Very, very helpful, thank you. I've been watching freecad for many years, but I'm getting ready to move over to it for my work (PCB design using KiCAD)
MEEEEOOWWWW????? I am fighting had to understand F-CAD ... I think your videos are great ... but ... I don't know ... I am too dumb!! WTH are these WorkBenches ???
If you're unfamiliar with the workbenches, I would say only use part design and model from there. Think of each workbench like a different set of tools. Part design is the set of tools you need for making the model. Need special tools to make curvy shapes? Curved Shapes has tools for that. Need special tools to make gears? FC Gear has tools for that. Etc. Focus on getting good at part design and the other workbenches' tools and working between workbenches will start to feel more natural.
I would sure like that! I get a lot of people asking to not use hotkeys, so I try to keep it somewhat standard to not confuse viewers. But If I were to set my own, I would put everything on the left hand to make it as two handed as possible, focusing on sketch constraints. I loved how the hotkeys used to be, so out of habit and the sheer brilliance of how they were setup, I would use a similar setup to what existed. My main ones would be- h-horizontal v-vertical shift+h-horizontal dimension shift+v-Vertical dimension e-equal s-symmetry r-radius e-extrude r-radius
That's a tough one- I get people telling me to use hotkeys because they want to know the best workflow. I don't think there is a way to satisfy everyone, but I'll keep trying to find a way that's best.
@JokoEngineeringhelp I really love how you mentioned design intent, and also how practicality of manufacturing changes from metal machining to 3D printing! I'm sure there are many 3D printing hobbyists and professionals who will appreciate those mentions.
What degree of tangency is between surfaces? Can you control it? If you create plastic part, would the edges be visible as ridges? Or what about applying the zebra light(does FC even have it? I cannot find any video about it).
When I do spreadsheets (and internal naming of constraints) I use a system like this 1. all lower case is a calculated value 2. Capitalized is a User Entered Value (dimensions) 3) All-Caps is a Value that used to determine a whole host of results (like a system Variable) example: VOLUME is the desired volume of an object which will in turn be used to calculate dimensional values to get it. Height or ExitHole1_Diameter, etc would be values u want the user to give. While 'wall1_thickness' is a value set by calculation OR by reference The reason for this is so that in spreadsheets and while digging thru files I can recognize those constraints that are due to human error and hose that are done automatically.
Brilliant video, really enjoyed! Had to try my self in freecad. The hexasphere was the hardest to replicate. But once completed, I understood how the shape actually look. For 3D-printing splitting the model in two identical halves one discover that the modeling could actually be done by just doing 2 180 degrees revolves. Anyway, thanks for the video, love your channel! Cheers from Norway, FreeCAD lover.
Thanks for the tutorial. It was very helpful. :) BTW: For me the clone button (at 2:29:37) looks like a sheep. I think it refers to Dolly, the first ever cloned animal. Which was actually a sheep cloned in the year 1996.
