![]() Projections are defined as the visual representation of an object on a specific plane, it displays the properties of the object that are visible from that specific orientation. This object will contain everything related to the Drawing. We now have a folder called Page in the Tree View. Slect the dropdown menu next to New A3 landscape drawing.Templates are the base for the creation of Drawings, you can use the templates provided or create your own. Select the elements that you wish to add and drag them into the group.You can alter the name of the group by double clicking on it from the Tree View. In the Tree View, right-click on the name of the document.To reduce the time required for this tutorial, it is compulsory to group together similar elements in the Tree View to apply operations at the same time to several elements. The reader has finished the Draft tutorial.The reader has the basic knowledge to use the Part and PartDesign Workbenches.So before exporting, select the items you want, without the elipsoids.This tutorial is meant to introduce the reader to the basic workflow of the Drawing Workbench, as well as most of the tools that are available to create blueprints. You will see that the method has created some wild elipsoids that you should take care not to export to have a nice rendering. It is possible to make a Path Array along a circle to make a circular weld. To weld around cylinders, simply select the circle at the base of the cylinder when applying the Path Array function. You can overlay primitives as below to get a weld layer look. Select PathArray object then press Ctrl + C / Ctrl + V, To avoid having to repeat the same operation several times you can copy and paste the previously created weld seams.Ĥ.1. Do the same as before except that you select the line instead of the edge. If you want the weld to stop before the end of the edge you can do the same with a line.ġ.4. Configure PathArray and Ellispoid objects to achieve the desired graphic appearance. NB : Primitivemust be in the same direction as the edge,Ģ.9. Right clik -> Transform : to bring it closer from the weld area and press OK, Choose an elipsoid with default parameters,Ģ.4. The result is weld seams as shown below, it's quite a time consuming job for large assemblies.Ģ.3. Secondly, it is reproduced along a path.Principle is to insert a succession of primitives along the weld seams : The goal will be to place primitives representing welds in order to obtain a result as close as possible to reality. There is no function to automatically add welds in FreeCAD. ![]() The version with welding is used for the rendering : The version without welding is used for the drawing: That's why I make several versions of the same file with a version without welding. It is not advisable to leave the welds on a 2D drawing as this overloads the whole thing for no good reason. As close as possible to the real object, shown below. ![]() Here is a screenshot of the part choose, it's a nacelle for Piggot wind turbines (part that holds generator and hub of propeller).įunctionally there is no interest, it is only visual to be able to represent the welds in a realistic way. I'm going to use a part that I have modeled before but you can use one of your own parts. Step 1: Principle of adding 3D welding graphicsįirst, we need a part on which to do our welding. ![]() We will mainly use Part and Draft workbenches and functions Primitives, Epsiloid and Path Array. Principle is described in Step 1 and then other steps describe practical cases. For that we will use epsiloidal primitive sequences placed on the weld seams. This tutorial explain how to model welds with FreeCAD, version 0.19. ![]()
