Hi All,

 

Sorry if this is an elementary question but I can't for the life of me figure this out!

In the attached image I have displayed my formulas which are driving the geometry of an arc.

When the Rise is greater than (Span/2), the geometry breaks.

What I am trying to do is implement the following formula for the value of my parameter 'Rise':

Rise = if (Rise > Y, Y, Rise)

This gives me the error message: "There is a chain of circular references amongst the formulas"

 

To by pass this I made another paramter called 'Rise Condition', which you can see in the attached image.

The formula:

Rise Condition = if (Rise > Y, Y, Rise)

Works however I can't figure out how to associate this with the value of my parameter 'Rise'.

 

What am I doing wrong? Please help !!!

 

Regards,

D

I dont understand what Rise=Rise is suppose to mean (if Rise<Y) - Looks circular logic. 

 

I understand that Rise Condition = Rise,  if Rise has a defined value.  Thats not circular logic.

The formula seem correct.

But the actual rise of your arc has to be controlled by Rise Condition (add a dimension between the two horizontal ref. planes?). The Rise parameter is just a manual input, it can't control the geometry directly, otherwise it create a circular chain, no?
