Guide support modeling

Question

Hi, 
 Please help me. I would like to model guide support for cryogenic pipeline like on the sketch below. 
 The guide support is 300 mm lenght. Shall I model as two guide supports with spacing 300 mm between each other? 
 I assume that Autopipe treat guid support as a point without lenght.

That's how I would go about it. I may even stick a support mid span between the outer supports as well to ensure any deflections of the piping does not exceed the boundary condition of the actual support.

I am for this solution. Please bear in mind that to make things easier you should build a model of secondary suport, e.g. vertical steel element, then both guides attach to the same endpoint of the steel element. No only stiffness of this element would be taken into account, but also you will have all the loading grouped together, including torque, that usually would be omited if you insert only one guide. Like advised during our workshops... :-) 
 
 BTW: Luke, it would be great to have capability to report grouped loading of secondary suport this way. It still isn't so simple and requires some hand calculation...

Hello Pawel, 
 
Yes, you can add impose support displacement to this support. Add it to the Anchor at 5103 in Maciej image above.
