Our advice is to import all objects with the “Make all surfaces double-sided” option off. So, to simplify 3D models of these objects and decrease their size, faces of invisible object parts are not needed. Adding faces leads to increasing the 3D object size, which results in increasing the document size. Most of the objects can be viewed only from the outside, like a sofa or any other furniture item. The lack of these faces will make some parts of an object invisible. The app applies color and texture to these faces to make them visible.īut, if you need to look at the box from the inside as well, each of its sides should have two faces, inner and outer, to make them visible. Live Home 3D creates faces for each side. When you import a 3D model of a box and look at it from the outside, you will see one side of each surface. Make All Surfaces Double-Sided to Avoid Invisible Surfaces When applying the materials to one cube side, all sides will get the new material. If the cube is imported again with this option activated, it will have the same look, though the 3D model will differ.It is possible to change the material of any cube side. If the sides of the cube have the same material, and this option is off, all the sides have the original material.If the cube has the same material on all sides: If you switch this option on and off, the result will be the same. If the cube has different materials on each side, it has no similar materials. Below is a short explanation of how this works with the two cubes. This optimization limits application of different materials to separate model parts. Read more about Bonnie.Remove excessive details from the model to simplify it and increase the rendering speed.

(Of course, if you did want to change the sideboard’s size, or anything else about the sideboard, you could edit the sideboard component and make your changes within the edited component.)īonnie Roskes has been writing tutorial-style projects on 3D modeling software, primarily SketchUp, since 2001. The sideboard measures 5′-3″, and will remain at that size no matter how you resize the room. So here’s the new and improved, post-resize room, with everything looking more reasonable. So if you created your own sideboard, saved it in its own SketchUp file, and used File / Import to bring it into another model, that sideboard would also not get resized when scaling. This applies to any model not created within your original model. This is by design – it’s assumed that imported components have accurate dimensions (which is not necessarily true, depending on what you find in the Warehouse), and SketchUp doesn’t want to mess with those models.Įxternally-loaded (imported) components don’t necessarily have to come from the 3D Warehouse. So everything in this model will shrink except the sideboard. When prompted about the resizing, the message lets me know that externally loaded components won’t be affected by the resize. The long wall measures 137′ – a tad long. ![]() So I need to use Tape Measure to shrink down the room. ![]() Resizing Internal and Imported Components I assume that the sideboard was modeled by a competent person at KARE, so the problem is me: my room is too big. When I import the sideboard, it’s clear that something is off – either the scale of my room or the scale of the sideboard. I used the Get Models tool to find something that will work, like the striped sideboard by KARE in the top row below. Now say I want a sideboard in the room but don’t feel like modeling one from scratch. And everything in this model was created in this model – nothing imported from elsewhere. ![]() No loose geometry, which is the right way to model in SketchUp. So now I have two groups (room and table) and four components (chairs). I made the table into a group, and made the chair into a component which I copied three times. The rest of the model – the table and chair – consists of loose objects. The Outliner lets me know that this model contains one group (the room itself). I didn’t pay attention to scale and dimensions, which will become clear in a bit. ![]() I also have a basic chair and table, created from scratch in the same model. In this very simple example, I have an empty room (two walls and a floor), which I’ve made into a group so that other objects won’t stick to, or otherwise affect, the room. This post also discusses using Tape Measure with groups and components. In Part 1 of this series, I showed how to use the Tape Measure tool within groups or components, to resize only specific objects and not the entire model.
