Pipe cast iron elbow won't allow slope adjustments but PVC elbow will.

[davetexter]

I have been scouring the internet boards trying to find a solution.  I have downloaded a manufacturers cast iron elbow and it will not "easily" allow sloping adjustments.  I can slope piping using the PVC fitting (see attached) and easily use the grips in plan view to rotate the pipe and fitting but I cannot get the same results with the cast iron fitting. 

I can usually finagle a solution from time to time but it should be a lot easier to draft with fittings.  Having to re-engineer the coding for these fittings is extremely time-intensive so I can see how people are easily frustrated when they drop thousands of dollars a year for a program the under-delivers on their expectations. 

Any help with this is greatly appreciated.

Who told you that the content provided by Autodesk and manufacturers is going to be exactly what you need? The content provided by Autodesk only serves as an example and manufacturers make their own content according to what they need and what they think is needed for the people that might use it. Absolutely no guarantees that it will be everything you need.

Your next step is to decide if you can live with the inadequacies of free content, make your own, or pay someone to do it for you.

Good luck.

I'm trying the uploaded family and it is working fine with the slope on the Horizontal run. Mainly as indicated in your image the problem is because of two reasons:

1-The fitting is big and needs more space to fit, so physically try to elongate the pipe down so you can provide more space.

2- The fitting is built to work just on 90 degrees so the angle between the two pipes indicated in the image is not equal to 90.that is why it is showing an error.If it is one-time action I recommend just adjust the angle between the two pipes to be equal to 90(not more and not less) and trim the two pipes. This will work.

If you are using this family a lot I recommend replace with another one or adjust the family so you will have flexibility while working because if you want to follow my instructions on multiple cases it will be a nightmare.

If this helps you solve your issue kindly mark it as a solution to help others.

Echoing what @Mahmoud.Ziedan said, for drainage the bend family either needs to flex for different angles or has to be set at an angle which is appropriate to the pipe angles (usually 87.5 or 92.5 degrees depending on how the manufacturer defines angle).

OR you can alter the connectors to allow slope adjustments as below but in this case the bend angle will stay at 90 degrees but the pipe attached to the bend will skew slightly - looks weird but works (and in fact certain types of real fittings do accommodate slight angular misalignments).

To activate the “allow slope adjustments” you need to open the family, select the connectors, change their classification to global, tick the “allow slope adjustments” box, change the connector classification back to Fitting, reload into project.

Hope this helps.

Hello,

You can create a tolerance range and create the angle value that will be used in the lookup tables using this range:

- Geometry Angle, real angle.

- Tolerance

- Reference Angle = if(and(Geometry Angle > 90° - Tolerance, Geometry Angle < 90°+ Tolerance), 90°, 0)

Then use Reference Angle in the lookup formulas.

In the connectors, link the Geometry Angle.
