This polygon is a 2D shape that we have to extrude in order to get a solid. We use a polygon with the correct size for a M8 nut: A radius of 14.38 mm divided by With this very crowded button we can add all kind of shapes. We want to take it one step further and add a M8 nut so that we can secure the benchdog from below the table. We combine these parts by selecting both of them and then use a Boolean union operation.Ī super simple version of the benchdog could be done here. We increase the value of the z placement to 17.

We can then move the part with one of the arrows.Ī more precise way is to move a part in the placement section of the panel on the left. To move a part in FreeCAD we right click on the part and select transform.

This cylinder is 27 mm in diameter and the height of 10 mm is already correct. We can see the new cylinder from below or by hiding the first one with space. We add another cylinder for the upper part. The height of the cylinder should be 27 mm. As the input field expects a radius we type 19.85 divided by two and FreeCAD does the math for us. The diameter of the cylinder should be 19.85 mm. In the lower left corner we have a window that shows all the Data related to the selected object. The part that goes into to hole is a cylinder.Īfter adding the cylinder we have to change its size. We want to model a benchdog that can be used with a MFT table or any other table with 20 mm holes. For hiding a part select it and press space. We delete a part by either selecting it in the main window or in the model tree on the left hand side and then pressing the delete key. The part workbench is used to add simple shapes such as cubes, cones or a torus. In this tutorial we want to focus on the part workbench. They are covering specific aspects of the 3d modeling workflow.

Think of these as the ribbons in Microsoft office. A very important concept of FreeCAD are workbenches. We are working with FreeCAD version 0.19 in this tutorial. We have an overview article on what‘s possible in woodworking when using FreeCAD. In order to create something useful we will create a very simple Benchdog that you can 3d print and use for your workbench. It is not one of our normal build articles but focused on using FreeCAD step by step. This tutorial it the first of a multipart series on how to use FreeCAD in woodworking. In the first part of this tutorial we use the part workbench to create 3d printed benchdogs. Today we use the FreeCAD in a woodworking project.
