Length of steam coil

[genet]

I need some help here


I have been a member here for some time but never posted, but I do find alot of good info


Here is my problem


System WF3


I am making a number of steam coils and need to calculate the length of all of them


I used Helical sweep to create them but cannot use the mass length to get straight length because there is no skectch line


Help

if the cross section of the coil is constant,one way is to calculate the volume inside the coils,(copy the inside surface,cap the ends using fill, merge and solidify,then calculate the volume) dividing it by the area of the cross section(inside the pipe,not wall portion). that would be the length of the center curve.
other ways involves sweeping two lines in the form of an "L", then calculating the intersection.
(try to see if you can sketch an "L" at the center of the circle you already have. )

Could be misunderstanding this, but a helical sweep has got a path, why can this not be measured?

 

[genet]

Thanks for the quick reply from both of you


Wow Solid worm thats alot of work for the amount of coils I have to create


Kenppy, I thought they should have a path also but I cant get the path to show


Do I have to turn some setting on?


I have been off of Pro for a couple of years so I maybe missing something


Thanks again guys

post an example of a typical coil.

 

[solidworm]

use the surface area, that way you don't need to calculate the volume.
(outer area of the coil surface)/(perimeter of the outer wall=2*pi*r)= length of center curve

Sorry for being ignorant but how do I do that

 

[genet]

That last post was for kenppy

 

[solidworm]

surface area? its under analysis>measure>area, thought it was for me.

No problem


Kenppy, How do I post a typical coil so you guys can see one of them


I could post the part if that is possible

 

[solidworm]

there's a diskette icon on top of theeditor,when you post here, that is the attachment icon. zip the file first,then attach.

Thanks again guys


I know there has to be a simple way to do this

 

[solidworm]

saw your part, i already mentioned the easiest way

its solid, so u dont need to merge or solidify anything. just get the volume from,analysis>model>math props, then devide by the cross section area of the solid pipe = pipe flat lenght

Here was a method someone posted on the PTC site. In this model you need to fix the bottom end to get the overall length.

Thanks to all for the help


That last one was an interesting way to do it


Thanks again everyone
