AutoCAD Inventor :: FEA And Beam Column Calculator?
Mar 18, 2012
When I try to calculate bending moment stress thru "Beam and column calcultor it shows an error that is Wk and Jk is missing. Ok that is fine. If we put values for both we will get the answer. Because I have come to know thru inv discussion that many material in the CC do not have these values.
Now my question is when we insert a part for example from content centre (CC) and do FEA analysis on this part. It shows some values like deflection, stress etc etc. How is that possible? one side it is not doing in the beam calculatio but other side in FEA it is doing that.
It means we are not going to rely upon these results in the FEA. It is the same CC, same inventor, how should be trust the result in FEA.

I am having trouble using the beam and column calculator in Autodesk Inventor. When I choose the beam that I want to test all the dimensions are not being put in automatically.
This is happening with most types of beams that I import from the CC the angle (6X3-1/2X3/8) that I am trying to test is getting no Wx, Wy, Wk or Jk. and the I beam (W6X25) is not getting Wk and Jk.

I am using beam/column calculator in the frame generator in inventor 2010 suite.I have a beam being used for a flight of stairs it is positioned 40 deg above the 'floor' or my xy plane in my assembly.I want to place a distributed load acting as if there were several people stading on the stairs at one time so in the direction of the z axis of my assembly.
The problem I am having is I try to change the angle of the distributed load but it only allows me to change the x and y components of the load.
a) change the angle of the laod in the Z directions
or
b) change the cordinates in beam itself so the x axis is along the length of the beam instead of the z axis.
I have tried adding a UCS to the beam part but it still wants to choose the length of the beam as the z axis.

I have a problem inserting the slanted columns when I use the "Beam/Column joints" commando. When I insert the slanted column, the beams are divided.
It should look like picture 1, but it always ends up as image 2. How can I solve this?

How can we calculate the formwork of column & beam? Is it possible to add "Height" parameter in Column. Because we add formula into the Family file as below:
Perimeter = (2*Depth+2*Width)
Formwork Area = Perimeter*Height

I am trying to publish to the CC a guide rail. The vendor of the rail gives me the option of entering the desired length of the rail. After that he gives me the option to choose between the length that I entered and a shorter and longer standard length witch can be delivered faster.
I want to do the same thing with my published part, but I cannot make a key parameter to change depending on the entered custom parameter. I want the user to make the next steps when inserting from the CC: 1- select the size of the rail; 2-select the type of the rail; 3- enter the desired length of the rail; 4- choose between the desired length and the 2 recommended lengths (I need these 3 lengths to be shown)
Is this possible?

I have a beam that is simply supported and I am needing to do FEA analysis on it. Simply supported on the ends with a load in the middle. Hand calculations show deflection is 2.256in. FEA shows delfection as 1.247in.
I think the problem is the constraints that I have placed on it. I have one fixed constraints at each end. One of these needs to be fixed and the other needs to be able to move horizontally. How do I set this up to get the correct results?

As i discovered, frame generator is a very handy tool to make a frame, and to connect beams to each other.
For a customer we need to build a large frame, The outer beams are connected directly to each other. The beams inside the outer frame need to have a gap because of mounting and welding.
What i am looking for is a kind of tool, where i can add a notch, and after the notch, shorten the beam with 1 mm at each side to make a gap, which is needed for welding.
Inventor gives an error if i add first a notch followed by a Lengthen/Shorten command. How to add a notch and a gap of 1 mm to a connecting beam?

I have recently drawn a steel construction, and I am now in the process of making the drawings. A problem that occurs is the length of beams used for bracing. When I click the two outer points, the lower dimension in the drawing appears. This is the length of the line between the two points. To be able to dimension properly, I have made a sketch with a straight line, which is perpendicular to one side of the beam. This has been used, with the point on the opposite side, to find the true beam length (and is showed as the upper of the two dimensions in the picture).

Is there a way to display the section property of a T beam? Specifically, I'm looking for the second moment of area in units of in^4 (Ixx). iProperties provide me with the mass moments for the axis in units of lbmass in^2 under the physical tab (global properties). I'm sure this information is somewhere, I just can't seem to locate it. What am I missing?

