This option is used to calculate the aspect (direction) that each triangle in a tin is facing,
and will create coloured faces in a model. This option can also create boundary strings
that bound the triangles in the same aspect range.

Continue down the page to see the Aspect Analysis 2 Panel options.

To view the Aspect Analysis 2 Panel, Use: Tins => Tin Analysis => Aspect => Aspect Analysis 2

Pick the <Tin> button and select the tin required.

Pick the <Range File> button and then walk right on the [Lib] (Library) directory, and select the ‘Range_Aspect_Colour_Simple.arf’ 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.

Either type in a new model name or pick the <Model> button and select a model from the drop down list for both the ‘Model for faces’ and ‘Model for boundaries’.

Hit the <Aspect> button to create the faces in a the model, and the boundaries in a separate model.

Turn on the faces model to see that the faces have been created – even check them out with the String Inquire option.

Turn off the faces model and then turn on the boundaries model to see that the boundaries around the aspect faces have been created – even check them out with the String Inquire option.

The z-value for the boundary strings are taken from the line of the range file, that the boundary has been created from. In this example it is a red_248 colour on line 4 in the range file, hence the 4.000 z-value.

Tick the <Boundaries as Faces> option and the boundary strings will be filled in (faces created) inside the boundary strings.

Hit the <Aspect> button to re-run the panel, and as shown below the boundary strings will be draped onto the tin. This option creates a lot of points, and if you only have a small points license it can be used very quickly.

Note: Every time the panel is re-run the data is recreated, to clean the models out, use the ‘Clean Model’ option found in: Models => Clean

Tick the <Boundaries Draped> option and the boundary strings will be draped onto the
‘survey tin’. Taking the z-vales from the tin as shown in the image below.

Hit the <Aspect> button to re-run the panel, and as shown below the boundary strings will have the z-values from the tin assigned to them.

Every time the panel is re-run the data is recreated, to clean the models out, use the ‘Clean Model’ option found in: Models => Clean

The ‘Boundary Colour’ option is not used for this panel, as the colour for the boundary strings are taken from the aspect range file.

If you would like to differentiate between the boundary strings more than how these boundary strings are created. There is an option that will add extra text to the string names.

This can be done by using the Aspect Analysis 2 New panel, if you would like to learn more about the Aspect Analysis 2 New Panel and how to utilise it,

To open the Aspect Range File to view its contents, pick the <Range File> button and then select the [Open] option from the list.

The Aspect Range File panel will open and have the file shown.

In this example there are only four different colours to differentiate between north, east, south, and west directions.
