Inventor Drawing Density Display Format

paul — Tue, 14 Feb 2017 21:13:30 GMT

Hello Everyone,

Is there anyway i can change the density reading on an inventor from gram/cm cubed to lb/ft cubed.

Thanks for you time and efforts,

Paul -

Hey Paul,

These are your only options under Tools>Document Settings

This will translate into your drawing if you push the mass into a text note within your drawing.

If you absolutely need those units, iLogic would be your only other option.

Or if you like something that was said and it was helpful, Kudos are appreciated. Thanks!!!!

So is there no i could like hide the g/cm cubed and multiply the resultant to convert. When setting up the material i punched in pounds per cubic ft, where does that stay. By the way, i do not have the ability to set UM in the the document settings for density...

Please let me know on your thoughts, thanks for your time,

That setting is in the model under document settings. When you insert your views it will become linked to your drawing.

That is why I suggested iLogic for the other part of your comment. I am not a guru when it comes to iLogic, but this is a programming language for Inventor that allows you to do things outside of the general scope of the software.

Checkout this link and see if it helps you.

There is no density inside the document settings...

who could help setting up an ilogic rule?

I saw you wanted to change the units of the density. The only place to change the units is where I showed you. The density is controlled in the material. In my last posting, I gave you a link that might help you with the iLogic.

Hi paul,

The Density setting is part of the Materials, and would be set in the materials library editor versus in the document.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

Hello Curtis,

I can change the density, but i need to can the way it displays in the drawing/or on the sheet... Any idea on how i could do this?

Thanks,

Where can I set to display a density unit of measure? it is not even on the document settings window.

Please help me out on this, thanks,

Paul

Inventor won't do what you want out-of-the-box. You have to do some custom programming in iLogic.

See http://help.autodesk.com/view/INVNTOR/2014/ENU/?guid=GUID-BEBDED71-ED75-4329-ADBA-2E5DDCCF8DE8 for some iLogic background

My reseller tech support gave me this code a few years ago. I run it as an external rule, so I only add it to specific files. I could have added it to my template files, but I did not want to bog down 1000s of components in a large assembly with something I only need in a few components.

Add this code as an iLogic rule to create a new custom iProperty that stores the material density in lb/ft^3. Set the rule to run on any geometry change.

Display the new iproperty on your drawing as needed.

Code Starts:

Density_in_lbs_ft_cubed = Round((ThisDoc.Document.ComponentDefinition.Material.Density*62.427960841), 0)
iProperties.Value("Custom", "DENSITY_IN_LBS_PER_FT_CUBED") = Density_in_lbs_ft_cubed & " lbs/ft^3 "

Code Ends

Hello,

Could you give me step by step direction on where to paste this code, i have tried several instances and nothing seems to do anything,

Please see what you can do, thanks,

Paul

if i change the density with this ilogic rule, should the weight change??? or just the value of measure??? it seems that only the density changes??

Should it not take the volume and change the Mass???

Thanks for your time,

Re: Inventor Drawing Density Display Format

swalton — Wed, 22 Feb 2017 19:26:37 GMT

Nope.

The actual density of the part is controlled as follows:

1. From the assigned material (not appearance).

2. If the user overwrites the mass or volume of the part in the iProperties window, Inventor will calculate a new density based on the part's current mass and volume.

This rule takes the internal density value (from either method), multiplies it by a conversion factor to display lb/ft^3, and stores the result in a custom iProperty. The user can then display that iProperty (with units) on a drawing, in a BOM or Parts List, or use it in additional calculations.
