Join Jim LaPier for an in-depth discussion in this video Flatten command, part of AutoCAD for Mac 2018 New Features.
- [Instructor] Next up I want to take a look at the new flatten tool. This is a welcome tool for any 3D users, but I'll show you that there's also another way that this can be used just to help clean up your drawings. I'm going to walk through the tool first, and then we'll talk a little bit about what exactly is happening. I'm going to switch over to my top view of my 3D model, and then I'm going to go find the tool. It's available in a few locations, including under the drafting tool set here under the modify panel. I'm going to select my objects and press return. I'm asked if I want to remove any hidden lines in this particular model.
I don't really have any hidden lines in this view, so I'm just going to say no, and that's it. It doesn't it did too much, but if we change our view we can see we now have a completely flat view of our part. I'm going to undo back until I get my 3D model back. Right about there. There we are, and I want to see what else this tool can do. Not only can you do this using straight-on views like front or top, I can even do it in the view that I'm currently in. So again, I'm going to go find the tool.
It's also available here under modify, under flatten objects. I'll select the tool, press return, and this time I'm going to say, yes, go ahead and remove any extra hidden lines and there we are. It doesn't look like it's changed all that much, but if we now look at it from the side, we can see that yes, this is indeed a flattened view. So not only can we flatten any 3D objects that we have, this is also very useful for cleaning up our drawings. If you've ever received a .cad file from someone else, and they've accidentally changed the Z value on certain objects, you've got things kind of floating out in space above the work plane, or they've altered the thickness of items, you can use the flatten tool to bring everything back down to a zero level.
So not only useful for 3D tools, but a great way of cleaning up your drawings as well.
