![]() The benefit of top-down assemblies is that we can reference other sketches and parts, so if we change one thing the other features or parts change accordingly. In Fusion 360, each new document you create can be treated as an assembly, which is why you’ll never see “create new assembly” under the file menu (but you will in Autodesk Inventor and SolidWorks). Fusion 360 falls in the top down assembly category, although technically you could also use Fusion 360 as a Bottom-Up assembly. On the other hand, we have “Top-Down Assemblies” which means you start with an assembly file and build all your parts within the context of the assembly. If you change one part, you’d better know which other parts will be affected by the change and make sure that they are also updated accordingly. together because you designed them to fit together. There is NO link created between parts, so the parts fit (keyboard shortcut “f6”) Makes the current file fill the screen. The essence of the “Bottom-Up Assembly” Technique is that each part is created individually, and then all the parts are inserted into an assembly document and constrained to each other. If you’re coming from Autodesk Inventor or another CAD program then you’re likely already familiar with it. This is the traditional assembly modeling technique. Let’s take a look at Re-arranges screen to look at selected object. Bottom-Up VS Top-Down Assembliesīefore we dive right into the world of bodies and components it’s important that you understand the difference between Bottom-Up Assemblies and Top-Down Assemblies – which will help you better understand WHY Fusion 360 is set up the way it is. Whether you’re an experienced CAD user coming from Autodesk Inventor or SolidWorks, or you’re completely new to the world of 3D modeling, this is the place to start.īy the end of this article, you’ll have a solid understanding of the difference between Bodies and Components and we’ll talk about the dubbed Fusion 360 Rule #1 and Rule #2. Plus, check out our Inventor Tips Playlist on our YouTube channel.Understanding the difference between bodies and components is an important first step to becoming proficient in Fusion 360. ![]() Interested in learning more about Autodesk Inventor? Learn how to project geometry in an assembly and update multiple iProperties at once in our previous blog posts. Watch the video tutorial below to see in action how to remove the material of a part in an assembly using the outside surface of a mating part in Autodesk Inventor. Step 6: If a lump or void remains, you can remove it with the Delete Face command. ![]() Step 5: With the Sculpt command, select the surface you would like to remove. Step 4: Navigate to the Surface panel and select the Sculpt command. Then, click on the solid that will be used for creating the cut. Step 3: From the Copy Object pop-up, select Body. Step 2: From the Modify panel, navigate to Copy Object. Step 1: Edit the part you’re looking to remove the material from. We’ll be demonstrating the following steps: This can provide immediate time-savings to your designs and prevent you from having to create 2-3 sketches to achieve the same result. In this Autodesk Inventor tutorial, we’ll be looking at how to subtract one solid from another in an Inventor assembly by using a mating part. 27, 2019 by Manufacturing Applications Consultant, Dave Breiner
