![]() It, alone, will increase productivity 10X. Streamline Sketching and Feature Based Modeling is easy to learn and implement. It is very important that you look into how you or your engineers are creating the parts. Please go to here to see the other lessons. Now for the fillets and chamfer and we are done. We insert a cylinder locate, size and set it to add. We delete the construction line and exit the sketch and create the extrusion size and set to remove. We create a line between the two midpoints and create a center rectangle and size it. The graphics from the mating parts are available for construction of the sketch. ![]() We exit the sketch and extrude and set to remove. Again we use StreamLined Sketching, no constraints. We will move the new sketch to below the new extrusion. It makes the new extrusion a standalone shape, which means we have to set the sphere to add. So we will move the sketch and extrusion above the sphere. I quickly realize I did not do my design intent. We exit the sketch and extrude to an arbitrary width. Here are the graphics necessary to create the bottom of the handle. We clean up the sketch, leaving a few construction lines. We use what I call StreamLined Sketching. No we will drop a primitive block located, size it and set it to remove, do it again for the bottom. We insert a primitive sphere size and locate it. It automatically goes to the edit part mode, which allows top-down modeling. ![]() We use the “New to Insert” command under the the Control Valve Assembly and name the part Lock Lever. Here is the drawing if you would like to follow along. From what I have seen from these very complicated processes done by the Solidworks Presenters, it is not just limited by the 3D CAD system. There is no right way, just more productive ways. ![]() Of course, there are a multitude of ways to create a model. I always create the part before I watch the Video, so as to not taint my process. I like to show step by step lessons So you can see the commands being used. ![]() But modeling is just one aspect of this well designed productive 3D CAD system. IronCAD is all top down due to the single model environment. While creating 3D models from drawing is the very best way to learn 3D CAD and maybe some design techniques is does not expose the designer to the design flexibility necessary in product design. ![]()
