Placing Wind Turbines with my Random Tools Extension

Placing Wind Turbines with my Random Tools Extension

https://www.youtube.com/watch?v=aHuqTEaOtI0In this tutorial I use the example of a large wind turbine array to show how useful my Random Tools extension for SketchUp can be in making things look more realistic - by rotating turbine blades in this case.StepsThe three main steps to prepare a component for use with SketchUp's Random Tools extension are also illustrated below. For this example it is best to use a component, not a group. As I show in the video, grouping the rotor blades will not allow the extension to properly place its center at the rotation axis. Therefore, start by selecting the rotor blades and the axle and using the "Make Component" tool. In the Make Component tool, we then need to place its axis at the center of rotation. Click the "Set Component Axis" button and then place the axis as shown below. Now you can use the "Randomize Objects" tool from the Random Tools extension to rotate the blades...

Attractor-Based Scaling with Scale By Tools

Attractor-Based Scaling with Scale By Tools

https://youtu.be/QRle49KTceYA new feature of my Scale By (Image/Attractors/Equation) Tools SketchUp extension is the ability to transform (scale/rotate/move) objects by proximity to other objects ("attractors"). Not sure what this means? Check out the tutorial video above that explains the basic functionality.You can learn more about this extension on its page and the reference manual. ...

Just Published: Two New SketchUp Extensions (Random Tools & Scale By Tools)

Just Published: Two New SketchUp Extensions (Random Tools & Scale By Tools)

I just published two new SketchUp extensions that were both based on Ruby code that was either previously posted on this site or in my book, Architectural Design with SketchUp". Random Tools Ever wanted to place large swaths of randomly-arranged grass in SketchUp as shown in the image above? Have you been frustrated by textures that repeat a bit too much on copied wood boards? Do I have an extension for you...Read the announcement Scale By Tools Using the provided tools, you can scale, move or rotate objects based on an image or a mathematical equation. For the equation, you can choose between a trigonometric function or a power function. It is also possible to use image data to push/pull faces or move vertices, which can be useful to create ripples on water or a heightfield topography.Read the announcement...

Randomized object placement on faces (Snippet)

Randomized object placement on faces (Snippet)

This collection of small script snippets presents handy little routines that are usually too small to put into a proper extension. Use them with the Ruby Code Editor (just paste the code and hit “run”) or make them more permanent as a menu item (see Appendix D in my book).At least when it comes to creating realistic-looking vegetation in SketchUp, it is important to be able to randomly place, scale, and rotate objects. Nothing looks worse than a "sterile" copied/pasted row of trees, for example. Of course, this applies to other objects as well, like e.g. a shag carpet or fur. Let's fix this with today's code snippet.Typically, the objects to be placed would come in the form of components (trees, grass, bushes, as in the image above). And those then need to be placed somewhat randomly on one or more faces in your model. A good example for that is a lawn, as I discussed in Chapter 5 in my book. As I mention...

Patterned Panel + Bending Extension = Cool Candle Holder

Patterned Panel + Bending Extension = Cool Candle Holder

Now that the days are getting shorter, it may be a nice home decorating idea to create a decorative candle holder. Having the powers of SketchUp and computational design methods as well as 3D printing at our fingertips, it does, of course, make sense to create something more interesting than just a boring lampshade.This brief example uses the patterned panel exercise from Chapter 7 to create the basic geometry. Of course you can replace the sinusoidal wave pattern easily now with another beautiful function, or you could even have the cutout pattern generated based on colors in an image, which allows you to make it look like a logo, landscape, etc.Since the resulting shape needed to have the pattern cut into a curved surface, there were basically two approaches: 1) create a curved surface and place the geometry onto it by arranging it radially (and then subtracting it), or 2) creating the panels flat and then curving them. Also, this...
