Learn how to combine multiple sketches into a single model, use datum planes to position sketches and the difference between pockets and holes. In this video, I design a paint can wall holder suitable for printing on any 3d Printer with a large enough build volume. Many 3d Printers from Creality, Prusa, Anet, JG Maker and Monoprice for example are suitable for printing models created in FreeCAD.

@MakeWithTech 3 года назад

Did the PIP style work for you. If it did it is faster for me to make additional FreeCAD videos. Unfortunately RU-vid does not seem to like FreeCAD videos as much as some other and they seem to get fewer views. However the viewers are quite supportive so I will try to increase the number of FreeCAD videos I produce. Feel free to goto forum.drvax.com and suggest some additional FreeCAD topics.

@striveupward Год назад

All of the Dr Vax videos are exceptionally well done. The "friendly", easy-going, but "excited" presentations are a pleasure to watch - and very instructional. CAD programs are inherently UNFRIENDLY; but Dr. Vax makes mastering FreeCAD very pleasant - one bite at a time. His very useful items are well chosen to be properly complex to introduce new features. Thank you very much. I also like the pip style. I appreciate that you say what you are GOING to do BEFORE you do it, and you go slowly enough so the viewer sees exactly where the mouse is pointed when an action is taken - and there is NOT wasted mouse "ramblings". Please keep up the great work. I am working on a prototype, and you have made it possible for me to make "small run", necessary components - which are NOT commercially available anywhere. Blessings.

@paulg3336 3 года назад

13:15 Tip: The datum plane does not have to actually be in contact with the face (e.g. 35mm) It can be offset from the face and the sketch on the plane for the holes can be pocketed across the gap and through the faces by specifying the correct pocket depth and direction. Of course, using the hole tool requires the position to be on the face to get the correct countersink

I've been trying to figure out how to do sketchcentric modeling in FreeCAD 019 and this showed up at just the right time.

@indigo0086 Год назад

One good way to understand the "flat" perspective the plane has is simply press 1,2,3 etc. When you change which plan you're focusing on, they all orient themselves the same way, and thus it's local coordinates are moved in such a counterintuitive manner if you're thinking about all the planes being oriented differently at once

@RemScanProducts 2 года назад

Just starting to learn FreeCad for use with a new 3D printer. Love your videos. Very understandable. I have a project that I can't seem to get a constraint to work. I have a circuit board with a hole in each corner that sits on the bottom of a 3D box. I want to use one of the holes as a reference point for making holes on the side of the box (vertical plane) for side connectors to the circuit board. How can I tell Freecad to measure from the center of the circuit board hole to the distance to the center of a connector so I can make a hole in the box? This way if I change where the board lies in the box, the connector holes on the side of the box will follow the board. Thanks again, Maybe one of your videos already explains this. John

I love your detailed and precise explanations, so rare on youtube, and thank you for taking the time to do this, I've learned practically everything about Freecad from you. But, there has to be one lol, I just can't seem to get that last bit of the dimple in the back plate, I think I've followed all your instructions, but I must be doing something wrong. One wee thing (I know I'm stupid) but could you give a deeper explanation of what you mean by 'switching on and off' the sketches & pads, please. My system doesn't seem to have that in any menu, that I can see. And I'm not following when you say "I'll just go back to my sketch", I seem to have several sketches - am I starting a new sketch on a different plane? Maybe you've already explained all this in another video, I'll just keep watching. I made my first box, thanks to your videos and I'm keen to try some more complex stuff now - like your WD40 rack.

@geertvancompernolle2586 Год назад

Switching on and off pads, sketches and so on is done by selecting them and pressing the space bar. AFAIK, there isn't a menu item or something like that. And yes, you can for instance switch off a pad by selecting it (that is, make it highlighted by means of clicking on the item) and pressing the space bar and still switch on its sketch (by also selecting it and pressing the space bar). See the space bar as a toggling function: pressing it ones hides the selected item, pressing it again shows the selected items. Whenever an item becomes "deselected", it is greyed out.

@braxtonmathas3536 2 года назад

I just want to say that your videos have helped me a lot with learning CAD design. One question i do have, and I may have missed something in some of your previous videos. But anyway, how do I actually edit a saved .FCStd drawing dimensionally if I want to change say the width of a pocket or the diameter of a hole? I have designed a part that mounts on my 3D printer as a filament guide and want to change a few dimensions and I just cannot figure out how to go in and change them. Any help at all would be very much appreciated! Windows 10 FreeCAD 0.19

@saschaschneider6355 3 года назад

Yeah, me again ;) First off, I like the video, thanks for it. I've learned about datum planes through it, something I hadn't used before. So thank you very much for it. But, always being that guy: as this isn't a beginner video it would've been better if you had named your constraints, like the holder's radius or the backplate's thickness, so that you can reference them in formulas. The way you've shown in this video results in things falling apart as soon as you change anything, which makes adapting your existing designs unnecessarily hard. You're doing maths in your head that you could let FreeCAD take care of. Like the placement of that plane or the width of the backplate. Why not just define it to be "HolderDiameter+10mm" or something to that effect? Then also name the thickness constraint and you can place the plane as "HolderDiameter/2-BackplateThickness" and stuff automatically gets adapted if you change anything

The hole in the bottom of the panel is say 10mm from the center of the main hole. Can I link two sketches to set the points at which I need the small pockets?

