Pipe elbow fitting to show straight not curve

[EddieFromDC]

Hello,

Still no response in another forum so I'm posting here. (My deadline is nearing).

For detail level "Medium" we would like to have straight lines for elbow pipe fittings

instead of curve.

I can't seem to lock one of the lines in the family when in a 45 degree elbow.

We would like the single line pipes look like image no 2. 

Can someboby please show me how to lock the lines properly....Thanks.

Attached is your modified family. I added two additional reference planes, one vertical and one horizontal. I then drew the model line from the center point to the intersection of these planes. Each of this planes is constrained by one of the new parameters "Offset X" and "Offset Y" respectively.

CADastrophe,

Ah, reference plane. Learn something important today...Thank You!

CADastrophe,

I followed your instructions but cant seem to make this fitting work. When you get a minute could you please

tell me what I am doing wrong or not doing....Thanks

Either: 1. Start over again or  2. Delete you model lines and new Ref. Planes, change the angle to something besides 90° and choose to remove constraints. Now...

1. Set the 'Angle' parameter to 60° or so to make it easier to work. If the angle is at 90°, then some Ref. Planes will overlap.
2. Create the two offset parameters and set their length to 1'-0" for now. Again, easier to work.
3. Create the two Ref. Planes way above and to the right of anything else, and set to "Not a Reference" under properties. I found that sometimes drawing them too close other elements creates unwanted, invisible constraints.
4. Create dimensions and constrain the Ref. Planes to the two parameters. Ensure the planes intersect.
5. Draw your Model Lines beginning at the intersection of your ref planes down to the center intersection, and to the left side. This will create the desired association.
6. Set the formula for the parameters, Horizontal: "cos(Angle) * Center Radius"  Vertical: "sin(Angle) * Center Radius"
7. Set the angle back to 90° to ensure proper functionality.

Okay...Thank you very much.

Does anyone know a quick way to modify the out-of the box REVIT copper elbow so that it displays with a straight 90 line in coarse view rather than curved line. I dont even mind if it shows tick marks at the connections. But the curved lines look horrible.

I tried just deleting the curved line and drwaing a straight line but the line does not adjust with the angle of the fitting.

Please help!

Thanks,
