![]() ![]() This is done by selecting the constraint in the tree view and pressing Space. If not, have a look at section Troubleshooting.Ĭonstraints can be disabled by changing its visibility. With the button Solve you can check beforehand if this new constraint can be solved by A2plus. When creating a constraint such a dialog will be displayed after you pressed a constraint toolbar button:Ībove: The A2plus Constraint Properties Dialogįor certain constraints it allows you to modify the constraint direction. As workaround you can use the toolbar button to restore the transparency settings. However sometimes the transparency setting for parts is lost when reopening the assembly due to a bug in FreeCAD. Every part can be made transparent using the normal FreeCAD editing.To toggle the transparency view of the whole assembly you can use the toolbar button.Alternatively you can hide a certain part by selecting it in the model tree and pressing Space to toggle its visibility. To show only certain parts in the assembly, select these parts in the model tree and use the toolbar button.To go back to the normal view, left-click into the assembly. This will make the whole assembly transparent and highlight the two objects that are connected via the constraint. To show a constraint select it in the model tree and use the toolbar button.If the moved part already has constraints it will be placed accordingly by pressing the toolbar button because this triggers to resolve all constraints of the assembly. When you placed the part where you like it, left-click with the mouse. To move a part around in the assembly, select it in the model tree and use the toolbar button.A2plus therefore offers these tools to move and view parts: The more parts you add, the more important it is to keep track. Therefore also have a look at section Troubleshooting for strategies to resolve such cases. The constraint will be added in the model tree attached to the affected parts.įor complex constraints between parts A2plus might fail to solve the constraints. A dialog will pop up that is descried in section Constraints. Then click the toolbar button of the desired constraint. To create a constraint between parts, keep the Ctrl key pressed and select each an edge or face of two parts. After a constraint A2plus will move the parts according to the constraint if possible. Toggling the toolbar button sets the way you can select several several edges, faces etc.: Either with a single click or by Ctrl+click.Īssembling parts is done by adding constraints between parts. To save the assembly and close it afterwards, the toolbar button can be used. This can be achieved with the toolbar button that converts the selected part to a static copy of the original part. For well-defined parts like screws it is however useful that their shape cannot be edited. Imported parts will keep their external dependencies and can be edited. If you select one or some parts in FreeCAD's the tree view, A2plus will ask you to only update the selected parts. The toolbar button imports parts too but recursively over possible subassemblies. To update changed parts in assemblies click on the toolbar button. This will open the part into a new tab in FreeCAD or switch to its tab if the file is already opened. To edit a part from the assembly, select it in the model tree and use the toolbar button. Parts that are already in the assembly can be cloned with the toolbar button. (You can change this later via the part property Data fixed Position.) The first added part gets a fixed position by default. This way one can for example only import a sketch to assemble further parts using the sketch to determine the part positions. ![]() When using the button you can choose what part from a file should be imported as part. The button adds all bodies in the selected file as a single part. Now parts can be added to the assembly by using the toolbar button or. It is recommended (but not necessary) to save it in the same folder of the parts you want to assemble. To create an assembly create a new file in FreeCAD. The A2plus code is hosted and developed on GitHub and can also be installed manually by copying it into FreeCAD's Mod directory.Īt first switch to the A2plus toolbar in FreeCAD. Therefore you should update it regularly using also the menu Tools → Addon Manager. It can easily be installed via the FreeCAD Addon Manager from the Tools → Addon Manager menu.Ī2plus is under active development and will get new features frequently. The A2plus workbench is an addon to FreeCAD. ![]() This documentation describes A2plus version 0.4.56 or newer. The A2plus workbench is an external workbench to assemble different parts in FreeCAD. ![]()
