![]() It should now look just like the image below. Select the lower right point (vertex) of the horizontal line Origin and then the center point of the grid and apply the coincident constraint to fix your shape.Īt this point you should have a fully constrained sketch as indicated by it changing color and the message shown in the Combo View.Select the top horizontal line and apply the horizontal distance constraint and give it a value of 5 mm.Select either the horizontal or vertical line and apply either a corresponding horizontal distance constraint or vertical distance constraint and give it a value of 26 mm.Select the bottom horizontal line and the right vertical line and apply and equal constraint.Select the start and end points of your polyline and click on the coincident constraint to close the polyline.Select the vertical line on the right and then click on the vertical constraint.Select the two horizontal lines with your mouse by clicking on them, and once selected, click on the horizontal constraint.(The redundant constraint is shown in the Task view, click on the blue reference and press delete.) NOTE: Since this tutorial was written there have been improvements to the sketcher solver, if it detects a redundant constraint it will turn the sketch orange in colour, and before further constraints are added, the redundant constraint should be removed. To avoid leaving edit mode when pressing Esc too often, change the Esc can leave sketch edit mode preference ( introduced in version 0.19), see Sketcher Preferences. Don't press ESC a third time or you will exit edit mode if this happens, click on the Model tab, then double-click the Sketch element in the tree, or right-click and select Edit sketch in the context menu. But first make sure that you have exited the Polyline tool by right-clicking or pressing ESC twice the mouse cursor should turn back from a cross-hair to the standard arrow cursor. If you had Auto constraints on, some of these constraints will have been applied automatically, if not, do the following. Once you have the basic shape, we will start applying the constraints. It does not need to be perfect as the final shape is done with constraints. Next you will want to use the Polyline tool and make a shape roughly like that in the next image. Once you click OK, FreeCAD automatically switches to the Sketcher workbench and opens the sketch in edit mode: Place your mouse pointer over the border when the pointer changes to a two-way arrow, press and hold the left mouse button and drag. You can make it wider by dragging its right border. Note: it's possible that the OK button may not be visible if the side panel is not wide enough. In the Tasks tab from the Combo view, select YZ_Plane in the list and press OK:.We will attach it to a plane from the Body´s Origin. We need to define where the sketch will be attached.This will create the sketch within the just created body. When creating a sketch, if no existing Body is found, a new one will be automatically created and activated. Click on Create new body to create and activate a new Body Container.Then we will build the solid inside the body by starting with a sketch. ![]() It is a good habit to save your work often, so before anything else save the new document, giving it any name you might like.Īll work in Part Design begins with a Body. Once there, you will want to create a new document if you have not done so already. This Tutorial will not use every feature and tool available within the Part Design Workbench, but should use enough to give the user of this tutorial a basic foundation upon which to build their knowledge and skills.įirst begin by making sure you are in the Part Design Workbench. These features will either add material to, or remove material from the solid by use of additional sketches and accompanying feature operations. You will start by creating a core shape from a base Sketch and then build on that shape, adding what is known as Features. ![]() All of the necessary dimensions to complete this task are given. In this tutorial, you will be using the Part Design Workbench to create a 3D solid model of the part shown in the Drawing below. (each section has its own split Video below) This tutorial will take user through the steps needed to model the part shown in the image below using sketches.Ī video of the whole construction is here: This tutorial is not a complete and comprehensive guide to the Part Design Workbench and many of the tools and capabilities are not covered. This tutorial introduces the new user to some of the tools and techniques used in the PartDesign Workbench. Mark Stephen ( Quick61) and HarryGeier ( HarryGeier)
