AutoCAD Inventor :: Center Of Gravity On Drawing With Different Parts
Oct 21, 2011
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 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.

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 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 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?

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 am working with several drawings that were created, I believe, using Inventor 2011. I am currently using Inventor 2013. I noticed some views do not show the outlines of custom parts created using Content Center. And it's only some of the parts within the view. The outlines of parts created the same way show up correctly. The B.O.M. structures for the parts are set to Normal. I toyed with the Drawing View Settings' Display Options with no avail. When the Drawing View is set to Hidden Lines Removed, the part doesn't appear at all. When I select the shaded option, the part appears, but there is still no outline.
Along similar lines (no pun intended), sometimes the outline extends beyond the actual part location. For example, a pipe that is 24 inches will show up in the drawing view as 72 inches. When the shaded option is selected, the part appears correctly, but the outline extends beyond the shaded area.

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.

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.

I am trying to replace a custom part - created from a content center part - with a copied part with a different name. (I am using the replace tool in an assembly.) However, Inventor is not replacing the part with the part I pick but rather the content center version of it.

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?

Is there a way to display the density of materials that are assigned to varius parts in the parts list on a drawing? I don't need the mass of the parts I just need the material density to show up next to their respective parts.
For example, if I have a part with [steel mild] material assinged to it (no matter the size) I need a column in the BOM on the drawing to show: 490.684 lbs/ft^3. "Worry when there's something to worry about."

I am just starting to make assembly parts from the content center and have found that for the most it is useful. Unfortunately I have found that when these parts are placed in the assembly and a drawing is make of the assembly the bill of material lists total inches of a structural member rather than quantity of piece parts in the quantity column. Thus a 10" tube shows a QTY. of 100 in. rather than 10 piece parts. I have removed the check to export B_L in the function menu but that does not solve my problem. Is there a way to get this to read quantity of piece parts and not total length of material used?

I'm having problem placing fittings in my piping runs from parts that I have created. When I try to place them in I come up with an error "Place Fitting can only be used on authored parts." Now as I have said I am new to inventor so I have no clue what this means. I know there is a content center that has parts used for piping runs which I have been using but it doesn't have all the parts I need so I have been making them.

I am having a problem with the display of a custom content center part in an IDW. The cc part has been added to a weldment assembly and has 2 preparation holes drilled into it within the assembly. These holes display fine when showing the whole weldment assembly in the IDW but when I add the cc part on it's own it does not show the drilled holes. I understand this is perhaps because the cc part had to be prepared with the holes and these preparations have not carried over on the IDW, is there a way to display preparations in this way for single cc parts ?

I'm working on some plumbing in an assembly and in the past I've inserted all the fittings and pipe into a main assembly. Then created a sub-assembly and moved all those parts into that assembly. However I cannot drag and drop the pipe fittings around in the browser window. So I'm unable to move them to a sub-assembly.
I last remember moving content center parts between assemblies in Inventor 2012 and I'm currently running 2013.

You're code is definitley a great starting point, and will most likely save me a ton of time!
I am currently diving into a small project which should save a lot of time for designers in the end if it pans out.
Issue being resolved:
We use the Vault and have a ton of machines that get re-used from time to time through the Copy Design method. There's obviously some changes that are made from job to job, but the big issue is changing a machine from an Imperial to Metric one. This is the time (and mind) consuming process I'm looking to shorten.
What I have:
Currently I have a code (few tweaks needed but it works) that is run from an upper assembly. This code then cycles through each and every sub assembly and part that exists within it. As it cycles through, it checks for hole features which are tapped, and if it finds one of these instances, changes the thread from Imperial to Metric according to a Hard Coded set of values.
Current Dilema:
What's the point of changing the holes if the designer has to go through the assembly to change the bolts and fasteners anyways?
I've practiced a bit with your code and been able to replace items, the issue is everything must be hard coded in order to do so. My question is:
Is there a way to get the Family from the Part Occurence / Document / Anything related?
I've looked through the API, but have only found that everything related to the Content Center.... is only accessable through the Content Center, and nothing else.
For Example, yes I am able to tell if a part has come from the content center (ie. PartComponentDefinition.IsContentMember), but that's as far as it goes, just a simple Boolean.
There MUST be a way to find out some sort of Content Center information from the direct Part / other related documents. I've looked at the "Replace Content Center Part Sample" provided in the API, but this example hard codes the ContentTreeViewPath as well.
In the end, I don't quite understand the point of hard coding this path with no way to access it through the Part Document. This only creates the need for constant manual change and / or MANY rules to compensate each and every family.

I have some parts published in the Content Center. I need to modify a dimension on some parts. I can edit the family table and modify it. The new dimensions are right. But if I open an assembly which use older versions of the modified parts, when I try to update the Content Center parts, Inventor says all standard parts are up to date. When I insert the modified from the CC, I obtain the old version.
I don't have local versions of the part.
If I insert the part with option "Update standard parts when insert", I have the old version too.
I have already made these modification on other parts with no problem, what is wrong with this part ?
I use Inventor 2010 SP4.

How do you copy content center referanced parts to the model? I would like to render my model in Showcase but the nuts and bolts are missing because they are referenced parts.

I am trying to add color to my content center parts. For example I want all M10 hex head bolts to be red and all M12 hex heads to be blue.
I have My library configured in content center and I take from the "Inventor ANSI" catalog the "Heavy Hex Bolt -Metric" and right click and copy to my library. I switch the sort back to merged view and right click on the "Heavy Hex Bolt - Metric" and select family table. I scroll to the end of the table and insert a new column and set the "Column Name" To "Color" and set the "Column Caption" to "Color" , "Map to Inventor Property:" is set to "Member.Color"
Now going back to the family table I have to enter simple color names like, Red, Green, or Black, I cannot enter names like Water Bubbles, Particle Board, or any of the Inventor Apperance names. If you do you will recive an error on placing the part stating " Unable to create componet"
Futhermore when you click on the Material Column you get a drop down of all the different materials.
Why do I not get a similiar drop down for the colors/apperances?
What is the list of working colors names?

This would be for standard, not custom cc parts. I read that you can save a cc part file as a template with the G_L parameter set as fractions, and then use it to replace the family template in cc, but that doesn't work (or I'm doing it wrong). It worked once, then stopped? I know there has to be a way of doing this.
I tried exporting values from cc as custom iProps, then tried to populate description iProp with these, but that doesn't work.

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.
Currently working with Inventor 2012
