Expression of grades on Profile View bands...or anywhere for that matter...

Hi All,

Typically here in NZ, and for as long as I have been in this business, we have expressed slopes in the form ...2 : 1  but the same grade would be expressed as   1 in 2.

I wonder how much support there would be from well qualified Civil Engineering folk to get AutoDESK to allow this form of display for grades?

cheers,

1. You look at the same grade and you can describe it as run:rise or rise:run format:

2. You can choose that the first one will be “rise” and this grade format is called rise:run.

3. You can also choose that the first one will be “run” and this grade format is called run:rise.

 This one is preferred by You:

Thank you...but...

My point was that we would like to express our grades as ...  1 IN 200    not   1 : 200.

C3D does not give us that opportunity.

cheers,

Peter

Rise over run - run over rise has always been the unitized value and that is what c3d does. 1 in 200 would physically mean 100 in 20,000 which is about 0.005%? Are you sure about that? Seems might flat.

If you want to build the expression format like e.g. 1 IN 2 do the following steps:

1. Build your own expression and call it e.g myRun

1/ABS({Grade between Point 1 and Point 2})

2. Build your own grade label and use the myRun expression

- add the constant description 1 IN and add the myRun expression

- change the myRun Precision into 1

1IN<[myRun(P0|RN|AP|GC|UN|Sn|OF)]>

3. You will get your preferred description format

If you want to show the minus sign in this format e.g.   -1IN2 :

4. Add a new expression and call it e.g. mySign

{Grade between Point 1 and Point 2}/ABS({Grade between Point 1 and Point 2})

5. Use this expression mySign in your label

<[mySign(P0|RN|AP|GC|UN|Sn|OF)]>IN<[myRun(P0|RN|AP|GC|UN|Sn|OF)]>

6. Now you can also show the sign of your grade

I hope it will help
