SketchUp Shortcuts: Handy List

A SketchUp user who found my long-ago SketchUp projects on the Math Forum (those projects are no longer hosted there), recently told me about a one-page site she created: http://sketchupshortcuts.com/ Here’s a peek:   I’m a big fan of using shortcuts, and it’s sometimes hard to remember what key does what. You can set up […]

MSPhysics and the Ames Illusion: Part 3 – Go!

In Part 2 of this series, I left off with the room and person, ready to animate in MSPhysics to see the Ames Illusion. Here they are:   Before getting into making the person slide across the room, run the simulation to make sure the person is stable and won’t topple over because of the […]

MSPhysics and the Ames Illusion: Part 2 - MSPhysics Prep

In Part 1 of this series, I ended with the distorted room that would house the illusion itself. It looks like this:   But in the saved view, the back of the rook looks more like a regular room:   In this post, I’ll show how to set up the room to work in MSPhysics, […]

MSPhysics and the Ames Illusion: Part 1 - Room Setup

I recently wrote up a kids’ project for Beanz Magazine on how to create the Ames Illusion in SketchUp. (If you have kids, or are a kid, check out my last Beanz project on jigsaw puzzles.) What is the Ames Illusion, you ask? It’s an optical illusion in which a person appears to grow or […]

Sculpture Modeling - Organic Shapes, Part 2

In Part 1 I showed how I modeled an organic sculpture using a few neat SketchUp extensions. That project consisted of two sculpture models, and here’s a description of the second one. My model appears in this rendering – it’s at the top left corner, along the sidewalk.     The idea was that the […]

Sculpture Modeling - Organic Shapes, Part 1

I recently had a fun design job with a local architect. The idea was to make a conceptual model that loosely resembled a specific sculpture. The sculpture model would be placed in a SketchUp model of a new, mixed-use project, to show in context what a similar art installation would look like.     (The […]

If you have kids who like coding, robots, Minecraft, 3D printing, electronics – please check it out. There’s a print and online version, and my own kids have spent time enjoying many of the […]

PNG Trees: Part 4 - Adjust for Shadows

The other posts in this series focused on how to create models of trees that have transparent background and always face the camera. This last post in the series is about solving the problem of shadows. Here’s a face-camera tree:   And here’s the same tree with shadows turned on (menu: View / Shadows). Because […]
