While it may be obvious to FreeCAD developers that a pad operation creates a single solid (my guess), from the user’s perspective multiple solids are supported because a sketch with multiple non-intersecting circles can be padded.Ī user-centric error message like “Padding of intersecting objects is not supported.” would have saved me minutes of frustration. It took me quite a while to accidentally trigger the tool-tip, and then a few more minutes to figure out that this error was caused by the intersecting circles (the actual sketch was much more complex). When mousing over the object tree view, there’s a tool-tip saying: “Pad: Result has multiple solids. The report view displays the kafkaesque message: “Recompute failed! Please check report view.” I often get stuck with recompute errors and have no idea why and how to fix it.Įxample: Sketch two intersecting circles. The only downsides are the limited import and export options in the free version.Īnd another input for the FreeCAD devs: Report errors in a way that a user understands without knowing the inner workings of FreeCAD. Draw the hole on one, and then when you start drawing on the other, you’ll have it as reference, no need to set it up as a reference, it’s just there in your 2D drawing plane. Working with multiple parts is a charm, two different parts next to each other and both need a hole that line up? Super easy. Next pull the edges to make a round or chamfer. Draw a circle on it, pull that down to cut a hole. You draw a box, put in the dimensions, pull it out into the 3th dimension with a size. But also different from the freeform TinkerCAD and blender, where it’s hard to get accurate dimensions in. It’s very different from the “think before you start drawing” constrain based modeling. My goto software is DesignSpark Mechanical. Want an assembly? Well screw you, you’ll have to deal with broken extensions crashes and frustration. But it fails at anything beyond that, which is why the tutorials also only do part modeling. WOMP looks like an improved TinkerCAD, but not really the same usecase as FreeCAD. Posted in 3d Printer hacks Tagged cad, freecad, parametric design Post navigation If you want to take a step further into parameters, we’d suggest following up with this video. If you want a longer series, we’ve looked at a few. But it is a look over the shoulder of someone making a practical design using simple methods that are perfectly fine for most simple designs. It might not even be the first one you should try. Is this the only FreeCAD tutorial you’ll ever need? No. However, he shows how to incorporate external geometries when working with multiple sketches. With proper constraints, you would simply adjust the size of the part, and everything would move to the proper place.īecause he sticks to simple constraints, he also doesn’t show construction geometries. For example, instead of just plugging in measurements for how far away things are from the center is a problem if the size of the part ever changes since you have to remember to change it everywhere. However, once you get your feet wet, you’ll want to explore more sophisticated constraints. You’d probably still want to have someone explain details to you before you attempt it yourself.įreecad’s constraint system can be confusing, and deliberately sticks to very simple ways to use it. If this were riding a bike, this tutorial would be akin to watching someone ride a bike to pick up tips. asserts that Freecad is simple, and provides a simple walkthrough to create a part in the video below. Remember learning to tie your shoes or ride a bike? Like many things, that’s easy once you know how to do it, but seems impossible before you learn.
