This will be difficult to explain, but I have a model of a whale tail, and if looking at the front view, it is just a block without any differences in thickness. I would like the tail end to be more tapered and thin, but do not know how I can do this since I created the object by extruding up from the XZ plane. As I said, I'm pretty knew to the program so if you could try to be slightly basic with your answers I would appreciate it. I have included the file.</P> Thu, 27 Feb 2020 23:21:56 GMT https://forums.autodesk.com/t5/inventor-forum/how-to-extrude-not-uniformly-tapering-thinning-out-an-extrusion/m-p/9347114#M152153 greene.anna.lee 2020-02-27T23:21:56Z https://forums.autodesk.com/t5/inventor-forum/how-to-extrude-not-uniformly-tapering-thinning-out-an-extrusion/m-p/9347187#M152154 <P>I think you want to use multiple workplanes, constructed by angle and then the split command to get what you desire.&nbsp; <A href="https://knowledge.autodesk.com/community/screencast/b37d315b-e2d1-4018-a9bb-eafe509b2329" target="_blank" rel="noopener nofollow noopener noreferrer">See Screencast</A>.</P><DIV class="iframe-container" style="position: relative; height: 0; margin: 0; padding-bottom: 101.5625%;"><IFRAME width="640" height="650" style="position: absolute; left: 0; top: 0; width: 100%; height: 100%;" src="https://screencast.autodesk.com/Embed/Timeline/b37d315b-e2d1-4018-a9bb-eafe509b2329" frameborder="0" allowfullscreen="true" webkitallowfullscreen="true" scrolling="no"></IFRAME></DIV> Fri, 28 Feb 2020 00:27:11 GMT https://forums.autodesk.com/t5/inventor-forum/how-to-extrude-not-uniformly-tapering-thinning-out-an-extrusion/m-p/9347187#M152154 jhackney1972 2020-02-28T00:27:11Z https://forums.autodesk.com/t5/inventor-forum/how-to-extrude-not-uniformly-tapering-thinning-out-an-extrusion/m-p/9347208#M152155 <P>Hi! In addition to John's solution, you can use Face Draft to pull the faces inward. Please take a look.</P> <P>Many thanks!<BR /><BR /></P> <P>&nbsp;</P> <P>&nbsp;</P> Fri, 28 Feb 2020 00:42:28 GMT https://forums.autodesk.com/t5/inventor-forum/how-to-extrude-not-uniformly-tapering-thinning-out-an-extrusion/m-p/9347208#M152155 johnsonshiue 2020-02-28T00:42:28Z
