<p>Edit 01/2020 :<br>Added a different version designed to be protected by epoxy resin. See the make for a preview.</p><p>This is a round badge for replace the one one the side body of a BMW F800R 2010.<br>This represent the coat of arms of germany. Basically<strong>it’s not a nazi thing</strong> but the design used between 1928 and 1935 before the change made by nazi.</p><p>It was inspired by a BMW patch here : <a href="http://f1-wrc.com/images/patches/Motorrad-eagle-patches-5pcs-werke.JPG">http://f1-wrc.com/images/patches/Motorrad-eagle-patches-5pcs-werke.JPG</a></p><p>The .svg origin is from Wikipedia : <a href="https://en.wikipedia.org/wiki/Coat\_of\_arms\_of\_Germany">https://en.wikipedia.org/wiki/Coat\_of\_arms\_of\_Germany</a></p><p>&nbsp;</p><h3>How I Designed This</h3><p><strong>Step 1 : Base disc</strong></p><p>&nbsp;</p><p>I have used Fusion 360.</p><ul><li>&nbsp;Trace a 60 mm circle on a sketch.</li></ul><p>&nbsp;</p><ul><li>Extrude it to 2mm.</li><li>Made a sketch on the top of your body and trace another circle at 5 milimeter of the first one.</li></ul><p>Extrude the edge circle. Now you have the basic surface of the badge. <strong>Step 2 : Add the bmw helix</strong></p><p>Made another sketch on the top of the previous centered circle.</p><ul><li>On the sketch, trace a cross who represent the BMW helix.</li><li>Ad another circle at 2 mm on the edge.</li><li>Select the top left and the bottom right face and extrude it at 3 milimeters.</li></ul><p>Now you’r supposed to have the centered BMW helix. <strong>Step 3 : Import the svg</strong></p><p>Select the circle face made under the helix. The idea is to import the svg (vectorial image) on this surface.</p><ul><li>Choose import svg</li><li>Choose the dimension and the position on the dialog box.</li><li>Now you have a svg sketch, not perfect but we will work on it. <i>I personaly hide the body of the helix by clicking on the lightbulb on the model navigator. Else I cannot select my sketch well.</i></li></ul><p><strong>Step 4 : Top left and bottom right design</strong></p><p>The svg can be imperfect : Some edge are missing.</p><ul><li>Go on the sketch and delete all the line who aren’t usefull for your design. Just keep the eagle.</li><li>Select all the eagle part on the top right and the bottom right by using ctrl + click on them. Don’t select them all but one by one. If you see an error after clicking on a part that’s because a line is missing on the edge. You have to trace yourself a better line and delete the one who are useless.</li></ul><p>Choose the « cut » option and finalise the extrusion. At this moment you now have the top left and bottom right parts of the eagle who cut the BMW helix. <strong>Step 5 : Top right and bottom left design</strong></p><p>Made the sam that step 3 but with the join option of the extrude dialog box : You need to extrude all the eagle design on theses side. <strong>Step 6 : Finalize the design</strong></p><p>Add some filet on the edge by selecting the circle of the badge and using the key « f » for fillets.</p><ul><li>Draw a sketch an the top circle under the helix with a little rectangle who will « join » the eagle wings. By doing that, you will have a better print by having less retraction.</li></ul><p>&nbsp;</p><p>&nbsp;</p><p>Category: Automotive</p>
