Terrain shaping in Quadrimodel

Terrain shaping

Find it here:

MOUS_ICO Modelling >Terrain shaping

You can define new heights and creat new TIN (Triangular Irregular Network) with this tool.

Under input: Choose Objects you want to use existing heights from. Point elevation calculated from chosen input will show with a underline

There are three possibilities under settings that are on the toolbar:

Equidistance

Slope

Widgets

Equidistance: Select in what kind of equidistance you want the contourlines to show. Contourlines will show and change dynamically in the model when you create the terrain. Default is 10 cm.

Select wheter you want to create slope With percent or ratio. Default is percent. By clicking on the ikon you chose between percent or ratio.

Widget on / off: Widget displays available short commands and their function. By default, the widget is on. Press to turn on / off.

To begin designing the terrain you must have a plan window open.

Tip: Create a separate plan window where you do not have many surfaces so you easily can see the terrain. By having a 3D window open in addition, you will be able to see the terrain in 3D when you are creating the terrain.

Methodology:

  1. Set the first point either by specifying x, y position in the plan window and entering the height, or be in x, y position in plan and press O to use existing calculated height.
  2. Widgets changes according to where you are in the process. You continue to insert new elevetion heights and use various short commands to set guidelines for elevation heights.

These are the different commands you can use:

O: use height(Z) from Object/ surface (the height from input is used)

V: select nearest point elevation as Reference (by holding the mouse near a point it will snap to that elevation point)

P: Select next point elevation to insert slope arrow ( insert a New slope arrrow from an elevation point by holding Your mouse close to the elevation point you want to put a new slope arrow towards)

L: enter new slope (gives the possibility to change the slope value)

H: enter a height

R: fixed reference / running reference (calculates elevation points from one point/ calculates elevation points consecutively)

F: descend / ascend ( the next point will be below the last point/ next point will be abow the last point)

When you press enter you quit create - mode, and you come to a pause mode in which you can click on another location to add a new elevation point, or use V to select one reference point or O to an existing height. You can also click on point or slope to edit this.

You do editing by:

To edit height og slope:

Click point height or slope and change the height (Z), or roll the mouse wheel, O provides existing height. With M selects all and you can roll the mouse wheel to change all heights. To change the slope must also specify (with V ) which point height you chose to be a reference.

To move a point elevation: Click the plus sign and drag it to the new position (X,Y).

Esc erases everything you have done up to the last pause mode, witch is the last time you pressed enter. If you want to delete points you created before the pause mode select the elevation points and press delete.

Select OK to exit, if you select cancel a dialog comes up asking if you want to exit the tool. By leaving the tool you will lose the work you have done until the last time you pressed enter.
