How to model an easy part for CNC machining in FreeCAD - Product Design - Flowwie & sliptonic

[@tenlittleindians]

It looks like you drew it in the correct orientation but I watched the path creation video and this model opened in the wrong orientation. Is this a bug in freecad?

[@FreeCADAcademy]

No, actually that was my mistake, because the version that I sent to sliptonic was slightly different from the 'demonstration' version, which I created for the video. In the version that I sent to sliptonic, I used the XZ-plane for my basic sketch. Very good question -thank you!

[@chrisalbertson5838]

In general, we like to design parts in the orientation that they will be used. This way the parts fit into assemblies. But almost certainly most parts need to be re-orientated for manufacturing. And you might even need a different orientation based on if it is to be 3D printed or made on a milling machine.

[@pieyed1302]

Awesome explanation of design changes. Welcome back!!

[@CrazyMineCuber]

Nice to see what is important to think about when designing. Both for manufacturing but also for simplifying future design changes.

[@angeloc700]

You’re like a Freecad Jedi. Very cool and thanks for sharing!

[@DomTranquille]

When defining your radius, make sure 'Auto remove redundency' is ticked under the 'Solver messages' tab in the Task Tab

[@lewiscobb7817]

Hey Flowie - nice to see you back. I just watched both your and Brad' s video and while I don't use path workbench yet, it was a good overview of the process. Also, I liked the instruction about dealing with the topo issue as it relates to sketches referencing other sketches. Thanks !

[@FreeCADAcademy]

Hey Lewis, glad to hear from you again! I hope you're doing well. I'm not using Path WB either at the moment but hopefully in the future - it was a very fun project!

[@PikachuG5]

"The larger slot holes do something incredibly stupid." That made me LOL.

[@wiseoldfool]

Extremely helpful, I'm not feeling so overwhelmed by FreeCAD now.

[@Kit_an_Code]

Excellent Excellent teaching method and introduction to parametric constraints. Currently new to this CAD software (and modeling in general) - Quite helpful demonstration overall. Easy to follow and understand.

[@Zachthesloth]

Well done Flowwie! I love your work!

[@FreeCADAcademy]

Thanks, I'm glad to hear you like my work!

[@cheesecakes121]

this program and this series is wildly helpful, thank you for making it

[@abdullahking7530]

when I do the radius constrain thing to a cirkel it says : datum 30,00 mm for the constraint with index 13 is invalid.

[@GlassonDesignStudio]

The two videos were very enlightening. Thank you

[@whoopi5257]

Loved this tutorial! Is there anyway you can make a tutorial to show how to build a simple frame that uses the 50/50 core system?

[@FreeCADAcademy]

Yes but probably I would use a different cad software for that kind of more sophisticated project

[@MrVdiff]

your tutorial was very carefully executed. The sliptonic video seemed to go too fast for me. 10 stars

[@TechieSewing]

Thank you, worked for me! I followed the video in the new 0.20 weekly development release and it was almost the same, I didn't get warnings when I applied the same constraint to more than one object though, it just worked. Also I noticed that if I left my initial shapes in the Sketcher not visibly parallel or otherwise lined, I had to make more constraints manually than in the video. And twice, in this and another video, by setting vertical length between two objects FreeCAD decided to put an object A above B while it was intended the other way round. Couldn't find the reason for that behaviour.

[@PavelLaminar]

Hi there, Flowwie. Thanks for video, but can you explain, please why didn't use a mirror tool for slots?

[@thaipeople8958]

I could not go further regardless many times create new document and got the following error ++++ 13:23:31 Traceback (most recent call last): File "", line 1, in : Datum 30.00 mm for the constraint with index 13 is invalid 13:23:31 App.getDocument('Unnamed').getObject('Sketch').setDatum(13,App.Units.Quantity('30.000000 mm')) ++++++ the issue is must tick the box Auto remove redundency in the Task Tab

[@thaipeople8958]

Dear Sir 1) Thanks for teaching bigginers here. 2) Improvement suggestions. 2.1 the Cursor need to be Larger and Colour is perhaps in Red. 2.2 You need to move cursor Slower if you do have to stick with your current mouse setting. Thanks again my teacher.

[@riceball4u172]

Great vide9! How do you rotate and move the item around at 11:49?

[@andrearagao7910]

Thanks a lot, just started learning CAD and it really helped me.

[@dnmnsmith]

Excellent, thank you. The kind of tutorial free ad needs!