As usual, just what I needed. I'm mounting a portable air conditioner in my van conversion for summer travel, and needed to both replicate the exit air duct that attaches to the unit, but also create a custom set of interlocking sections of "piping" down to the hole in the floor I will vent out through which I will insulate on the outside, as well as a custom pass through there that the pipe attaches to, and that attaches to the flooring and has a screen mounted inside to keep critters from wandering in. All will be custom designed. Learning FreeCAD has given me the freedom to invent at will with my 3D printer and I have more ideas than the time to spend on them with other things going on all the time! I can highly recommend it to any hobbyist with a 3D printer. They may find, as I did, that getting the basics under your fingers and THEN setting a goal to create a pretty complex part will PUSH you over the edge of confidence with it. My goal part was a "cart" for a window actuator in a motorized car window: the part that rides up and down in the curved track, which the steel cables pull up and down (with the window attached) to open and close the window. These are somewhat a "planned obsolescence designed part" as they will break after years of use. Creating it involved two Boolean cuts (one for the curved shape of the track it had to smoothly ride which I think was something like a 5' radius curve!) as well as precise internal cavities for the cables to mount into at the right tension with their springs. Along the way, I learned to do test prints on just a cut down portion of the model to save time and filament to check fit both for the track and the window "pin" that holds it. Works perfectly in my son's car, and now I have a model I can print, or mirror to print for any of the 4 windows! Quite a feeling of empowerment. So far, PETG is holding up fine in the car, but I have ABS and ASA I can reprint in if I deem it failed from heat exhaustion. My best CAD friend is a $3 plastic caliper from Harbor Freight, actually two of them: one in the garage, and one at my computer. I have a battery one that's more precise, but I find unless I'm doing absolute minute precision, and with some experience knowing how filament will expand slightly in your prints, I get all the precision I need and don't have to worry about batteries. Once you "think" in CAD terms looking at or imagining any new object (pad here, pocket here, etc.) it really opens up a whole new world and your channel is on my short list to plug any knowledge gaps...
Those sound like awesome projects. I have hot summers where I'm at, I could use a portable AC myself. I also love my caliper, and a 3D scanner has really changed my reverse engineering game as well. Keep up the great work, thanks for the comment.
Tnx. Can you do "4X basic{9.0}"? I hope someone from the developers community of FreeCAD or Ondsel will recognise the need to make the GD&T tolerancing easier: I think we should not need to give it separately. And converting the bubble to feature is a hassle if you need to give lots of them.
Nice tutorial but I can not create the datums plans... I tried many times doing a simple square with the sketch. my points are in line together. I selected the same exact plan all along the video to see if I had make mistakes. but my datum plan doesn't move from the origine when I select my point... any idea? thanks
it's the use of dead-english romantic-prose "heighth" that really drags it down, coming in close second is the out of touch and forced laughter at things that have zero humor. otherwise a pretty good intro to the tooling, even if the narration has a tendency to grind the ears. but as they say "i'm an engineer, not an english major."
Excellent! Thank you. Is there a way to reference a previously, automatically-defined constraint (e.g.: Constraint12) in the definition of a second constraint. (without defining a "spreadsheet")? I'm looking for something like: "=Constraints.Constraint12 + 2mm". Blessings.
Thanks. I have not found a way to do that, but there might be something in the freecad expressions documentation that makes it possible wiki.freecad.org/Expressions
Exceptionally good tutorial video. Nobody covers it all, but the author here covers as close to everything as anyone else- and you will not need much more than this to enable you to become PROFICIENT with FreeCAD in short order. FreeCAD is very quirky/strange, even downright annoying at times. I am a 56 year old man who has done my share of 2D work in Autocad as well as high end 3D simulation work- but that was all in the past. I have a current and serious need to do some real CAD work, and I did not think it would take me too long to get up and running on another CAD package, but I was wrong. After many days of reviewing the CAD options out there, I decided FreeCAD was the best option for me- mostly for all it can do, but also for the confidentiality of what I am working on. Any program that needs a connection to the Internet is NOT an option. Many of you have heard that FreeCAD has a steep learning curve compared to other packages out there, and those comments are TRUE. Take the time you need and carefully soak in this whole Tutorial, and it will end up being about the fastest way to get you "over the knee" relative to learning what you need to learn. Thanks for a job well done.
Great question. In that case, it would be the order in which you click the lines. It's not very significant though, since I didn't yet tell SolidWorks how long I wanted either line to be. Once I put a distance on the lines, they'll be fixed at the proper length.
I checked the result of the surface created by this tool in the ziess inspection software. There was about 6 mm difference in accuracy between actual stl file and the the surface created by this tool. Is there any tool in freecad which could generate accurate surface on stl file?
This was incredibly useful. I'm just curious though, why did you keep standing on the body? And why don't you use a shovel to hide the body? Seems like it'd be quicker than using a space bar.
