We will insert equivalent of a REVOLUTION function This is where you can approach tree function :Įach modifier is an equivalent of a function in any mechanical CAD modeling OR G to move and then Press SHIFT Y for example to forbid movement along Y axis (same for X, Z).OR Press G to move points then X, Y or Z to force the movement in one of these direction.Always draw facing the sketch using : 1(face), 3(side) or 7(top) or 9(opposite of the actual view)).
Blender 3d tutorial how to#
How to avoid having points away from my sketch plane ? Just type A (for all) G (for move) and move your Vertices to the good position then left click mouse button. Lets say we want to move my Vertices (2) to (3) In our example if I type 3 (side view) I will see everypoints from side viewĪctivate the magnetic snap to absolute grid (1) How to move all points to a perticuliar plane ? Type Y so you can scale every vertices that went wrong along the Y axes and put them back on a XZ planeĮxample :I went completly wrong with this drawing, 2 points are no longer in the XZ plane If you want to quickly put back every point, lets say on th xz plane (wich is a front view) : That is a big problem but you can easely correct and avoid this. Step 3: ISSUE, It is hard to stay on a planeįrom time to time you will at first have difficulties drawing on a same sketch plane, if you move vertices around not facing the sketch, vertices move in all x,y,z direction and the drawing is no more aligned.Goto to the treeview structure and rename the "plane" in Screw Body for example Leave the edit mode and go back to Object mode (using TAB) I am discovering this add on and this is not a tutorial how to use it (Note that these cotation are not controlling the drawing) Select the vertices again and add as much point you wantĪdd some cotation with the Addon tool (optional for fun and check) Select vertices and then type G to move them as they snap to the grid you can easely start to draw the general size of the srewĬlick on the EDGE SELECT so you can select an edge There are a lot of ways we could have begun this tutorial, this is one of them, now we are going to move, add, vertices so we can approach the shape of the screw Then clic on the magnet and make sure it is lighted Put the magnetic grid on by selecting SNAP TO INCREMENT and ABSOLUTE and MOVE Now we see that each little square is 1 milimeterĬlic on the VERTEX SELECT button to only select vertex If your loose the front view juste type 1 again Zoom in (Mouse wheel), use SHIFT + center wheel button clicked to scroll keeping in front (well, as every new application you will have to get use to navigation)
S 0.01 clic on scene to validate the scalling operation (or press enter) (dont forget to select all if deselected : A ) Since our plane is 2000x2000 mm we will scale this plane to 0,01 You will notice that the indication of the unit is precious for usġ0 centimeters means the smaller grid size you can see is 10 cm.Īs we want to design a 5 cm screw we will have to resize this plane (the points that define the plane will than move alltogether to smaller coordinates, once again we are not modifying the global scale of the object, this is important) Now type 1 to get a face view of the scene (with no perspective) We did not rotate the object 90°, we rotated the plane that makes this object 90°, if you check the coordinate of the object it is still x 0 y 0 z 0 and that is good ! In blender dont mix up the coordinate of the vertices and the coordinate of the object Type R X 90 (rotate along x axis 90°) and click anywhere in the scene to confirm We are going to rotate this plane so it is face to us (in th ZX plane) When you enter the edit mode you are in, the mesh of the object, this is where you can change shape of each vertice of the object. Select your plane, press TAB or use the menu EDIT MODE Yes, it will not be as quite easy as solidwork or others, but the aim is to be more precise with blender. It is a near way of approaching technical design. This tutorial will design a precise screw. Blender 3D may seem for non-user quite difficult to approach, and yet there are a lot of ways to use it accuratly with measures and tree function structure.
