# Thread: Formula Use

1. ## Formula Use

Ok, we all know that there is huge potential with the use of formulas. However, a lot of the time I find that I am trying too hard to put in a formula when a simple number will work. So, to get my creativity going, what are some creative examples of using the formulas? The more creative/useful the better!!

Hi Jkrager. Would you like to give some examples of what part of formulas you are looking for information on?

I generally use formulas mainly for family creation when doing arrays or restricting errors from occurring with regards to sizes of elements. I also do the occassional formula when scheduling data.

Simply evaluate the advantage that adding a formula will bring and then weight it up to see if its worth the extra effort?

HTH.

That is like asking a mad scientist to reveal their secret...formula

in RSA we have a simple formula for calculating the amount of bricks in a wall.
For a 220mm thick masonry brick wall
(Area / 1 m²) * 110
For a 110mm thick masonry brick wall
(Area / 1 m²) * 50
These are specific to our brick sizes here, but I am sure that you can replace with your constants.
I was fortunate to attend a training course with Phil Read, and he did some scary stuff with formulae.See attached images. Both same family just changed figures.
ps. Phil not to worry, I won't reveal the secret

Ok, if you don't want to share your deep secrets, then your screen shots will do. That is some cool stuff Mike!!
My idea for this thread is simiar to this: If I were designing a website, I could just surf the web to see what kinds of things other people are doing. If I were designing a house, I could drive around the neighborhood to see what other people are doing. If I wanted to create a kick-butt formula in Revit, I could come here and see what other people are doing. Get the idea. If you value your work as trade secrets, that is fine. The images alone can stimluate the imagination...
It may be that nobody is using formulas creatively. That could only mean one thing, TIME FOR TUTORIALS!!

Mike;

That's not nice.
Teasing people with something like that and not revealing the secret.
Isn't that what AUGI is all about? Sharing ideas, information, content, tips and tricks, etc.

PS: Autodesk should have online tutorials on how to create stuff like this.

I will impart with formulas and how to create them on the ATP If any one is interested???

7. ## Re: Formula Use

I'm sure when Phil reads this thread he will most probably post an example of what went into that construction. I really enjoy formula's and I try to use them as often as sanely possible. The power of Revit formula's still grasp my imagination everytime I get to create a new family.

Here is a Louvre Window that I took from someone here and cleaned up for myself. It is extremely well done I was impressed when I saw what went into this family. I've used alot of the same formula's elsewhere in other families.

8. ## Re: Formula Use

Thanks Mike that is very generous of you to volunteer your time.
Looking forward to attending the course.
Please keep us informed as to when it will be available.

9. ## Re: Formula Use

I used formulas/formulae to construct this cornice for gables. Is this the kind of thing you are looking for? If so, I will look for others I've done, and post those.

Captain

p.s. should I post these to revitcity also?

This mass that Mike shows of Phil's has been create by creating an mass family of an ellipse that is then rotated and reduce in size as its elevation increases. Now if you can put your mathematical skills together you should be able to work out a formula....?
