Hollow out a model is a common task in modeling for 3D printing. The solution to that issue is to use other parts (for example a cube rather than a matrix) The subtraction of one to another makes a weird result, which is not exportable in. Here, it’s called FusionįreeCAD is still under development, some features are still imperfect and Sometimes the Opencascade core on which turns freeCAD has trouble managing certain Boolean operations.įor example, a circular repetition patterns and a box: The new part is called by the operation name. Using the fusion function, the two parts merge into one new part. Then to apply one of the following Boolean operations : For 3D printing application, the Boolean operations between two (or many) shapes will permit you to get one whole part.įor that you just need to select two shapes : To select it, go to the tab part > Boolean operations, otherwise just right click on the concerned part in the arborescence. You can apply Boolean operations among all the created parts. These operations can be used at any time of the modelling, even it’s easier and more logical to use it progressively. It’s appropriate to create a part for each operation, in the aim to be able to make specific modifications on certain parts, with for example the Boolean operations. To modify these geometries you have access to many tools like Boolean operations, fusion, common, cuts operations. The volume modelling is used for simple geometries ( primitive objects like cone, box, cylinder…).
