    You might be interested by FreeCAD because you already have some technical drawing experience, for example with software like AutoCAD. Or you already know something about design, or you prefer to draw things before building them. In any case, FreeCAD features a more traditional workbench, with tools found in most 2D CAD applications: The Draft Workbench.To get more news about 2d drafting, you can visit shine news official website.

    The Draft Workbench, although it adopts ways of working inherited from the traditional 2D CAD world, is not limited at all to the 2D realm. All its tools work in the whole 3D space and many of the Draft tools, for example Draft Move.svg Move or Draft Rotate.svg Rotate, are commonly used all over FreeCAD because they are often more intuitive than changing placement parameters manually.

    Among the tools offered by the Draft Workbench, you will find traditional drawing tools like Draft Line.svg Line, Draft Circle.svg Circle, or Draft Wire.svg Wire (polyline), modification tools like Draft Move.svg Move, Draft Rotate.svg Rotate or Draft Offset.svg Offset, a working plane/grid system that allows you to define precisely in which plane you are working, and a complete snapping system that makes it very easy to draw and position elements precisely in relation to each other.

    To showcase the workflow and possibilities of the Draft Workbench, we will walk through a simple exercise, the result of which will be this little drawing, showing the floor plan of a small house that contains only a kitchen top (A pretty absurd floor plan, but we can do what we want here, can't we?):
    As in all technical drawing applications, it is wise to set up your environment correctly, it will save you a lot of time. Configure the grid and working plane, Text and Dimension settings to your liking in menu Edit → Preferences → Draft. In this exercise, however, we will act as if these settings were left at their default values.
    One option might need your attention, though: the "Fill objects with faces whenever possible" option. If this is marked, closed objects like rectangles or circles will be filled with a face by default, which can make snapping to underlying objects difficult. You can either turn this option off now, or, later on, turn the "Make Face" property of each individual object off, to prevent them from creating a face.
    The Draft Workbench also has two special toolbars: One with visual settings, where you can change the current working plane, turn construction mode on/off, set the line color, face color, line weight and text size to be used for new objects, and another one with snap locations. There, you can turn the grid on/off and set/unset individual Snap locations:
    Turning on all the snap buttons is convenient, but also makes drawing slower, as more calculation needs to be done when you move the mouse cursor. It is often better to keep only the ones you will actually use.
    Let's start by turning construction mode on, which will allow us to draw some guidelines on which we will draw our final geometry.
    If you wish, set the working plane to XY. If you do this, the working plane won't change, no matter the current view. If not, the working plane will adapt automatically to the current view, and you should take care of staying in top view whenever you want to draw on the XY (ground) plane.
    Then, select the Draft Rectangle.svg Rectangle tool and draw a rectangle, starting at point (0,0,0), of 2 meters by 2 meters (leave the Z at zero). Note that most of the Draft commands can be fully performed from the keyboard, without touching the mouse, using their two-letter shortcut. Our first 2x2m rectangle can be done like this: re 0 Enter 0 Enter 0 Enter 2m Enter 2m Enter 0 Enter.
    We can then draw a couple of vertical lines to define where our doors and windows will be placed, using the Draft Line.svg Line tool (note that the "relative" mode box should be unchecked for this step). The crossing of these lines with our two rectangles will give us useful intersections to snap our walls to. Draw the first line from point (15cm, 1m, 0) to point (15cm, 3m, 0).
    Duplicate that line 5 times, using the Draft Move.svg Move tool with Copy mode turned on. Turn also the Relative mode on, which will allow us to define movements in relative distances, which is easier than calculating the exact position of each line. Perform each move operation in sequence on the line that was created immediately prior. Give each new copy any start point, you can leave it at (0,0,0) for example, and the following relative endpoints:

    Traditional 2D drafting is a good way to learn how to draw. It is also a great way to teach yourself about design and art. I have used traditional 2D drafting for years, and it has helped me understand the basics of drawing better than any other method I have tried. Explore this https://srdrrr.tr.gg/Forum/topic-710-1-Japanese-Fashion-NYC.htm site for best services. Traditional 2D drafting is an effective way of learning how to draw because it teaches you everything from basic shapes and shading, all the way up through complex forms and complex shading techniques.
