PlusSpec Pro Architect & Builder


Transform the way you use SketchUp with PlusSpec

PlusSpec simplifies Sketchup by automating repetitive tasks whilst increasing output, particularly for those who’ve never used Sketchup before or for those who’ve never created a BIM or VDC project.

An organised model is the key to viewing all parts of a project, from finishes through to structure. When you use Plusspec and our included library of components, Sketchup will never slow down or lag.


Why is Plusspec so fast?

Because PlusSpec automates layers, scenes, styles and structure creation, and creates scenes not only for 2D representation in layout but also for structural analysis, visual clash detection and more.  


Create engaging models that will wow your clients - without the time or the effort. Draw complex roofing, trusses, joist, concrete, wood framing, stairs and more, all in just a few clicks! Best of all, everything is categorized and neatly laid out in a detailed bill of quantities for either feasibility studies &/or detailed estimating.


PlusSpec is easy to learn and use and it’s designed for people who are too busy to spend hundreds of hours figuring out how to drive BIM software. Every tool has built in video tutorials, so you can get good fast.


For Architects and Designers

Immerse your clients in interactive 3D models and give them cost insights to your design right from the get-go. PlusSpec has a scene creator that delivers more than just 2D plans - it gives insight to buildability. Eliminate the communication barrier with builders and estimators by handing them material break takeoffs that generate as you create.
