![]() Click these buttons to deal with the relevant issues, they should fix themselves!ĩ. There will likely be multiple items such as “Reversed Faces” and “Stray Edges” that will have a button next to them that says fix. Select one of these groups and go to Tools > Solid Inspector.ĥ. Note: Grouping the model helps your computer not to crash when it tries to clean up the entire model.Ĥ. If you make a mistake while grouping, you can ungroup by selecting the group and right clicking again, but selecting Explode instead. In order to group some elements, select them and then right click on them, selecting Make Group. Note: You probably shouldn’t do this while actually working on your model making large changes, as this will slow down the software significantly.ģ. Select Window > Preferences, then change the precision to as high as possible. Layers don’t work the same in SketchUp as they do in other programs like Rhino, instead use groups for similar functionality.Ģ. Note: If you’re going to do any modelling in SketchUp, leave it all in “Layer0”. Don’t scale the geometry down to size just yet - this will cause a lot of issues especially in the clean-up process. Install the extensions above in the given order. Open up SketchUp, select Window > Preferences, then open the Extensions tab.Ĥ. Note: Although this guide will go through some of the functionalities of these extensions, if you ever get stuck or want to learn more about the extensions there are some excellent video and article tutorials on the pages linked.ģ. These will help us to fix the model so that it’s ready for 3D printing, and help us cut the object into the right shape when we need to. There are four extensions we need to download: TT_Lib2, CleanUp3, Solid Inspector2, & Zorro2. Follow this to learn how to set the 3D model up for printing in the 3D printing software.Ģ. Follow this to export your model into a format acceptable to 3D printing software. Follow this to slice your model up into manageable chunks for the 3D printer. Cleaning your model throughout the process makes the rest of the steps much easier. Follow this to install the extensions necessary to follow the rest of the steps. If you’re more experienced with another tool, feel free to follow along and apply similar techniques, although you’ll have to figure out some of the specifics on your own. We’re going to use SketchUp because it’s easy to use and learn. Having said this, SketchUp isn’t the only way to achieve this result - you can also go through Rhino, or some other piece of CAD software. stl file! SketchUp will also help us to clean up the model and make it ready for 3D printing. Revit can be directly exported to SketchUp, and SketchUp can export to an. stl file, which can’t be officially exported from Revit, and the user-distributed tools for doing so often are out of date. Why SketchUp? If you’ve had any experience with 3D printing, you’ll know that your file has to be in a specific format before it can be put into 3D printing software. Need to print a site model? Here’s a practical guide that will walk you through the basic steps, from Revit to print, via SketchUp. How to 3D Print Your Site Model Using SketchUp
