“flip control” in family affect the centre of the member????

[JH75]

I had a rafter and was wondering why it was going all over the place when I changed it the Lateral Justification to Side 2.
After scratching my head it figured it out – it was the “flip control” symbol that was not close to the solid of the rafter.

How come that affect the how the centre of the member is calculated???

I wouldnt even bother with the flip option in the member....you can achieve all of that by rotating anyways...if its adding problems to your family just take it out altogether

These are issues for any non-symmetrical member.

While rotating works to a point, purlins can't be rotated u need them flipped.
There are a number of ways to get around this, mirror visibility, seperate families, labelled nested families.

Take your pick, but again this issue should not really exist as the side 1 and 2 of the beams tool should work alot more like the walls justification tool and should be on the options bar or ribbon.

I have rotated purlins in the past, its definately achieveable..
I think the key was making them without shared paramaters or some such..the method escapes me now but I have definately done it for a curved roof - there is a post of how I achieved it somewhere...

Just something to add into this discussion.

If you use a sweep by profile for you structural members, you can apply a parameter for the angle of the sweep

This will work separately from the cross-section rotation so you can still control that separately if required.

If you simply want to have a parameter for flipping a member, you could create a yes/no checkbox for member flip and then drive the profile angle parameter with the yes/no

See attached for an example on one of the OOTB families

Oh you can rotate them but it won't flip the orientation. You can draw them in reverse to get your profile flipped :)

However beam systems make alot harder to change without unpining them.

Oh right, I misunderstood I thought you meant cross sectional rotation...
Yes you are correct!
