Dave G Posted August 12, 2005 Share Posted August 12, 2005 Is there a way of obtaining the weight of a part in Kilogrammes per metre ? Quote Link to comment Share on other sites More sharing options...
Guest IronKevin Posted August 12, 2005 Share Posted August 12, 2005 First, go to Format, Units and set Meters and Kilograms. The run the Analysis command. IK Quote Link to comment Share on other sites More sharing options...
Dave G Posted August 12, 2005 Author Share Posted August 12, 2005 Sorry ~ Still confused and losing the plot. Say, a channel weighs 10.2 kg/per mtr - in a scene I produce this channel and make it 1mtr long, the weight of this part should then read 10.2 kg from the Analysis tool bar I've input the mass density of the material as 10.2 from the part properties although do not end up back with 10.2 on the Analysis ??? Thanks Dave Quote Link to comment Share on other sites More sharing options...
mmccall Posted August 12, 2005 Share Posted August 12, 2005 Is the volume of your component truly 1 cubic meter? I just did it with a simple block.. but can you attatch the model of the channel you are using?... The units for the density would be "weight/meter^3"... If the volume of your geometry is 1 cubic meter... or 1 meter long by any other dimensions that will give the volume to be 1 cubic meter.. then you will end up with a weight of 10.2 kg.. Seems like it should all work itself out.. there would have to be something wrong with the geometry.. or the tabulated value for the weight of the channel or given dimensions are incorrect.. maybe the tabulated weight is only a close guess... How far off are your results? If you are converting to metric in the scene... you may already be behind the curve... I ran into some issues on a previous design from switching units back and forth... rounding error stacking... Attatch the file if you can...

Mike Twining Posted August 12, 2005 Share Posted August 12, 2005 (edited) Is there a way of obtaining the weight of a part in Kilogrammes per metre ? 10794[/snapback] Nope. IronCAD tool will report total weight only (kg). You would have to manually divide the reported weight by the part length to obtain what you are looking for (if you do really want a report of "weight-per-length"). The weight density input in ironcad is a weight-per-volume (not weight-per-length) input, which is why you are not getting the results you expect from your experiment.

Dave G Posted August 12, 2005 Author Share Posted August 12, 2005 Hi, I have attached a simple channel with a weight of 10.2 kg per mtr, the channel in the scene is 1mtr lg - the units in the scene are set at, as I work in, Millimeters and Kilograms. Never was any good at maths, wish I'd studied ! Thanks for your help Scene2.ics Quote Link to comment Share on other sites More sharing options...
Mike Twining Posted August 12, 2005 Share Posted August 12, 2005 ...back-to-back posts... anyway. Another way to put it: Density (in ironcad) is a material specific property, not a geometry specific property. Quote Link to comment Share on other sites More sharing options...
Alex Khenkin Posted August 12, 2005 Share Posted August 12, 2005 1) Input the proper density of the material in Part Properties. 2) Obtain the total mass in kg by doing Analysis 3) Measure the total length of the part in meters 4) Divide the total mass in kg by the total length in m -Alex.

mmccall Posted August 12, 2005 Share Posted August 12, 2005 (edited) AAAHHH... I see the original question... Mike Twining is correct... But as far as the model is concerned... again.. you would only expect the weight of a 1meter part to be 10.2 from the analysis.. only if you had 1cubic meter volume... The volume of the part is less than 1cubic meter.. therefore you are getting a weight less than 10.2kg. Alex has it... HA... I am not a professional... I have to deal with these physics professors everyday... like being in school.... better to ask than to get it wrong...

Marcus Bertilsson Posted August 14, 2005 Share Posted August 14, 2005 I see the point, having the possibility to put in weight/length. That would be nice to have for cables, wires, chanels, ducts, ladders etc where the manufacturer only state the weight/length (in most cases kg/m). It should be possible I think to do that for extruded or sweeped geometries. Put it as an ER! / Marcus Quote Link to comment Share on other sites More sharing options...
Guest bkline Posted August 14, 2005 Share Posted August 14, 2005 There also needs to be a way to display this data in the BOM. And have the BOM add up the entire weight of the product. Another ER to add to the very long list. Quote Link to comment Share on other sites More sharing options...