I'm Alex and I am new to Inventor. We just switched to Invetor From CAD and have been learning as i go mostly. I have been experiencing problems that are leading to major setbacks due to requireing me to redraw multiple items. With my job we have to use wide flange beams and square columns etc..I'm able to draw the indidviual parts and at times have no problem with anything being offset, crooked, skewed or anything. But I find that I'm doing something in the assembly process that is causiing my parts to become skewed/distorted in the assembly and thus also on my view layouts for prints.

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?

Is it possible to make an i part or i feature of the beam end shown in snapshot (every thing except back to back channels) i.e., couples of holes at certain distance attached with some plates etc, so that it can be populated to identical locations.

I have created a block which contains various part numbers, with a description and some other bla bla, with a total number box, I issue this to clients to make the specification of product much easier. My idea was for people to use the quick select command to find how many instances there is of an object within the drawing.
As this is a slightly tedious process, as you have to physically type the part number then mentally take one instance off as it counts the number in the legend block as well.
Is there an addition/summary of object instances command I could use to make this process more dynamic and straightforward for the recipient/user of the block I issue?

Is it possible to have a column in the BOM but i do not want to show it on the drg.
like you can do it for rows for example...

I need to add a custom column to a parts list and have it display as the last column.
oPartsList.PartsListColumns.Add (kCustomProperty)
This code runs, but nothing happens...no error...no column..

Is there a way to customize the BOM columns so that Inventor remembers which columns I need? I know that I can add in the file name column etc. but I use the same columns over and over. I find myself in every assembly adding these columns in.

I have written code to allow me to pick the dimensions of a part and update the dimension parameter name from a list of choices presented in a form e.g. length, width, thickness, outer_diameter, wall etc.
The parameters are exported and I can get overall sizes in the BOM with relevant expressions in columns. So far so good.
What I would like to do is have a global SIZE column in the BOM which has expressions that vary based on another custom iproperty (PartType) which defines the part. So for example if the PartType was 'circular plate' the expression in that parts row of the SIZE column would be <outer_diameter>x<Thickness> while if the PartType was 'tube' the expression in the that parts row would be <Outer Diameter>x<Wall>x<Length> etc
If I could do this I would not need different columns to define the sizes of every different type of material we use and also limit the number of parameters the user needs to choose from when picking part dimensions.
However looking at the BOM API I do not see an obvious way to alter the expressions.

I have a BOM that shows up as in units for length items and unitless for qty items. When I change the UOM to use FT units the non-length units get inch ticks. The qty 1 which means I need one shows up as 1" where I do not require a 1 inch part but one each. How do I remove the inch ticks?

I'm detailing an iPart. Only two dimensions need to be included in the table. One is the driving dimension and the second is a function of the driving dimension. How do I get the column for the second dimension to display a value, rather than an equation?

I need to count the number of pixels in the white part of a person's eye. Is there a way to:
(1) Use a tool (lasso?) to select only the eye white? (an area that includes all color within a certain amount of color variation?) (Choose all the white pixels, and the slightly off-white ones surrounding the white area. The image is black and white, so color variation is solely along the white-black continuum.)
(2) Calculate the area (i.e. in pixels) of the selected area?

I've seen things about getting the information from the parts in the BOM list, but not about seeing what is present in the structure itself

In five years using Inventor I've never seen this- I can't get it the parts list or BOM to register the quantities. Each box comes up with "Unknown Error" and it will not allow manual override to update those quantities.

I have copied a standard "L" to my custom library. Now I would like to map the properties for the CC parts to be like my other parts that are not created in CC. One of the things I need is the "Title" and "Description" iproperty fields need to be the sectional size, i.e. L3x2x3/16, L4x4x3/8....etc.
To do this, I went into the editor and created a column. I mapped this column to Project.Description (see image)
why this does not work? When I create a new part and look at the BOM, I only see "Angled Steel" in the description iproperty field (see image below)
I did the same thing with the "Title" field and the "Project" field. Those work great.... just can't make teh Description field happen.
This is with Inventor 2011.

I have a program that create a bunch of new custom Iprop in each part of an assembly.
How can I show all those new properties when I open the BOM in the assembly file. Manually I can add a custom column but that is time consuming. Is there a way I can create a macro that will add those custom column in the BOM view?
