Hi, I’m Michael. I’ve used Revit for seventeen years, and for a long time I’ve also made and sold Revit window and door families. What I love about SketchUp is the opposite of Revit: you just model, and nothing makes you decide what something is before you draw it. I want both. I want the tools and…

Question: How does the tool know if it’s a wall and how to behave when it encounters a T or even corner?

@MikeWayzovski good question. These tools came out of my work on the Aplo Wall, which is still in development. An Aplo Wall is a real wall: it knows its layers, each layer’s function and priority, and where its core is. When two Aplo Walls join, the structure decides the result. Higher-priority laye…

Well, I got along well with Profile Builder , which in a way can categorize multiple Profiles into Assemblies as a layered wall the way Revit does. That extension also has a hole tool to cut openings with those layered walls, btw. The moment you start categorizing, that’s the moment you start loosing…

Aplo 0.4.0: rounded and chamfered corners, in plan and in elevation Our house will be built on a slope, so this week I needed to model a ramp : landing, ramp, landing, with a transition at each end so a car doesn’t ground on the edge. Up to 0.3.1, Trim/Extend to Corner could only make a sharp corner,…

v0.5.0 is out, with a new free Modelling tool: Lengthen This one came from something that kept bothering me. Making a line longer in SketchUp is easy as long as it runs along an axis. As soon as it doesn’t, I lay a Tape Measure guide along it, Move the end along the guide, and delete the guide again…

v0.6.0 is out: drag in Lengthen, and gable walls After v0.5.0, @Wo3Dan pointed out that SketchUp can already lengthen any edge in its own direction, off axis too, and with an exact value. Thanks, I tried it: grab the end with Move, lock it to the line with Shift and type the distance. It works, but …
