AutoCAD Inventor :: Beam Is Becoming Skewed / Distorted In Assembly
May 1, 2012
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.

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 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 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 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.

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.

When exporting drawings to PDFs, one computer distorts all text as shown here:
When exporting the exact same file to PDF from any other computer, the text appears correctly as shown here:
All computers are running Inventor 2014. What could cause these results? Can the text settings be customized?

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've got a strange problem with my ViewCube. My screen is showing the world ordinate system as it should in the standard plan view ( X horizontal,Y vertical); however, my ViewCube is skewed to the right about 30° (top view and rotated about 30° right). It is set to orient to the current UCS and the current UCS Is World. If I use the ViewCube to change the setting and orient it as top view orthogonal (north straight up) my view (UCS World) gets twisted left by about (not exactly) 30°.Am I missing something or is this abnormal ViewCube behavior?

I'm looking for the best way to create a separate assembly out of various component parts in an existing assembly so that the whole thing can be placed in an assembly as you would a part, I know it's possible to demote components within an assembly but are there any other methods similar / better ?

We have an iLogic assembly with to parts in it. Maybe to cylindrical parts. The iLogic rules should do the following.
1. Start a Rule after open document.
2. This Rule starts a Rule in the first cylindrical component.
3. This Rule ask the user for a diameter.
4. The assembly gives this new parameter value to the second component
5. Then the assembly calls another rule in the second component to change it with the new parameter
Everything is working fine when the following combinations are taking place:
1. I open up the assembly out of vault or from a local drive or an accessible server drive
2. I insert the assembly as sub assembly in another assembly from a local drive or an accessible server drive
It don't work with the following situation:
- I insert the assembly as sub assembly in another assembly out of vault
Then the user becomes the dialog "Choose a diameter" twice.
I don't know why, but I have the idea it has something to do with the functionality of inventor to insert a component more than once. If you insert a component in an assembly Inventor gives you the opportunity to add more than one occurence after each other.
change that behaviour? Maybe a switch to change that inventor "add more than one occurence" behaviour.

I have encountered a problem with the Tube and Pipe styles.
As you can see, I have a rack assembly with a custom tube and pipe style. A wire as a tube in orange, and a tube support in white. Both have their seperate colorations at a style in the tube and pipe styles editor
When placing the rack assembly into the main assembly, it reverts to the coppor coloration I changed from the original style.
Steps I've taken:
Exported the styles .xml and Imported the styles into the master tubeandpipe.iam
Imported the user created .xml styles into the main assembly file nothing seems to work

I am trying to find the interior volume of an assembly (when am I not?!?!) by subtracting the assembly from a block that surrounds the most of it. Somewhere the assembly has a "leak" and I have been trying to use the Cross Section Analysis to track down where the inside lump is connected to the outside lump to be subtracted. Is there a less time consuming way to dynamically drag a plane across and get cross sectional views?
Even better is there a simple way to animate the analysis plane moving across the block so I can hopefully just watch and pause it when I find a leak?

it is possible to make a constraint that utilized a parameter of a part within the assembly.
For example, if I wanted to use the thickness of a plate, which I defined in the part, could I call that parameter in a constraint?

My assembly has grown (about 50 parts) to where I need to consolodate some parts into subassemblies for reuse and alternate iterations of the basic design.
When I import the original parts into a new assembly, all of the constrains I created are not there of course.
I've tried creating a new empty part and then deriving a new part from the assembly, but I can't add, delete or edit any parts.
I looked at using Shrinkwrap, Substitutes, iParts, Multi-body Parts, and Multiple Solids but I remain confused.
In retrospect, maybe I should have created the subassemblies between the part and assembly stage but I didn't.

I want to be able to control the location/position of a component in an assembly. This is easy enough through the iProperties/Occurrence tab and then adjust the location of the X,Y, and Z offsets. Is this possible using iLogic? I have been unable to find a function to access via iLogic. Ultimately I am trying to translate a component about an axis not a pattern.

I am currently creating a 3D model of a building of a complicated geometry. I managed to do this in AutoCAD 2013 but when I exported the iges file and imported it to AutoCAD Inventor Fusion, I get a lot of skewness. This is particularly so for the cylinders I extruded in AutoCAD 2013.I have been looking at this problem for almost a week already. I have attached the photo of the skewness shown in AutoCAD Inventor Fusion.

Can I select a bunch of parts in an assembly and say "save these pieces as a new assembly"?
It is just such a needed tool but I cant find an easy way to accomplish this.

I have a two part duct fire damper assembly. The IDW has the combined two part assembly, which I know how to turn the CoG on, so that it can be dimensioned. The problem is each piece will more than likely be hoisted separately so I would like to show the CoG for each piece, not the combined master assy.is there a way to do this?

I would like to see if there is a routine that allows my iLogic code to detect if my assembly contains another assembly within it. If my assebly contains assemblies then I don't want "MyRule" to run. Else if it does then I want "MyRule" to run.

My Assembly has two possible positions for my piston.
I would like to show both piston positions (top and bottom) in one drawing file; however, in different drawing views.
I have tried using LOD and Drawing View Representations, but it is my understanding that neither of these are meant to be used in this way.

I'm trying to figure out how to make a skewed corridor region for a bridge project (just one assembly I need to skew) the rest of the corridor is split into regions, the approach slabs and bridge deck assemblies are at about a 30 degree angle to the alignment.

How do I save an image so that it is rotated away from straight up and down. I want to put images on a website at about 45 degree angles, but I can't remember (or find) how to do it. I can rotate it image, of course, but whenever I try to save it, it comes back straight up and down.

I have an editable poly that's a 1D circle (not created from circle tool, detached from another), but when I try to apply the shell modifier, it does not extrude "straight" - instead it's skewed.
The affect pivots only are set like this, so it's not going in the direction of the pivot either..
How do I change the direction of the shell?

I have noticed that in one learning project my Perspective Viewport is completely skewed. Other projects are fine, just this one (so far).
Information:
See image IF01.jpg (below) the ViewCubein the Top Right of the Perspective Viewport is perfectly squared and showing the Left View - yet the Grid and all Objects on and around it are angled incorrectly.
Image IF02.jpg shows the Grid and Objects correctly aligned the way they should be - yet the ViewCube is now all off square!

I'm working in a CMYK workspace on a vector graphic with multiple shapes. The above photo is a portion of the graphic as it appears in Illustrator. There are only three color swatches being used.
When I export the file to a PNG, this is what happens:
The two shapes that make the creases of the hand come out a dull color that looks as though the opacity was lowered. I'm using the exact same color swatch for these two shapes as I am for the other blue areas seen in the photo. I've even tried to retrace the two shapes entirely, but I had the same result. My guess is that it has something to do with the yellow area, but I don't understand why it would be having trouble when the yellow shape in the bottom-left corner functions normally when a blue shape is placed in front of it.
