Showing props in fans

[the_cad_monkey]

I just wanted some quick opinions. I am making some families of wall propellers for a company. Do you guys feel it is neccessary to add a propeller in the fan? Should I leave them out to save on file size? With the propellers in, they take 4 times longer to open then most files.

Would you please edit your post to use full words? Does props mean properties, propellers, support, or something else?

And what are "wall props" as in "making some families of wall props for a company"?

How many propellers you have on each fan? If you have 4 on each fan and the file takes 4 times longer to open, than I assume each propeller is as complex as the fan itself. And if that's the case, couldn't you create the propellers simpler?

"Four times longer to open" should give you the answer. My opinion is that the detail of adding propellers in a wall mounted exhaust fan is overkill and possibly going to kill your performance in any sizable Revit MEP projects.

While detail sure makes some views look nice, isn't the idea to accurately represent the basic physical size and shape of the product. Beyond that the engineering data that you include is the other real benefit and hopefully the time saver for the end user.

Thats interesting.

I've modelled my propellar in Autocad and imported it into Revit. The 3D representation is straight out of the catalogue, all the small flanges, bolts and tiny curves are ignored but our fans look like a spitfire fan and spot on.

This helps us to recognise the fan-X type in elevations, sections, and perspective without the need of a reference.

but if you fan is taking '4 times as long' than you must be doing something wrong.

Well said. I don't see a need to go into such detail, especially if it is hurting the performance of the model. Do you think the contractor that is installing the fan is going to care if you have a propeller shown on your drawing? Probably not. Yes, it looks cool, but it is not necessary.

Thanks for the input guys. Now maybe I can convince my employeer to let me take them out. I did not want to add them, but they insisted. Not only are they a memory hog, they are not fun to model in Revit. Thanks again.

Ah, so you have people with no Revit experience calling the shots.... I feel your pain.
