Serial No. 195
Application of ‘Loft’ tool Ex.1-Autodesk Inventor 2013 (with caption and audio narration)
In this exercise, we are using a partially constructed assembly of ‘Grating for Gas Oven’. We will add some 2D sketches, work planes and a loft feature to proceed towards its completion.

Transcription of Video
- Open the ‘Grating for Gas Oven’ (.iam) file.
- Here a pre constructed ‘Part1’ is visible in this Assembly.
- Activate the ‘Create Component’ tool to create a new part in the Assembly.
- Select the XY Plane of the assembly as a base plane for the new component.
- Create a new sketch on the XY Plane of the ‘Part2’.
- Take the project of Part1 by using ‘Project Cut Edges’ tool.
- Select the projected model edges in the graphics window and convert them into construction geometry.
- On the Ribbon, click 'Finish Sketch' icon.
- Now we will create a new work plane, parallel to YZ Plane of Part2 with the aid of ‘Offset from Plane’ tool.
- Activate the ‘Offset from Plane’ tool from the Work Features panel of 3D Model tab.
- Select YZ Plane of ‘Part 2’ from the Browser Bar.
- Mini toolbar appears in the graphics window.
- Drag the manipulator arrow button in the graphics window.
- Enter the offset distance value (-1.875) inch.
- Click OK to create a new work plane.
- Create a new sketch on this work plane.
- Take the project of bottom edge of the Part1 and Y Axis of Part2.
- Convert both the projected edges into construction geometry.
- Draw a rectangle of value 0.25 inch X 0.349 inch with the help of ‘Three Point Center Rectangle’ tool.
- Apply a dimension of 0.2991 inch between center point of rectangle and projected edge of Part1.
- Finish the 2D Sketch.
- Create a new work plane parallel to Work Plane1 at an offset distance of 3.25 inch.
- Close the visibility of Work Plane1.
- Create a new sketch on Work Plane2.
- Take the project of top line of previously drawn rectangle.
- Close the visibility of Sketch1 and Sketch2 from the Browser Bar to clear the screen.
- Take the project of Y Axis of Part2.
- Create a new line of 0.4040 inch with the aid of Offset tool.
- Apply a Coincident Constraint between midpoint of newly created line and projected Y Axis line.
- Apply 0.59860 inch dimension between these lines.
- Add two more lines to close the profile.
- Finish the 2D Sketch.
- Open the visibility of Sketch2 from the Browser Bar.
- Activate the ‘Loft’ tool from Create panel of 3D Model tab.
- Loft dialogue box is visible in the graphics window.
- On the ‘Curves’ tab, specify the sections to loft.
- Click under the ‘Sections’ heading and the select both the sketch profiles in the graphics window.
- Click OK to execute the Loft feature.
- Close the visibility of Sketch2 and Work Plane2 from the Browser Bar.
- Change the colour of model to Steel.
- Return back to the Assembly environment.
