From GardenCAD to SketchUp

SketchUp is a 3D modelling software application. You can use GardenCAD designs as a base to create SketchUp models by exporting a raster image (such as a Windows BMP file) from it and importing the image into SketchUp. There are considerable time savings as tools such as line and rectangle can be used to trace over the raster image. The SketchUp model will be dimensionally accurate. This module describes the process in some detail. We create a design for a rooftop garden.

Step 1

Apply at least one dimension to a convenient line in GardenCAD in model space as shown in the figure below. This value will be used in the SketchUp environment to scale the SketchUp model appropriately.

Step 1

Step 2

Set the background coplor of model space to white. Right click on the desktop and select options. Choose

Set the background color of model space to a dark grey.

step 2

Step 3

Use File>export Raster and save the file as a bit mapped file (BMP, JPEG etc.) to a known location.

Step 3

Step 4.

Start SketchUp. Use File>Import graphic. Trace over the outline of the roof top.

step 4

Step 5

Put SketchUp into parallel projection mode. Use the measure tool to check your dimension. As shown below, the wall measure 9025 units (mm) but should be 8250. Use the Scale command to size the model accurately - 8250/9025 = 0.914. Now any elements we add to the model will be dimensionally correct.



Step 6

Use offset and push/pull tool to create the wall at required height.

Step 5

You are now ready to use your SketchUp skills to create your model.

If you have SketchUp Pro or a plug-in to one of the earlier versions of SketchUp, it is possible t build 3D models in SketchUp by importing a DXF file exported from SketchUp.
