How do you create contours in Sketchup?

What are the 5 Rules of contour lines?

Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker in color.

What are the 3 types of contour lines?

Contour lines are of three different kinds. They are the Index lines, Intermediate lines and the Supplementary lines.

Which method should be used to determine the highly accurate contours in small area?

Direct Method:



These points are then surveyed and plotted on plan and the contours drawn through them. This method is the most accurate but very slow and tedious as a lot of time is wasted in searching points of the same elevation for a contour. This is suitable for small areas and where great accuracy is required.

What is a topographic model?

Topographic models consist of a scaled down version of an area of land and contours that show change in elevation. … Topographic models are most easily created directly from topographic maps that show the contours of the land, although this is not absolutely necessary.

Can you import Google maps into SketchUp?

Since SketchUp was owned by Google and initially used to crowdsource their Google Earth modeling, there are powerful, easy to use tools built into SketchUp to help both import maps into your models and also to geolocate models in Google Earth. … Type in the location you’d like to import maps from into your model.

What are the parts of a topographic map?

Topographic maps are a detailed record of a land area, giving geographic positions and elevations for both natural and man-made features. They show the shape of the land the mountains, valleys, and plains by means of brown contour lines (lines of equal elevation above sea level).
