The Step by step tutorial to make 3d sketch with AutoDesk Inventor. There are two ways to make 3D sketches. Adaptive and (with the introduction of grounded workpoints in R6) non-Adaptive. We will focus on the adaptive approach. At the end of this tutorial we will discuss the new, grounded workpoint feature in R6. We start our example with a simple assembly. While 3D sweep can be constructed in a standalone part environment, to have adaptability you need to work in the assembly environment. Our assembly consists of two parts. Figure 1 – Assembly At this point we want to create the part that will be our tubing. Select the “Create Component” button from the assembly menu. Name the file, select it’s location and select the template file you want to use. (see Figure 2). Be sure the “Constrain sketch. Create Component Dialogue You must now choose the face to being the sketch. Choose one of the circular extrusions. This will begin a new 2D sketch. In our example the diameter of the hose is the same as the diameter of the connections so we simply project the geometry of the circle. If the diameters are not the same, simply sketch whatever geometry you wish on this face to be used as a sweep profile. (see Figure 3). 2D Sketch on Hose Connection Face. The next step in constructing the tube is the actual sweep. While still in the edit part mode choose the sweep command. In this command you will be asked to choose the profile to be swept (the 2D sketch) and the path to follow (the 3D sketch).

please do show some example of the sketchs so that people that go to this website, have a picture of what its all about. thanks.
