FreeCAD version 0 21 1, 5 simple 3D models, part 12
Welcome to the channel Miri tech workshop.
My name is Miro in this video there is an accelerated recording of the modeling of five 3D models. During the entire process in FreeCAD, I primarily used Part Design and Sketcher. Some models may have been created using incorrect procedures, but some tips may inspire you. If you have ideas or constructive criticism, please share them in the comments. Have a nice day :)
1.
I used several functions to draw this 3D part, at the beginning I chose where I will model and I chose "Part desig" after creating a new file and sketch I chose "Create polyline" and drew a shape which I then rotated. I changed the line type by repeatedly pressing the letter "M" on the keyboard. After entering the dimensions and closing the sketch, I chose "Revolution" and so I also chose the axis around which I wanted to rotate the sketch. To remove the interior of the model, I clicked on a flat surface and selected "Thickness", entered the thickness and de-clicked the option to remove the material to the interior of the 3D model so that it preserves the outer 3D dimension. I displayed the planes by clicking on "Origin" in the left part of the screen and by pressing the SPACE key I also deactivated the display. In the new working plane I drew "Slot" and in order to see it I chose "View section", entered the dimensions and removed the material with the "Pocket" function. I used the Polar pattern to create several identical holes around the perimeter of the model. At the end I changed the color of the 3D model.

In this video, I solved another 3D part that can resemble a bent sheet metal. At the beginning, I created a simple shape in the shape of "L" in "Part design". I used create polyline and switched the arc parts by repeatedly pressing the "M" key. I entered the necessary dimensions and connections, I closed the sketch and created 3D with the "Pad" function I used the "Pocked" model to remove a new design from 3D and "Mirrored" to mirror our 3D.
3.
Another video is the creation of a 3D model in the shape of a paper clip. I drew a circle in Part design and entered the size of the circle. I drew the drawing and selected a plane that is perpendicular to the plane where the circle is drawn. The plane could also be chosen more easily, for example by clicking on "Create sketch", I marked "Origin" on the left side of the screen and by pressing SPACE I displayed the planes. In the new selected sketch, I drew the shape of the paper clip and defined the dimensions. After closing the sketch, I used "Additive pipe" where in the first part there was the profile I wanted to draw and in the second line I chose the trajectory of drawing the profile. The program indicated the result in yellow, which I confirmed.
4.
This time I modeled a simple 3D model in Part design "Create additive cylinder" on which I entered the required dimensions. Another option was to use "Subtractive sphere" so that I could remove the material in the shape of a hemispherical surface. I set the location and confirmed. When I wanted to create several such operations of the material evenly around the axis, I used the "Polar pattern" function, set parameters such as the number, cut the edge using the "Chamfer" function, and at the end changed the color of the 3D model of the piece
5.
This video is a little longer, but it records the entire process of modeling the pot in the FreeCAD program. I modeled in "Part design" where I chose a new sketch and selected a plane. I drew half of the outer plastic of the future pot. "Create polyline" and then I switched the line type by pressing the letter "M" on the keyboard. I defined the dimensions so that I didn't have any degrees of freedom and so my sketch was colored green. I used the "Revolution" function to rotate the given sketch around an axis. In the new sketch I used "View section" and then I drew the curve: "B - spline by knots" I shaped it into the shape according to the ideas and in the next sketch I drew the shape of the profile that I wanted to draw along the curve. I used "Additive pipe" to create a drawn profile. I used the fillet to round the corners. I removed the inside of the pot by drawing a sketch, which I rotated again but using the "Groove" function. I ended up changing the color.

Vitajte na kanáli Miri tech workshop. Moje meno je Miro v tomto videu je zrychleny zaznam z modelovania piatich 3D modelov. Počas celého procesu vo FreeCAD som primárne využíval Part Design a Sketcher. Niektoré modely mohli byť vytvorené pomocou nesprávnych postupov ale niektore tipy vas mozu inspirovat. Ak máte nápady alebo konštruktívnu kritiku, podeľte sa o ne v komentároch.
Prajem pekny den :)
