![]() ![]() The option to create a new cloud from the selection is also useful and should still be kept. Next, instead of always creating a new point cloud every time I confirm a selection I should be able to set a target point cloud that the current selection is moved to when I confirm it. There should also be ways to invert the current selection, deselect everything, and select everything. Instead of an extra button click to select inside or outside the 2D boundary every time a new boundary is drawn you should be able to set a global mode for the tool (add to selection, remove from selection, toggle selection) that affects all boundaries that are drawn. With that in mind this is how I would redesign the segmentation tool.įirst I would model it after the selection tools in Photoshop (or most other DCC applications). I want to send the individual selections to a few segmented clouds, maybe a "pedestrians" cloud, a "vehicles" cloud, and a "junk" cloud, or maybe I just want everything to go to the "junk" cloud. I don't, however, want to segment my input cloud in to hundreds of separate clouds. Doing this might require making hundreds of small individual selections involving thousands of clicks. Consider the common case where scans were collected outdoors and you want to segment out all of the partially scanned pedestrians or vehicles. ![]() Right now all the extra clicks required to select points and transfer them to a new cloud make it impractical to use except, as andrewod notes, for chopping out a few big chunks. I think there is quite a bit of room for improvement in the existing 2D segmentation tool to make it more efficient and user friendly. In fact you really need some 3d functionality for cleanup.Ī nice 3D selection tool would be pretty cool but coming up with a good UI might be a challenge. Select Binary STL as your output format, and choose where you want to save it.Andrewod wrote:The snippet tool is good for chopping chunks out of the cloud but you need a better tool for clean up. Once you are happy with your newly modified object, go to the File menu and hit Export. Once selected you can hit your backspace key on your keyboard to delete the part. ![]() Hit the Select button, set the size of your brush, then paint the area you wish to select. If there are elements of the object you wish to remove then you can paint the selection using the Sphere Brush or Lasso. Once you are happy you can accept (choose the defaults to begin with then play with the options). ![]() Again, in Edit/Transform, choose Plane Cut, then drag the arrows until only the part you need is visible. We are going to use the Meshmixer Plane Cut make a lateral cut, splitting the top from the bottom. You can pull on the various axis points, or just type 90 in the Rotate X box in the inspector. I like to make my object stand up in the correct orientation, so I go to the Edit button, and select Transform, then I rotate so it is the correct way up. When you start Meshmixer it will ask if you want to import a file or import pre-made objects, go ahead and import your STL file. It needs surprisingly few resources for simple objects, but obviously the more power your system has the better. Meshlab delete mesh mac#You can get Meshmixer from Autodesk for Windows and Mac (sorry Linux!) here. Let’s look how simple it can be in this quick video and tutorial! That is where Meshmixer comes in, it can load, modify and even delete parts of existing STL models, quickly and easily, and then export for 3D printing! Meshlab delete mesh download#Sometimes you can find an existing STL file to download that is almost what you need, but the simple modification tools of Simplify 3D or other slicers don’t cut it. Using Meshmixer takes your 3D printing superpowers to the next level. ![]()
