Drawing terrain in SketchUp does not require you to be a pro in the 3D designing. You can sketch the model as simply as you draw a line on a paper. But your 3D model needs other things to mirror the objects or scenes as accurately as the real one. The model you are drawing gets a special look when you add grounds and landscape. Along with terrains other forms of designing create a visually satisfied project. But how SketchUp perform all these tasks so efficiently is the question of many modelers. The content brings out the hidden facts of SketchUp tool in designing terrain and other round faces.
The answer actually lies in SketchUp Geometry. All SketchUp users must be familiar with the term – Sandbox tool – the tool needed for designing terrain. With this tool, you are originally using a special type of geometry – TIN that allows you to draw anything as per your wish.
TIN stands for Triangulated Irregular Network which is commonly popular as ‘a group comprised of triangles.’ The below image shows hills carved by TIN.
The content below deals with technicalities of designing TINs and Sandbox tools. The basics of designing that you must learn to Sketch the complex model in 3D.
Get started with TIN: If you are creating TIN first time, then you must try simple designs rather than opt for the complex ones. You need to import contour lines from another application or can import terrain from Google Earth using SketchUp building tools. Your drawing onto the TIN can is used in your design. But the easiest option will definitely be drawing a flat rectangular TIN.
Use Sandbox tool: Sandbox tools stay in a sandbox toolbar or you can follow the steps – Tools > Sandbox
If you are designing a terrain, you can geolocate the model or add a geographic location embedment that places your model into a specific point of the model. Advantages of using geolocated the model are given below:
• You can get a comprehensive idea of sunlight and sun shadows that add a different angle to your model. Light effects always take a picture to a new level and your design will get a sense of reality with this.
• You can view your design in Google Earth.
Geolocated terrain helps your model locate into a specific place on the earth. You can also add different functions and features with the sandbox.