@saschaschneider6355 3 года назад

Yes, you can link parts from other sketches into the current sketch and then reference them. It's best you search for FreeCAD sketches tutorials so you can see how it's done for yourself

@2163716 11 месяцев назад

Hi. Thanks for a great lesson. Not sure if you're still monitoring this page but just a quick question in case. You create a second sketch to make the wall mount. When I tried that, it would not allow me to apply a pad. The only way I could apply a pad is by first creating a second body, then a second sketch. Has this been changed in recent versions of FreeCad or am I missing something? Please kindly explain why it allowed you to create a pad on a second sketch without first creating a second body. Thanks so much. Daniel.

@frognot672 11 месяцев назад

Up until seeing this video, I had determined to master FreeCad. Now seeing the clunky and counterintuitive process, I have decided it's a complete dud. It could be done so much easier.

I'd likely use OpenSCAD as well but you can make it easily modifiable in FreeCAD as well. Either base everything on a spreadsheet or name constraints along the way so that you can use them in formulas later on. For me doing both works best: basic measurements go into a spreadsheet and I name constraints as a shortcut for calculations.

@@MakeWithTech I agree, but maybe you do the same model in openscad -- and have fun with the countersunk holes ;-) (I think I'd chop it about a bit, to save plastic.) freecad is handy to apply bevels/fillets to imported scad files, but exporting from free to open, is confusing to me, too much multimatrix, which I normally never use.

@MisterkeTube 3 года назад

I hate having to state this, but looking at a tutorial like this and seeing how complex it is to make something this simple in FreeCad and how I would be able to do this in Fusion 360 within 1 minute with just a few clicks, without having to think about moving "data planes" numerically in some weird direction, just making 1 profile sketch with all geometry nicely defined and then extruding the 2 volumes needed from that sketch, then just creating a new sketch on the flat part to position the holes and with the hole command getting control over those holes ... then my choice to not (yet) drop Fusion gets reinforced. I'm sure a lot is possible in FreeCad and some things (like the list of constraints and the indications on which are over-constraining or how much freedom there still is) are better than in Fusion, but in general it just takes too much headache to design something this simple in it. Ex. What if I would want the pocket for the opening to hold the can to NOT cut into the flat part, but just "touch" it? In the main Fusion sketch this would be a breeze, adding a single constraint, but in FreeCad my head already starts to hurt trying to figure out how this could be done accurately (preferably without having to enter the same dimension manually again)...

@saschaschneider6355 3 года назад

You don't actually enter any dimensions twice. Irv chose to do it this way. You can reference any previously used dimensions and you can name constraints - and you can use formulas everywhere. Irv could also have used primitives, like additive/subtractive cylinders. Creating a circle in a sketch which you then turn into a cylinder by padding the sketch is more work than you actually need to do. Like, when placing stuff you can go =Cylinder.Radius (or =Sketch.Constraints.HolderDiameter/2 if you go Irv's route and name the diameter constraint accordingly) Edit: if you rename items FreeCAD is smart enough to update references. Like renaming Cylinder to CanHolder will update =Cylinder.Radius to =CanHolder.Radius

@MisterkeTube 3 года назад

@@saschaschneider6355 I've tried moving over to FreeCad a couple of times, but never succeeded. Only allowing a single area for padding/pocketing for me just feels so much less user-friendly than the multi-purpose sketches of Fusion. And every time I then need to reference in a new sketch some line/edge or curve from either another sketch or an already existing other part then I typically end giving up as FreeCad always seems to find some reason why what I'm trying to do would not be possible. When I start in CAD, I don't know yet all dimensions of the thing I'm trying to make. I typically want to sketch the big picture and then add constraints to make all parts fall in place and then start extruding or rotating those into the third dimension - then typically multiple bodies from that one sketch. FreeCad just breakss that (I think). Yeah, it's probably me not knowing how to use FreeCad properly, but Fusion is just so much easier in my eyes - I can reference any edge, vertex, plane, part, ... with a simple click, projecting or intersecting to get stuff into the sketch. There's probably also a lot I don't know yet in Fusion, but hardly ever does it complain that something I want to do, would not be allowed. I'd love an OpenSource CAD program that would give me the same usability, since Fusion's licensing is a Sword of Damocles above my head, but as said, FreeCad just doesn't provide that usability in my eyes (yet) ...

@saschaschneider6355 3 года назад

@@MisterkeTube you normally can reference any edge or vertex by adding it using the "x" command, which creates a link to external geometry. But tools need to be compatible with your own way of thinking and sometimes things just don't work out. Like I've tried to create stuff in Blender for years and it never "clicked" for me. FreeCAD had a learning curve but it was way closer to my way of doing things so I had more success there. Sometimes you just have to realize that something just isn't for you.

@haysoos123 3 года назад

@@MisterkeTube btw the multi-purpose sketch is really a practice that's not encouraged in CAD, even though you can do it in f360. If you do this a lot without care, it can lead to models that will break easily and make more complicated models hard to manage. Generally it should be one sketch = one feature. Sure, for simple stuff it might appear to you to be 'easier' but in actuality it makes getting to fully constrained harder, and it's harder to keep track of the features or make tweaks to a feature later down the line. Also, I find a lot of f360 don't do best practices in general, like getting to full constraint on a sketch.

@@haysoos123 It's a target group thing. F360 users don't really care about best practices, they care about getting usable results in the easiest way. FreeCAD cares about being a CAD program and therefore (generally) follows best practices, which makes it harder to use but you get results of a higher quality. The question is: as a home user, do you actually need the higher quality produced? Probably not, at least not for a quick 3D printing pipeline. Once you start making things that are more complex, mote intricate, that you're going to be working on for some time, that you're going to redefine and change more than once, THEN the complexity becomes necessary