[@FreeCADAcademy]

Thank you very much, Duncan!

[@FunderWindsurf]

Devo Sunglasses! So... no linking new sketch to face, nor to any external 3d geometry, nor to external 2d curves (and I assume lines and points also cannot be used?). Fixing this topo-name problem will greatly increase the power of FreeCAD. Thanks again for these great demonstrations.

[@Hopeinformer]

Strangely I don't get the same error as you did at 19:14 but instead the new sketch is only visible in Sketch_Edit mode and the original sketch shows after closing it. There is an error that says "Failed to validate broken face, internal name: Pad"

[@FreeCADAcademy]

You might have destroyed the first sketch. Maybe you have some overlapping lines or a contour that is not closed. That are the most common errors.

[@Hopeinformer]

@@FreeCADAcademy thank you for you help. I'll look into those things

[@palasko83]

i have folow step by step and my sketch 001 is there but when i try to create pocket i get input error "Linked shape object is empty"

[@FreeCADAcademy]

I'm sorry to hear you are having problems. I'll check this issue.

[@jackjrgensen5356]

i get the same error and the sketch001 is not visible i part design window even when i use the spacebar.

[@raybuck9675]

@@FreeCADAcademy I have followed the tutorial step by step 5 different times. There must be a step missing in the video because I always get the "Linked shape object is empty".

[@olas2012]

I'm following the the video exactly. Mine wont "Glue" to the X and Y center lines without me dragging it there and I keep getting an error about constraints when trying to define the first arc as 30mm. It wont let me do it and I dont know what I'm doing wrong or different

[@SzaboB33]

I found this video: kzbin.info/www/bejne/fJK5fYmda5qaopo Basically what I did in this case is turn on "auto remove redundants" and "auto update" in the "solver message" little window, I deleted the arc and started to draw it again. Then it work but I am not sure what it removed I just started with the SW too :D

[@kombeezy833]

Edit** I see he has "Auto remove redundants" checked on the solver. I get the exact same thing. Looks like there is a cut in the video because the shape moves positions but you don't see the action to move it....not sure what I'm doing wrong.

[@wlotek18]

I can't go further than creating second sketch with the bigger holes which is created since 9:00, after closing the sketch bigger holes are not visible and pocket command is not working... watched and go through couple of times again but step by step but it do not comes out. Help

[@haydenmacdonald1938]

Mine is doing the same thing, and I don’t know what to do.

[@haydenmacdonald1938]

I’ve now figured it out! Before, when you are connecting the smaller holes in it, you press the construction mode button to connect the 116mm length of the small holes. This makes everything construction lines and blue rather than the green. Deselect this and try again. It should work!

[@raybuck9675]

@@haydenmacdonald1938 Hayden, Thanks! That was the step the somehow was missing in the FreeCad Academy video. Glad you found the solution. I am now able to create the pocke.

[@juperrr]

Hi there, thanks for the video. I have created a path profile operation and I have a problem. The profile is basicly a circle, but when I read the g-code there is this "K" coordinate, I think it is Z offset. The thing is LinuxCNC doesn't like that "K". It can't run the program with it. I removed it manually from the code and it works perfectly. The question is: Is there a setting in FreeCAD so that this "K" doesn't appear in the G-Code? Thanks a lot !

[@Monks_made]

Do you have an email that we could contact to get answers to more specific applications?

[@davidmac2134]

How do you save the model to gcode for milling? I haven't been able to do that in freead

[@SP74723553]

First of all thanks for your great video.. but I have some challenges with the Sketch001 - it simply do not appear in the model and I have tried several times according to your instructions on this part and also made a very simple model where the problem is the same .. could you advise me - what am I doing wrong / not doing - using 0.20 29177 (Git)

[@donstelfox2936]

Nice, very informative, thank you.

[@FreeCADAcademy]

Thank you very much, Don!

[@krausternet]

I was hoping that 0.2 had fixed the topo naming problem. I tried this lesson using 0.2 and it still has the topo naming problem. After removing the arc and redrawing it as three tangent arcs the model rebuilds with the same problems. That is disappointing.

[@jasonsmith1806]

When i tried this, sketch 001 just wasnt there, invisible

LOL now you have almost 4x the subscribers you had when you made this - how awesome is that?!?!

Could you Please make a video on how to design a job with double side? I just can not find anything about it? for example how do you create a coin with double side in freecad. I try but after a couple of scatches it is getting more and more difficult not to get so many erro's :( I do hope that you consider it. Sry my english
