Using images for scaling and geometry patterns in SketchUp

Using images for scaling and geometry patterns in SketchUp

This post was actually inspired by a question in my Basecamp presentation: Could we use images to create or modify geometry in SketchUp? As it turns out, this is actually quite easy since SketchUp version 2018.This year's version of SketchUp includes a new class in Ruby, the ImageRep. Contrary to the regular Image class (which you can use to work with images as entities in SketchUp), the ImageRep class goes further and allows you to look at images on a pixel by pixel basis. This is basically what we need to be able to read pixel color values and then use those to create or modify geometry. Want to use this without coding? This script is also in one of the tools of my Scale By Tools extension. As you can see in the code snippet below, this is reasonably straightforward once one figures out the basic geometric behavior. The code even stretches the image by the (x and y) dimensions of...

Pulled Brick Design Options

Pulled Brick Design Options

I came across brick wall designs today where the architects were considering various options with pulled bricks. This design approach has been used before in many different ways but the basic principle is always the same: In a brick wall that is dominated by stretchers, you insert strategically placed headers which then protrude a little bit beyond the brick wall surface. This creates a very nice pattern with interesting shadows. The first image below shows such a design in a SketchUp model:Given that in reality these are placed manually it may be reasonably easy (and therefore not too costly) to vary the extend of their extension beyond the surface and thereby create more interesting undulating patterns. One such pattern is shown below:As it turns out, this is very easy to do by simply modifying some of the scripts from Chapter 7 and combining coding with a carefully created SketchUp model. The secret for success is having a component type (the...

Making replacement parts with SketchUp is so easy!

Making replacement parts with SketchUp is so easy!

I recently had the need to replace a broken knob on our dryer and instead of tracking down the original replacement part, I 3D printed the knob from a SketchUp model I made in a few minutes. Check out my blog post and see how I did it:https://alexschreyer.net/sketchup/dryer-fix-made-easy-3d-printing/...

Second edition of “Architectural Design with SketchUp” is now available!

Second edition of “Architectural Design with SketchUp” is now available!

I am very excited to be announcing the release of the second edition of my book "Architectural Design with SketchUp" today!For this edition, I went back through the text and updated and improved a lot of content. As before, my main goal was to keep it relevant for as large a variety of SketchUp users as possible and at the same time provide thorough yet easy to follow examples and tutorials.I am also very excited to announce a completely new chapter on physically making things with SketchUp that includes 3D printing, CNC cutting, and other techniques. Lots of fun stuff!As before, this second edition will use the companion website at http://sketchupfordesign.com/the-book where you can find free sample chapters, videos, references, 3D models, and tutorials.There are also now over 30 videos that accompany the book and can be accessed using the instructions in the book.Interested in getting the book? Check out Amazon or Wiley.Here's the official press release:3D Modeling in SketchUp and Digital Making Come Together in Second Edition of “Architectural...
