To create a terrain curve, use Terrain Curve command.
You have following possibility to launch Terrain Curve command:
- From Modeling drop down menu select Terrain Curve
Terrain curve is intended for the terrain modeling commands which require a curve (e.g. Flatten terrain inside of curve, Push/Pull terrain inside or along of the curve….). The terrain modeling commands allow drawing of terrain curves during the commands itself or using any existing preselected terrain or material curve. The drawing of a terrain curve in advance has good sense for the Curve Push/Pull command in case a different height is required in each point of curve. In this case draw the terrain curve in advance, set the additional heights into the grip points, preselect the curve and then run the Curve Push/Pull command.
When Create Lake command is launched move cursor in terrain and pick some points to create a curve.
Hint:
It is recommended to use top view while creating the curve to easily gain the desired shape of the curve and point positions.
Hint:
Use right mouse click context menu to edit the curve during creation.
Hint:
To set a height of a curve point above terrain use Edit additional heights command from right mouse click context menu.
Note:
Make sure that items Terrain Curves and Curves in side view in Visibility Filter are on to see curve in side or top view.
To finish creating the curve choose Finish from right mouse click context menu or press Enter.
To edit created terrain curve hover cursor over it so, that it gets highlighted and from the right mouse click context menu choose Edit Terrain curve.
Note:
Make sure that item Terrain Curves in Selection Filter is on to allow selecting any terrain curve.
To delete the terrain curve. Activate the Top View window and hover cursor over the terrain curve so, that it gets highlighted. From the right mouse click context menu choose Delete Object(s) and click the OK button or press the Delete key.
Hint:
Hold down Ctrl or Shift keys or use selection window to select multiple curves.
Since terrain curves allow also generating of grass, they can be used for populating of grass over variously textured area without necessity to consider priorities of material curves and transitions between them.
