspan of the beam (in this case 1m). .is a normal load in frame analysis the same as a UDL? If so..how to I make it a point load?
There are also some errors stating instability of type 2 at various nodes, I've used both Pinned and Floating constraints at either end of the beam.

I have a question regarding adding a force constraint in the Inventor frame analysis environment. When I add the fixed constraint to the beam the orientation indicator is incorrect - the square indicator being not parallel to the base of the beam. I would like to know why this is and as I am relatively new to frame analysis if I am doing something wrong. I have attached a screen shot of the placement of the constraint on the beam.

I created an extruded aluminium profile (attached file: Item Profile 8 80x80) which I published into the Content Center. When using this profile in a frame design, and using the Trim To Frame command, the profiles are trimmed at a weird angle (attached pdf file).

I am trying to run a Frame analysis on a beam structure. I wanted a specific yield stress for the components that make up the beam. So I created a new material and changed the yield stress and change my beam components to that new material. However when I run the simulation the yield stress is not what I made it. Is this allowed?

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.

I've made a number of frame generated assemblies with standard ISO 30X30X3 L-beams. Now they wanna change it to another dimension still standard just 40X40X4 instead.
I'm pretty new to this but shouldn't I be able to do this for an assemble in one go with frame generator?

In my idw, when I right-click on my section view line (or the section view itself), I want to change the section depth from full to some distance. Problem is there is not a "Edit Section Properties" in the context menu.
There are other section views on this sheet and they will display "Edit Section Properties" in the context menu.
Any clues as to why I dont get a context menu on just this one section view? I could delete the view and redimension everything, but I had rather not.... Its got several dims on it.
Cant post the file either... its pretty large.?The idw itself is 16mb, not counting all the parts/assemblies.

I'm trying to make a drawing of a assembly, and some of the parts were made in frame generator. When I try to make a section view the parts made in frame generator still show as whole instead of halved. Is there something that I need to toggle or vice versa so that this will not happen anymore?

In Solidworks they had something called custom properties that were generally setup in the models where you had the property names and then values would be filled in to automatically populate drawing titleblocks. I found this, but I can't get the drawing description to keep changes and update the drawing.

I'm trying to migrate from AutoCAD into Inventor while maintaining my companies standards - and I need to change the way section marks show.
Is there a way to create a custom section mark routine (in AutoCAD it was a LISP routine) to make section marks as shown in the attached picture?
In the AutoCAD version, it took 3 clicks, and then prompted for text inputs - 1st was the end of the line with the circle, 2nd was the other end of the line, and 3rd was the direction of the section. Then there are 2 text prompts - first the section label, then the sheet humber.
Is this possible to do in Inventor? I figured out how to make the circles with prompted text but can't figure out how to make the lines and arrows to go with it without being fixed length and position.

I want my custom property to defined as item #. That Item # then is represented in the balloon.
reasoning is that then engineers wont have to check drawings anymore for the guess work involved in matching the part balloon to each individual part in the assembly being called out.
I can then focus on creating a BOM that shows the different item#'s and the user can quickly go through it.

I have been working on this previous project "A" and I realized a few custom frame profile such as Bosch Strut and Din rails. Now I am done with project "A" and I am moving onto a new project we are going to call project "B". In this new project "B" I setup all my libraries as I would normally do, but once I start creating frames, I do not see any of the custom frame profile from my past project "A" even though I added my libraries, which are identical from project "A" to "B".

My custom library works fine when I try to insert a part from content center, but when I try to use frame generator my library is not seen. I set the "Standard Organization" and "Standard" family property fields both to "DYNA" hoping that standard would show up in the frame generator "Standard" drop down menu but it doesn't.
I saved a copy of a pipe family to "My Library" and made it an independant family.

I would like to know if there is a way to suppress size in a custom table for frame members. So far, I've copied the ANSI hss square tube library to another name and it is not linked to the previous family. What I need to do is make only certain size of these tubes available and the only way I found was to delete them. The things is I don't want to delete them because I may need them in the future. Also, when I have different materials in that table they appear as 2 diferent size in the frame generator insertion window. For example, if I have in my table a 2x2x1/8 tubing 1 in aluminum and the other in steel, I will have 2x2x1/8 X2 in the size selection window.
