You may need to employ a mix of Cover and manually drawing lines to get faces to appear.Īlso check the Display Back Faces diagnostic (shortcut DB), which will highlight the backsides of faces in red. Again, this is most useful with Monotone Mode (shortcut DM). Try using FormIt's Cover tool (shortcut CV) to try and automatically draw the face that is missing.Solid-looking geometry may be missing a face or two, and once those faces are drawn, the shape is considered properly solid/watertight Standalone faces that are 2D should be extruded into 3D solidsįaces inside of solids that do not contribute to the solid walls should be deleted These edges can be addressed in a variety of ways, depending on the situation:įreestanding edges not attached to anything should be deletedĮdges that overlap other edges should be deleted You'll see red lines drawn that indicate where the shape is not watertight. Try using it with Monotone Mode (shortcut DM) to make the lines more clear. In FormIt, you can use the Display Watertight visual style (shortcut DW) to display watertight issues in the file. Tools like Extrude work best with solid geometryĪdvanced tools like Shell Solid only work with solid geometry Non-solid objects are more prone to failure and more difficult to work with in Revit - so we generally recommend ensuring geometry is solid.Other applications like Revit and 3D printer apps require solid geometry

Solids best represent real-world 3D materials and assemblies and help organize the model In general, it is best to work with solid geometry in FormIt for a number of reasons:

In some cases, even files of smaller size are more complex and may need to be split into smaller pieces. Rule of thumb: Anything larger than 100 MB, you should consider breaking up into mulitple models BEFORE importing into FormIt. Here are a few rules to remember when working with SketchUp data: Beware of Huge Files
