This option is used to view and also create ‘1v in’ Slope Range Files in the project.
The video below will show how to use a Range File.
Continue down the page to see the ‘1v in’ Slope Range File Panel options.
To view the ‘1v in’ Slope Range File Panel, Use: File => Range Files => Slope (1v in)
Creating a Slope Range File
To create a Range file in 12d Model is quite simple, there are only 4 columns:
- <From> column – enter the lower ‘1v in’ horizontal value for the slope range for that row.
- <To> column – enter the higher ‘1v in’ horizontal value for the slope range for that row.
- <Colour> column – enter the specified colour for the slope range for that row.
- <Comment> column allows a text comment to be entered and recorded for that row. The Comment column is optional, the cell can be left blank.
The <Finish> button will close the panel but will not save the file – be careful! Keep reading.
Below a simple ‘1v in’ slope range file is being created, with 2m horizontal values for each slope bands per row in the file.
To pick a colour for each ‘1v in’ slope band, right click on the colour cell and select the colour required. If you have a lot of colours/rows to select, there are tools and options available to populate and fill out the Range File panel,
Visit this post: Populating Range File Panels
Once the file has been filled out it needs to be saved, so that it can be used in this project and possibly other projects. There is no need to create a new file for each project.
Firstly type in a File name for the new Slope Range File.
Then hit the <Write> button to save the Slope Range file, at the moment it will be saved to the current project’s working folder.
How to Open and Read a Slope Range File
If there is a Slope Range File available, either from the Library, User_Library or another project, then it can be used and read into your current project.
Pick the <Range File> button and then walk right on the [Lib] (Library) directory, and select the ‘Slope.srf’ file.
Note: The [Lib] (Library) directory always contains the files that are provided with the 12d Model program. These files can be exactly what you are looking for and be used straight away, or a great example file that can be used to create the file required.
The Slope Range File panel will open the selected file as shown below.
In this example there are 100 different colour graduations to differentiate between 0 ‘1v in’ and 100 ‘1v in’.
