Right-click on the LCS in the model tree: Move it to the corner where we want to attach the leg as follows: This will place our new LCS at the origin: Open the TableTop file, select the Body in the tree and click "Create new co-ordinate system in part." from the Assembly 4 workbench. For this, we need to create Local Co-ordinate Systems (LCS), four on the TableTop and a matching one on the LegFootAssembly. We need to attach it to the corner of the table. This also inserts the assembly by default at the origin: Insert the leg and foot assembly in the same way by choosing LegFootAssembly#Model. This will insert the TableTop part at the origin. Insert the TableTop part into the assemblyįrom the Assembly 4 workbench toolbar, select Insert part into the assembly. As with the foot assembly, a Body is not required. Select the LegFootAssembly tab (at the bottom of the window)įrom the Assembly 4 workbench toolbar, select " Insert part into the assembly".īecause we chose the pad direction for the leg to be up from the origin, and the pad direction for the foot to be down, the parts automatically align correctly, each with its origin at the assembly origin:Īdd a model only. We don't need a Body in the assembly as we did in the Leg and Foot (though it won't do any harm). To enable file model names to appear in the assembly windows, close all the files and re-open them.įor the LegFootAssembly, add a Model. When we attach the top of the foot to the bottom of the leg, we can use the origin without needing to add another Local Co-ordinate System.
This time, when you create the pad feature, make it 10mm, and reverse the direction so that the solid is below the origin: Repeat the procedure again, this time creating a circular sketch with a 60mm diameter:Ĭonstrain the sketch centrepoint to the origin (select both points and hit 'c' for coincident) Our leg model tree should now look like this: This will allow us to use the default Local Co-ordinate System to attach the foot to the centre of the leg later. (Select the two corners, then the origin, and hit the 's' key). Hit ESC or OK and pad the selected sketch by 20mm, then zoom out to see your part:įollow the same procedure as above to create the table leg, with sketch dimensions of 40x40mm and pad height of 300mm.Īs per the table, constrain the corners to the centre with a symmetry constraint. Select "XY_Plane001 (Base Plane)" from the dialog and hit OK.Ĭreate the following sketch of approximately 600mm x 400mm small table top:Ĭonstrain the corners to the centre with a symmetry constraint. This will change you out of the Assembly 4 workbench to the Part Design workbench.Ĭlick on the New Sketch button. Switch to the TableTop tab at the bottom of your window:Ĭhoose the Assembly 4 workbench and create a new Body leaving the default name "Body".Įxpanding our model tree, it now looks like this: Set up the files:Ĭreate the following five files, saving them in the same directory for convenience: We will make a sub-assembly from the leg and the foot, then add four of these to the table top. Our table has just three component types: These file formats are supported on the Sculpteo online platform.Table Assembly Tutorial A very simple subassembly task using the FreeCAD Assembly 4 Workbench It will then be better to export them to a vector format (IGES or STEP-type as mentioned above). They will either generate very large files (over 500MB ), or simply not be exportable by freeCAD below a certain level of precision.įiles with many curved parts / rounded, or large areas based on vector drawings with a large number of points (text, graphics, etc.), will often generate very heavy files in STL. Some files, due to their complexity or nature, won’t be optimal for the export in STL. Note that you must select in the freeCAD tree the objects you want to export.
Freecad allows the import and export in this format, with quite a range of settings. This is indeed the most widely used format, common and used for 3D printing.Īlthough freeCAD does not directly manage the mesh modeling, it is capable to produce mesh for export, making it particularly effective for 3D printing. It is also possible, when you export the file, to convert your modeling in a file defined by a mesh, such as STL. Thus, simply select one of these formats in the drop down menu at the time of saving the file. FreeCAD works on a NURBS system, which allows to record easily your modeling in STEP or IGES format.
