can any1 tell me how to measure weight of part in catia using "MEASURE INERTIA" command?

By rahul on 26 Oct 07:09 4 answers 3 comments

i m trying to calculate weight of plastic part in catia using "measure inertia" command...

but whatever result comes & actual weight which i get from weighing instrument is different...

the difference between actual & catia computed weight is much...

help me to solve it..

whether i have to apply material n then use measure command or is it ok to just changing density in measure dialog box???

    You must type the density value in the dialog box, but when you use this function, klick on the part body, and not od the part in the tree. If you klick on the part it will calculate all bodies in this part, and surfaces in your geometrical sets.

    Wing span- 700mm
    Root chord - 100mm
    Tip chord - 40mm
    Aspect ratio - 10
    Taper ratio - 0.4
    Wing area - 49,000

    please check the material properties before going to add.we have taken the above parameters...but some dimensional and geometry error we found the calculated weight and part weight was 3% error.

    Give Density for measuring the weight if whole product made of single material.

    If there are different objects with different material giving material properties is advisable. Otherwise you have to measure weight individually & add at last.

    But note that when you using measure inertia tool, it measure the weight of all bodies & parts which are hidden or shown. So, if u don't want weight of hidden parts please deactivate it or delete it temporary.
