Piping

[rajamanickam_ps]

Dear all,


Have a look on the following two figures.


I have to pointsin same plane.


When I am making pipe,it should not intersect at any place as shown in figure. 1.


If you look at the figure. 2, I have created this using multiple points. And thus I arrived helical coil like structure.


As such I increase/decrease the length of this segment I should get the change only in the helical coil diameter.


Thanks,

Hi Raj,


I tried ur routing path and nearly came up with a solution. i dont have pictures of that but i will try to explain u here.


1. I assumed that there can be offset in axis of the segment before and after the coil.


split the entire route into three routes(pipe follows)


1. start port, segment before coil


2. coil segment


3. segment after coil.


to make things easier, make pipe 1 and 3 similar(equal length)


and for pipe 2, u can use the following equation for a datum curve and give pipe the follow curve option


x = r Cos(t * @)


y = r sin(t*@)


z = 2 * t


@ - theta


t - cartesian variable available in Proe


for z, i have given 2(u can normally give a min of 2 * pipe od distance)


u will get a simple helical curve.


2. Now the actual control is the value r.


if the fixed length of pipe is say 10, we know the lengths of pipe 1 and 2(as we have kept constant)


then r will be = (fixed length - (2 * pipe 1 length)) / (2 * Pi) (perimeter of a circle formula)





this is only an idea, if i can achieve it, i will certainly send u a sample model.


hope this works
