AutoCAD Inventor :: Center Of Gravity On Curved Face Of Assembly
Aug 1, 2013
I am trying to pinpoint the center of gravity on a curved face of an assembly. I can use the c og G command to get the true center of gravity but i would like to incorporate lifting eyes into the finished assembly. Basically I need to know how to find the C of G on a given surface. I have attached the assembly I am working on and added lifting eyes roughly where I would like them. I have tried measuring from the C of G to a face and then creating the lug above the C of G but somehow it doesn't line up.

I have created assembly (lets call it main assembly) in which there are 4 other assemblies (lets call them sub assemblies).
Now in the main assembly document i want to display center of gravity of each of the sub assembly.
When i open each of the sub assemblies and turn on center of gravity of each of them, when returning to main assembly view it displays center of gravity of main assembly, not of each of the sub assemblies.
Im asking for this because i want to create a drawing of main assembly and add dimensions of each of the sub assembly centers of gravity and unfortunatly just as in assembly view, when i want to display center of gravity i can do it only for the main assembly not for each of sub assemblies.

I am trying to retrieve center of gravity in my assembly, I now already coordinates given by iporoperties, now i want to measure to that specific point, is it possible to do it? or to actually show the center of gravity in the assembly?

I'm trying to build a VBA code in inventor 2010 to export the Center of gravity coordinates (X,Y,Z) from an inventor assembly to an excel sheet.
But I'm not able to get the iproperties for the COG from my assembly.

There is any option to merge bottom face of pad eye and pipe curved face... Something like
1. Extrude face to a surface or
2. like notch option available in frame generator ?
N:B - pad eye is made by extrusion and pipe made by frame generator.

I can obtain the Center of Gravity of a sub-assembly. What are the values with respect to? The origin/root of the whole assembly or the origin of the sub-assembly? How can I obtain the coordinate of the COG of a sub-assembly with respect to its origin or with respect to the whole assembly's origin?

How do I get the center of gravity to work, by measuring a distance from the origin like Solidworks? I select the “Physical” Tab under the iProperties “Center of Gravity” and it gives me” lbmass”? Also is there a way for it to show on the screen?

I have a LOD in my assembly to suppress some of the components. In the assembly, it looks like the center of gravity is correct for the LOD. Now I place this assembly in an idw with the LOD active. Now I right-click on the assembly in the idw and choose "Center of Gravity". The center of gravity shown here does not represent the center of gravity for this LOD. The CG shown represents the CG of the master LOD.
Is it possible to get the center of gravity to show on the idw that represent the CG of an LOD?

Structural shape authoring has a parameter mapping for the center of gravity. What values should these be for a C channel where the part origin is at the geometric center and the center of gravity is located along the negative X axis? I checked one of the channels in content center - it had the origin located at the center of gravity and the parameter mapping was the distance to the outer web surface (positive), with the web located in the negative X direction.

How can see visually the center mass of a part or assembly?
When I'm checking in the Iprop., I see the center of gravity coordinates, but it there a way to "see" it (some visual representation)

For some reason it will not let me constrain a part to the center of gravity plains. I would like to constrain lifting lugs to the center of gravity so the model will automatically update itself. Is there anyway to make this work (using ilogic or anything)?
Why would Inventor tease me with showing me the center of gravity plains in an assembly but making them completely useless?

I am currently trying to show a comparison of Center of Gravity between two assembly's. One is the original state and the other has counter weight bars. I know how to get the COG to show on my drawings, but both COG locations are the same in my drawings (but different in my assembly) My problem is when I create View Representations and I toggle the Counter Weight bars off, the COG in my drawing still remains in the same location as if they were still on. I know the hard way of accomplishing my task would be to save 2 seperate models (one with Counter Weights and one without). But I would like to take full advantage of the Representation Option. Using IV 2012 Pro.

I am trying to apply a load lengthwise on a 2 x 2 x 3/16 angle at the center of gravity using "stress analysis" in inventor pro 2014, but it won't let me apply the load at this point. I know that the load would be floating in the air at the center of gravity, could this be the issue?

