Creo parametric6/12/2023 Now, we open the folder or the PTC Windchill work space and select the original sheet part. We select the icon for open folders and select the original sheet part as shown below. This opens the dashboard to define this feature. We then select retrieve data, merge/inherit. To construct this model, we first create a new PTC Creo part. Let’s say, the first model that needs to be developed is the floor panel without processing and with some additional welding preparation. The simple answer is that we use PTC Creo process models with inheritance geometry. So how can we develop a process model for this welding assembly? Should simplified representations or family tables be used? What if the designer responsible for the design and documentation of this process does not have the rights to change the original models? Should the original Creo assembly be restructured? Example 1 – Models with inheritance geometry Finally, the accessories are welded with the plates. Additionally, the stamping and the breakthrough for the centering section and the positions of the cylindrical spacers need to be produced. First, we have to weld the two plates together. Next, we assume that the production of this welding construction will go through a process. The model tree for this welding part is a flat structure in an Creo assembly. Also take a closer look at the Creo model tree in the picture above. Our welding PTC Creo part consists of two plates: an edited Creo part that is welded with the floorboard, and 4 cylindrical spacers which are also spot-welded with the floor plate. We all know that we construct such components as an assembly, but these are later an item, because you can’t take them apart again without flex or saw. To briefly illustrate this for you, we choose a PTC Creo welding assembly. So how can I derive production-appropriate models from a normal assembly in Creo Parametric without having to use the original construction? The answer is the usage of inheritance models. Construction and manufacturing should be clearly separated. Is this effective? Very often I would say no. One way is to design structures during construction that later work better in manufacturing. ![]() ![]() ![]() In design, the question often arises as to how you can design so that you do not have any problems later on, even in production.
