This is especially important where two or more fillets meet or intersect on the model. One reason that it is the best method is it allows you to decide the order of filleting. The first method is the BEST method and should be used whenever possible. The first method is to create the solid model using extrude or revolution just as you have being doing to this point in the course and then insert the fillets on the solid model.The second method is drawing the fillets in the 2D sketch and they will be created when the sketch is extruded or revolved. USER TIP: Inventor allows two methods of inserting fillets and chamfers. To complete the model, change the colour to: Chrome – Polished Black. Set the Select mode to Loop and select the edge as shown in the figure. (Figure Step 11A and 11B) Figure Step 11A Figure Step 11B Step 12Įnter the FILLET command and in the Fillet dialogue box, set the Radius to 0.0875. Ensure that you set the correct radius for each fillet.

Insert the fillets as shown on the figures. Using what you just learned, insert the 1 inch radius fillets. (Figure Step 9A and 9B) Figure Step 9A Figure Step 9B Step 10 On it, draw and dimension the slot and extrude it. It is called a round when material is removed from the object. Technically, a fillet is when material is added to the object. It can be tangent to two lines, a line and an arc, or two arcs but it must be tangent at both ends. A fillet is simply an arc that is tangent at both ends. The point where they touch is called the point of tangency. A line tangent to a circle passes the circle and touches it on only one point on the circle. Solid Model Geometry Lesson Tangency – Part 1Ī point of tangency is the theoretical point where a line joins an arc or where two arcs join each other making a smooth transition. It is always better to insert the fillets as features since that makes them much easier to edit after the solid model is created. In the Inventor Advanced book, drawing fillets on the 2D sketch will be taught.

In this module, inserting the fillets after the solid model is created will be taught. There are two basic methods of inserting fillets in Inventor. Most CAD systems, including Inventor, use the term fillet for both. Technically, it is a fillet when material is added to the object model and a roundis when material is removed from the object. It can be tangent to two lines, a line and an arc, or two arcs. A fillet is simply an arc which is tangent at both ends.
