Welcome to SketchUp, Vray and other Resources

Everyone is capable of learning. Learning is part of life. It is a social process of living and bringing everyone to share their inherited resources and discoveries. All of us can influence the life of others through sharing and caring. It is our belief that everyone should be a lifelong learner.

I am putting very important visualization resources and series: tutorials, tips, tricks, VRAY materials and settings, and mini-the-making (MTM) processes.

Tutorial: How to model Terrain from Autocad to Sketchup

This is the second tutorial of Edgar Navas in this site. This time, Edgar share his knowledge on on how to model a Terrain in SketchUp from an imported model in Autocad.

First of all in Autocad, I remove anything that does not serve me in SketchUp

Step 1: Layer Walk

Use the Layer walk in AutoCAD to isolate the contours. See the image toolbar below.

With Layer walk, I manage to identify the layers (road and contours) that I wanted to isolate.

Step 2: Turning off the unwanted layers

All the other unwanted layers that does not serve me were all turned off.

Step 3: Copying and pasting to a new Autocad drawing file
After isolating the layers that I need, I copied them all and pasted them to a new Autocad drawing file and saved.

Step 4: Importing the Contours into SketchUp.
In SketchUp, I imported and loaded the dwg. file. Be sure the Autocad Drawing and SketchUp scale are the same.

Select all the contour lines.

Step 5: Using "From Contours"
Once all the contours were selected, open the sandbox toolbar. Click the icon "from contour" (see below image).

Below shows the progress of terrain surface generation. The time to complete the process depends on the complexity of the contours.


Presto! The terrain surface has been completed.

Step 6: Removing Unwanted Geometries

Deactivate the layer of the imported contours in Autocad. Also begin removing some unwanted geometries. To view these geometries, click view..hidden geometry and delete the unwanted lines and faces. (see the unwanted geometries below)

This image shows the deletion of unwanted geometries.

Step 7: Applying Texture Colors
Finally, we will apply texture Color.

And if I want the contour to display, all I have to do is to activate the layer where they are.

  2. Hi, Thanks for sharing this information. I am new to Sketchup and not able to do step 7. How to apply texture color on contour plan? Could you please share the method on this.

    Thanks.
