How to measure valley angle?

[Slawek_Bielawa]

Hi folks, probably a very basic command here, but how do I measure a valley angle on a chute?  See photo attachment.

hI @Slawek_Bielawa,

I am sure there must be a better method but I simply go to paperspace and throw  a DIMANG on the "flat" view.

Hi, thanks but this is not a valley angle...  

Attached below shows what a valley angle is.  I need angle C

Give the UCS command and then the ZA option (Z axis).  Click two point along one of the edges so that the z axis is collinear to it.

Now give the plan command and you will be viewing the object down the z axis. You can add an angular dimension between any two lines each of which lies on one of the two planes to give you the valley angle. The angle will be determined for the current xy plane which is perpendicular to the two surfaces. 

Note, I found a reference that defined the valley angle as the angle between the two surfaces.  This is different than the illustration you provided.

I don't think we're talking about the same thing here...  take a look at the attachment, I need the slope of the angle in red.

Here is a calculator to determine a valley angle.  Do you want to run a calc to see if it matches what you got?  I'm not sure what angles you used in your example to come up with 113.37

GCS is active

Send UCS

Clic 1 and, before you clic 2, enter and validate .z then @ and validate and then

Clic 2

@0,0,1

Done with the UCS you need to measure or dim.

edit :  X warrantied to be paralell to GCS, you can use ortho for the third anonymous point of a angular dim wich base point is 1 (your new 0,0), second point is 2.

It's simpler than any of that....

DIST command, pick points at the bottom and top of the valley.  One of the things reported is the:

Angle from  XY Plane = [whatever it is, subject to your angular Units mode and precision settings]

like so maybe?

Very true. Typically so easy that we forget it !

Ah, there it is... thank you!  I knew there was an easy way!
