I am going to show you how you can add editable textfields to your custom TechDraw symbols. I will use the surface roughness symbol that I have already created as a starting point. Enabling editable fields for FreeCAD TechDraw in the SVG To generally enable editable fields you first need to add a freecad namespace […]

Trying to place a projection of A2Plus components directly on a page I am trying to place a view of an A2Plus shaft assembly on a TechDraw page. First I tried placing projections or views of A2Plus components on the drawing page directly. This would create an empty views for some of the components. The […]
Finding and downloading CAD models of standard components When you want to use standard components in your assemblies, you do not need and you also shouldn`t model them up on your own. Manufacturers of standard components provide 3D CAD models of their produced components in most industry standard 3D formats. The most flexible 3D format […]
Designing a functional shaft on paper In order to demonstrate the application of the newly created surface roughness and edge annotation symbols, I created this real-life project of a functional shaft used in a transmission machine. As the first step I created a hand drawn sketch of hte shaft to define all the requirements. The […]
Downloading the edge annotation symbols To use edge annotation symbols in your technical drawing download the symbols from the github repo FreeCAD-TechDraw-Symbols After you have downloaded the symbols, the will come in a zipped folder. You need to unzip them and store them so you can find them later. Annotating a specific corner or edge […]
Finding surface annotation for technical drawings in literature A lot of manufacturing drawings of mechanical parts need to include definitions about the surface quality of the produced part. Surface annotations tell the manufacturer of the part, how it should be produced and what the surface finish should be. When creating techniucal drawing in FreeCADs TechDraw […]
This is the result of the first day of the 30 day 30 minutes challenge. Because I often needed surface roughness annotation in TechDraw drawing in FreeCAD I now finally created one for myself. I have also uploaded it to Github for you to try. Downloading the surface roughness annotation from Github Download the surface […]

Announcing my 30 day FreeCAD challenge
30 minutes for 30 days challenge Together with a friend we will be doing a fun challenge between ourselves throughout April (1.4. – 30.4) starting next week on friday. We want to get better at the things we are interested in and just have fun. I decided to mainly do FreeCAD related projects. Goal The […]
Machining flat sheets on the EMCO F1 CNC I was machining flat sheets out of plastic when I noticed something. With time the cutter got progressively deeper into the workpiece. I thought this was strange. I checked the workpiece, the work coordinate system and more but it would just not make any sense to me. […]
My friend and myself agreed to also meet this summer, after last summer has been a great experience for us both. We learned a lot while using the emco and doing more and more complex parts programming everything by hand. In winter before we would meet, we thought about what we would produce on our […]