Ok received parts from a customer. It was ALL mesh features.I converted some of them(the mesh features) to Solids. Some would not convert to solids (converted to surfaces).
I need to have the COG show up correctly. Yes, I have a physical COG. I know where it is supposed to be.
I am trying to use this and several other parts (with mixed, Solids, Surfaces, Mesh features), in an assembly AND balance it all thru a common lift point.
How can I correct the COG of the individual parts, so that the assembly is correct.
I have work planes for the corrected COGs, but I am afraid that I will need to calculate the new COG for the assebmly.

In the iProperties, in the Mass properties are the coordinates of the center of gravity. i guess they relate to the center point and axes in the main origin folder, right?
How can i show and measure from the genter of gravity symbol in parts and drawings?

I have tried just about everything and the mass properties center point of gravity is coming out incorrect.
I have created a box 300x300x300 with the center of the box at 0,0,0 (for testing the cg) . The result I get is not 0,0,0 one of the values always comes out to be not zero, depending on the orientation of the box. Is this a bug?
Dim cg As Point3d = T.MassProperties.CentroidMsgBox(cg.X & vbCr & cg.Y & vbCr & cg.Z)

There are instances where we need to add an extrusion in an assembly (.iam) to show labeling that needs to be done on the floor during assembly.
So we do a new sketch to the face where we need to add the "label", we use text and extrude it 0.001" deep (cut).
On the drawing (.idw) you can see it no problem, but in the model (.iam) itself it's hard to see since the faces that result from the extrusion are the same color as the participant part.
My question is this: Is it possible to change the color of the face of the extrusion?
It's not super important but it would be a good thing to show that detail as we sometimes print a color version of the 3D view for prototyping, troubleshooting, etc.

what im trying to do is select a face in an assembly and create a sketch on it in the part level
this is just one step in the program im trying to make the overall program will create a tube frame and the tubes will be driven from a base solid
Sub test1()
Dim asmDoc As AssemblyDocument
Set asmDoc = ThisApplication.ActiveDocument
Dim asmDef As AssemblyComponentDefinition
Set asmDef = asmDoc.ComponentDefinition

In an assembly document, I try to add a MateConstraint between male and female side of an 45 degrees elbow. The male side is built on the XZ Plane and Y Axis And I try to create a workplane on the female face.
But a got an error with the last line of code. Here's my code (vb.net code) :
' Get application object
Dim app As Inventor.Application = GetObject(, "Inventor.Application")
Dim doc As Inventor.AssemblyDocument = app.ActiveDocument

I was wondering if there is a way to change the appearance of a face in a weldment assembly environment. I have a weldment which in the machining process a part of weld bead as well as a portion of one of the components is machined down (spot faced) and I need to change the appearance of those face to polished, but it doesn't let me do that?

I can't seem to find studs in the Content Center to drop into my assembly. Are they not included?

Why is access to the Content Center only available in the Assembly Environment?
Surely I can't be the only one that could benefit from access to the library when creating a single tube or beam or angle bracket etc..in the part environment.

When my colleague opens one of my assembly's which has content center items in it his inventor cannot find them and vice versa. I am assuming my content center items are coming from my hard drive and not a server from the same place as him. How do you set it up so both our computers take content items from the same location?

A thing I bump in to everytime is that Content Center parts do not standard section in Assemblies and Drawings.
In the Drawings I can menage this by selecting the parts in browser or drawing views and get them sectioned or not.
In Assemblies there is the option to select "Participate in Assembly and Drawing sections" in the Document Settings.
Unfortunately this doesn't work on Content Center parts. Why not?
After searching the site, I noticed the "solution" to check the "Section All Parts" option in the Application options.
This solution is a work around. It only solves the issue when you want to section all parts.
But what if I want to section a few parts and not all?
For example, I do want to section my beams, pipes, tubes etc., but do not want to section my bolts, nuts, washers etc.
I thought that was wat the "Participate in Assembly and Drawing sections" option was for.

I have just installed Inventor 2012 and am experiencing a bizarre problem with placing content center parts. When I start a new assembly, and place a content center part, I would expect it to locate itself central to the assembly origin. What actually happens is that it grounds itself wherever I click on the screen. This doesn't happen with parts that I have created myself.
Is there a bug in the system or maybe an option that I have unknowingly switched off?
