Inventor Tutorial 7 : Glider Design (2D laser cutting)
By the end of this exercise you will be able to convert an autodesk design into a file suitable for cutting on the laser cutter
Wing Raiser (This will be made out of 2mm balsa wood) Use 2D sketching tools to construct wing raiser as shown Use Trim tool to create wing outline Create 3D wing raiser by extruding to 2mm thick Save part as Wingraiser
Wing Design (This will be made out of 2mm balsa wood) Use 2D sketching tools to construct wing shape as shown Use Trim tool to create wing outline Create 3D wing by extruding to 2mm thick Save part as Wings
John Lee @ SHU 2006 2
Rear wings (This will be made out of 0.5mm card) Use 2D sketching tools to construct rear wing shape as shown Use Trim tool to create rearwing outline Create 3D rearwing by extruding to 0.5 mm thick Save part as rearwing
Rear stabiliser (This will be made out of 0.5mm card) Use 2D sketching tools to construct rear stabiliser shape – note that is exactly half of the rearwing shape Use Trim tool to create rearstabiliser outline Create 3D rearstabiliser by extruding to 0.5 mm thick Save part as rearstabiliser
You are now ready to convert these autodesk part designs into files that the laser cutter can deal with. You will do this by converting them to .dxf files using the inventor drawing interface This tutorial will now show you what to do to create two pairs of the wings
John Lee @ SHU 2006 3
Re-open your wing part design and go to File > New > and open a Standard .idw drawing page By default it will have a border and title block – go to the LH panel and delete these to leave an empty sheet
Now RH click on the Sheet 1 and choose Edit Sheet
Change the Size to Custom Size and enter a height of 102mm and a width of 308mm – this is the standard size for the balsa wood billet
In the Drawing Views panel – choose Base View and in the Open dialogue box, browse to find your Wing.ipt file
John Lee @ SHU 2006 4
Carefully position the drawing on your sheet and then repeat this process to bring in a second set of wings
Go to File > Save Copy As and choose the .DXF file type. This is the file that you will take down to the laser cutter.
