To change the height of the star, we will have to double click on the Pad object and the extrusion parameters dialog will open again, with the corresponding height. If we want to move the star or rotate it, we will have to do that operation on the sketch. This sketch can be edited by dragging the points to a new place and the star in three dimensions will change. If we now want to edit the object, we will only have to double click on the sketch so that the drawing appears on the screen, with all the points that we have put at the beginning. If we switch to perspective view, we can see our star in three dimensions. and extruding to create parts (Should know), will show how 2D drawings can be. In the extrusion parameters we choose the dimension or height that we want for the part, in this case 15 millimeters. Freecad uses the concept of a body (Blue icon) as a single part/solid or a. To get a piece in three dimensions we are going to extrude our sketch by selecting the corresponding icon. Our drawing will look in plan view as in the following figure. Once we are done, click on the Tasks tab and click on the Close button. īy clicking on the points, we can drag them with the mouse to better refine the dimensions of our drawing. Now we will create a star with the polyline icon. If I use the Part > Extrude, the points along the circle do not appear as lines on the object. Consider the lines in the edges of a cube, but now with a perfectly round cross section without corners. Next we are going to draw a simple object, a star.įirst we adjust the editing controls in the Tasks tab, so that the drawing will fit on the grid. Then I would like to extrude the sketch to a solid object with superficial axial lines corresponding the points. Īnd we choose the XY plane as the base plane to place the new sketch.Ī grid will appear on the screen where you can draw in two dimensions. Open the FreeCAD application and click on the icon to create a new document. First we will create two dimensional objects (sketch) with the Part Design workbench and then we will extrude that drawing to create the final three dimensional object. This paradigm is called constructive geometry.įrom now on we will use a different method. Select New Sketch in toolbar and select XY plane as sketch plane on the dialog. These objects can later be joined, subtracted or intersected. Create new document and switch workbench to Part Design workbench. Until now we have worked with the Part workbench which is used to directly create 3D objects.
