How to modify an STL or mesh - 3D design for 3D printing pt7

To get the best out of 3D printing, it helps if you can design your own parts. In this tutorial series, we will learn to use a free 3D CAD program to do just that.
In this episode, we look at situations where a model has already been designed that we want to modify, but the author has not made source CAD available, so all we have is an STL. Onshape has improved its functionality and it’s now possible to add and subtract geometry from STLs and other meshes. We also briefly look at working with a 3D scanned mesh.

For years I've tried (and failed) at bringing STL files into Solidworks. Meanwhile in another corner of the universe, Tinkercad quietly makes editing STL files natural and easy. No more fussing with long imports that simply don't work, or that produce non-editable surface-only models. In Tinkercad you simply import the STL and in a few seconds you've got a nice model ready to cut, add-to or resize. No goofy triangles here, just solids the way you like it: clean, visual and full detail. As a CAD product, Tinkercad is a toy, but for this specific job it's absolutely amazing. And FREE!

A lot of STLs were exported from Fusion360 with ultra high definition settings, resulting in the entire object being tessellated just like the last import example in your video. Most apps, even Fusion360 itself, perform badly and become sluggish when importing such high poly objects. Perhaps a video on how to simplify the mesh and making the object more app friendly without loosing accuracy or sharp corners would be helpful.

@1:55 if you want to measure the distance between the center of two holes, measure the inner distance and the outer distance and calculate the average. If you do it with the “floating tips” you most likely are off by a couple of 0,1’s because if you measure something like 4,6, you probably think… nah… it must be 4,5 while it actually is 4,7. Designers don’t always use “nice numbers”.

Hello :) Quick caliber pro tip: to get exact center measures between holes, use the back tips (like in the video), first inside one hole, remember to write the hole size down -> then (re)set to zero while still measuring the hole size -> then insert the back tips into two holes, then measurement the caliber now shows is the exact center to center distance

Amazing video, as always. I use Solidworks for something similar, but instead of just changing the mesh with added solids like here, I have to redraw the full part and then edit it to how I would like it to be, with permission from the original creator of course. I'm glad that this style of modifying/reverse-engineering got more recognition. For simpler parts, it's no issue, but for certain hobbies I'm into where there are some extremely odd rounded surfaces, I'm still having an incredibly tough time.

I use F360. I gave up dealing with other people's STL files a long time ago. I rarely print them and no longer try to modify them. Both can be exceedingly frustrating for a lot of different reasons. Once you have the skills to draw whatever you need in F360, Onscape or any other 3D CAD program, it is far faster and easier to just draw the thing from scratch. If you don't have the skills to draw your own, Michael's video has some really good tips and workarounds, but it's still likely to be a frustrating experience. The best experience is a well designed model in STEP format. Some designers provide them. Some don't. Usually the better designers do. In a few cases, I've emailed the designer asking for a STEP file explaining how I want to modify it and they have sent me the file. If you do that, be sure to post a "Make" on the site crediting the original designer.

It's not sponsored, actually. In the first video Micheal considered several different options for CAD platforms before settling on this and he goes through the thought methodology for the entire process. This is one of the most transparent and independent channels I've ever seen in regards to content; requiring companies to accept his own review agreement before accepting any free products and being very, very clear when anything was provided by a company/manufacturer.

This may be too simple, but I can’t figure out how to make an object shorter. For example, I want to take a table design but make it 20cm shorter in length. Is there an easy way to do that but keep the legs, skirt, etc in tact?

@harvey66616 Жыл бұрын

There are different approaches, depending on what exactly you mean to do. The simplest is to use the "scale" feature, which allows you to apply scaling factors (one for each direction) to a shape/body. This will change the whole object though, included e.g. the thickness of the table-top. If the section of the shape you want to make shorter is uniform, then you can split the body at two planes representing the distance you want to remove (e.g. making the planes 20 cm apart), to make three pieces, then delete the middle piece and move the remaining two pieces together. If for example your table legs are tapered, then that won't work. Instead, you can split the shape just at the bottom surface of the table-top (i.e. split the legs from the top) and apply a scaling to the legs only. If you apply a non-identity scaling factor (i.e. something other than 1.0) only to the vertical/length of each leg, then the height of each leg will change without affecting the width.

I find most imported STL files are scaled 10x larger than the item - why is this so? The number of vertices makes working with them horrific. Any advancements by design software to more effectively modify STL is very helpful I think given the enormous libraries of complex parts being grown online. I think frequent repetition occurs in the design community because remixing a design is frustrating.
