Calculating side slope

Good Day! 

 

I have created an existing ground profile of a surface I will be working on which runs through the mountains,  Is there a way I can plot points along my existing ones say two meters above and two meters below the center line then create a profile or calculate slope between the two points?

Probably, but you can plot a profile view for your alignment:

 

1. create a FL or 3dpoly from you points, copy, raise lower and project to the view.

2. create a point file of station offset and edit in excel to create a profile input file

 

 

 

Thank you

How do I "raise, lower and project to the view", sorry I'm fairly new to civil 3d still.. Also Do I have to input the offset for each point in the file? Or is there a way I can automatically offset it?

Ok If I understand correctly, you have a line if points along your alignment of existing and you are wanting to see a cut and fill windowe Hopefully the points are sequential.

 

Create a FL with the transparent command for point numbers (if they are not too numerous you can simply draw the FL) . You should get a FL from one end of the alignment to the other. Now you can make two copies for above and below. you do this with the copy to site command on the FL. one copy to -xmeter and one to +xmeters. you'll have 3 FL now.

 

1. Create a profile view for the alignment, adjust the elevation tab to be in the range of known point elevations. You will now have a blank profile     view.

 2. Qselect all the FL's (properties dialog filter all FL)

3. home tab>> profile views>> project to view ( accept objects elevation)

4. draw your layout profile betwee the cut and fil line

Thank you that is what I was looking for 🙂

 

One more question.. sorry, I am trying to create an offset alignment now, I want it offset 7m each side of centerline.  The offset will take effect on the left side but nothing happens on the right side?  Is there some setting I am possibly missing?

What do you mean nothing happens on the right side? no offset was created? make sure the number of offsets is not set to "0"
Thank you

It does nothing on either side if it is set to 1, If I set them both to "2" there are two offsets created on the left but nothing on the right still... It's kinda weird

You got this? Or are you looking for a profile?

Hello,

"No. of offsets on Right" options is zero. You should set it  1. It means you can create only one offset for this side.

Yup! This is the one! I don't know what it's issue is..

Your alignment may have geometry that precludes the offset. i.e. too tight a radius or kink?

was your alignment created from objects or drawn with the layout tool bar?
I suspect objects.

I loaded my survey points, Created a surface, Created a feature line with elevations, Loaded quick profile then exported to Land xml file, Inserted the land XML file which dropped the alignment along the line, then set my start point from the alignment. All I had to work with was a .shp file from a survey company. This is for a pipeline bid project so information is very limited

I used the "3dpoly, 'pn, 1-4333" command as there are 4333 points in my survey file

I guess what I need is the `Z`` Coordinate 7 meters to the left and 7 meters to the right of these survey points.  My employer would me like to manually calculate the slope.  Of the side hill sections.

Well, you have confused the heck out of me. You have no surface only points along alignment, you have a surface? Which is it?

Ah Sorry! I have a surface points along my surface and an alignment.

That does not clarify anything. I appologize but is english not you first language? I have lost track of what you are trying to do?

I appologize,

I will outline the steps I have taken please correct me if I am wrong ( I am new to Civil 3D and have been tossed into this):

1. Import the survey points from .xyz file

2. Create surface from the points file

3. Create feature line along points and a quick profile from this line

4. Export the land xml file containing the quick profile then Import the land xml file back into my drawing which automatically creates the alignment along my survey points.

 

What I am looking to do is find the side slope along these survey points to calculate the volume of material we will be required to remove in order to build the Right of way for this project,  The project spans over multiple mountains with severe vertical and side slopes which we are required to cross.

 

I really appologize I am not meaning to frustrate or confuse anyone. Question.png
