VERTICAL AND HORIZONTAL ANGLES

[Anonymous]

PRESSURE PIPES:

MY DOUBT IS WITH REGARD TO VERTICAL AND HORIZONTAL RESULTS. THE VALUES ARE NOT CORRECT.

BY MEASURING PLANT AND PROFILE, THERE IS A DIFFERENCE BETWEEN INFORMED VALUES.

How are you measuring the angles? Are you using the "compass" when laying out - pipe can deflect 5%%d per stick, is this it? Does your profile view have a vertical exaggeration? Are they bends that you are measuring angles, and, if so, are the bends rotated, or turned to introduce a vertical bend along with a horizontal bend (turning a bend will make horizontal angle be less)?

Maybe post a dwg?

Be advised that not all pressure network parts appear in the profile view correctly. See https://forums.autodesk.com/t5/autocad-civil-3d-forum/pressure-part-won-t-display-in-profile-view/m-...

In reality the Civil 3D pressure network routines fall short. It is what it is. Be glad that it is a pressure system and not a gravity system or the STUFF would be flowing backwards.

I agree, you need to provide a little bit more information. What angles are you referring to? If you want good answers, you must provide enough information for us to help you out.

Also, I've posted in the Civil 3D Idea Station about a possible way to revamp pressure networks, go check it out and if you agree, vote it up so Autodesk know there are a lot of people that need this functionality. You can see the idea HERE.

IN PROFILE, THERE IS NO EXAGERATION. 1000H AND 1 VERTICAL.MEASUREMENT IS BEING MADE IN PLANT AND PROFILE AS DESCRIBED BELOW:

Can you post up the drawing for us to look at?

That label has nothing to do with the pipes. The label is showing you the horizontal, vertical, and absolute angle of the fitting itself. Since it's a 45 degree fitting, the label will always show 45 degrees. The fitting is rotated slightly around one of its ends so the horizontal angle is less than 45 degrees and the vertical angle is greater than 45 degrees. If you calculate the resultant angle in the plane that slices the fitting through its middle, it will be 45 degrees.

To help you see that this is the case, if you erase both pipes that are connected to the fitting, you'll see that the fitting label doesn't change. If you grip edit either of the pipes so it changes the resultant angle, again, the fitting label doesn't change (except possibly for station label).

Hope this helps.

Thank you very much for the solution. through its explanation I can demonstrate to those involved in the project the values ​​presented. Thank you very much.

See you can help me not the same file ... In the profile, of the larger length pipe, the shaping presented in the profile does not correspond to the planting in plant. How could you solve that?

[Anonymous]

What station is the "larger length" that does not look right in profile at?

[Anonymous]

open the previously attached file. Note in the profile that the stacking is not correct. the connections do not appear on the correct stake.

[Anonymous]

I opened the file. I'm having trouble finding exactly what you are describing.

What station is the problem at?

[Anonymous]

the values.

Look at the bottom ...

E17 + 12.82m?

The values ​​do not match the correct values.

if distances are measured for all vertical points noticed, they will not be equivalent to your plan. Always observe the correlation between plan and profile ...

How can I  plot Horizontal Angle and Vertical angle in Autocad Civil 3D land desktop taken from two different Station ?

The Horizontal angle and vertical angle were taken in the field though the method of intersection . Sample Excel Screenshot is shown Below .

[Anonymous]

Horizontal location of the obstruction is where the horizontal angles intersect. Draw lines from instrument station to backsight station and rotate by horizontal angle. Where they intersect is the horizontal location.

Elevation of the obstruction can be determined using trigonometric functions and the horizontal distance you determined in the first step. I think it is: El. Sta. + HI + (Horz. Dist./TAN vert. Angle) or something like that. Use the average of elevations computed from each station.

Redundancy - an observation from a third station - would be good since you have no way to check the results.
