    Hi Sunith:
     
    I read your article “Are you parametric Part 2 ” and found it very informative.  I have a related question if you don’t mind:
     
    I would like to include other model parameters (aside from sketch dimensions and extrusion lengths  to name a few) , such as material density, and part volume in a spreadsheet which I have linked to the parameter table.  The problem is, I don’t  know where to find the part density or volume variables or what their names are so I can use them.
     
    Example:  This part will be immersed in oil and I need to calculate the wet weight (i.e. dry weight minus buoyant force)  of this part realtime in the embedded spreadsheet as I alter the geometry.  To do that I need to include the material density and volume (and or weight).  I could program the spreadsheet to calculate volume, but why do that when it’s already done somewhere inside of Inventor and besides can get complicated quickly for some parts ? 
     
    I hope my question is clear enough.
     
    Any guidance or suggestions would be most appreciated.
     
    Thank you very much,

    Dear Mr Tim Kray,

    You can use Auto Limits and or Inventor Ilogic, however iLogic needs you to be a subscription member at Subscription Center from Autodesk,
    ——————————–
    However to add value for your question, I have a reply from one Autodesk Employee (India)
    ——————————–

    There are two ways for approaching this problem.

    Autolimits: Here you can set Dimensional property limits as well as Physical property limits (Volume,mass).

    Eg: I can set some conditions in Autolimits so that my volume or mass should be within some limits.I can then alter the dimensions in real time so that Autolimits can tell me whether my volume is exceeded or within limits.

    Ilogic: Here also you can set physical properties and and find out real time changes .

    Dear Sunith and MSD employee:  Thank you very much for your replies, I will experiment with AutoLimits. 

    However, I need to use mass and other physical property variables directly in the linked spreadsheet calculations.  For example, in the spreadsheet, I would like to calculate the wet weight of a part or assembly:

    Wet Weight = Dry weight (i.e. weight) – part volume x fluid density.   

    To do this, I need to place the weight and volume values in the spreadsheet.  How do I do this ?  One way is to use the clipboard feature in the iproperties / physical tab and paste these values into the spreadsheet, but this requires a manual copy and paste operation and I am trying to automate all calculations.   I guess what I am asking is what are the variable names for physical properties ?  Dimensions have names, such as d3 or L1 and can be used and/or controlled by a spreadsheet, so what is the analog for physical properties ?

    Thank you all again for your replies,

    Tim

    i just want to ask if where or do you have any command lists for parameter formulas  (ex. max, min, round, etc).. i need to know each commands (like from excel) because i have been using formulas for parameter changes like max(d20,5mm/1deg*d15) and etc and also for animation/constraints.

    i hope you can reply soon..
