DJAB Posted October 25, 2016 Share Posted October 25, 2016 Guys, I will attach a series of screen shots below. Im trying to create a shape that has a curved / arced end. I create the square part using the spline tool, and extrude. Easy. But when it comes to the arc I must be missing something. I drew the arc, extruded the line as a surface, used the cap tool to create the face I wanted, I thought I would be able to extrude this face as I please, but I can't - its telling me its non planar. I can't see how it could mathematically be non planar using the method that I did... The extrude tool will work, but not the reshape. Also it does not union correctly with the box, the arc seams to have a lot of info attached to it. Any ideas? Andy Link to comment Share on other sites More sharing options...
Des Posted October 26, 2016 Share Posted October 26, 2016 Andy, Try drawing the whole shape in one go and then extruding it. D Link to comment Share on other sites More sharing options...
DJAB Posted October 26, 2016 Author Share Posted October 26, 2016 Des, I was looking for the tool to do this, but I can only see the spline with straight edges, or the spline with curves... Help! Link to comment Share on other sites More sharing options...
R2D2 Posted October 26, 2016 Share Posted October 26, 2016 You could also try the round tool, on an extruded triangle: Link to comment Share on other sites More sharing options...
Des Posted October 26, 2016 Share Posted October 26, 2016 R2D2's way is probably better, quicker and cleaner. The shape tools is the way to go with more complicated shapes. Just select one and click to trace/draw a shape, while still active select another such as a curve tool and it will continue as many times as you wish until it's closes. If you start with a curve instead of vector line, make sure "continuous" is checked in tool options. Don't use the first one on the left (line) if you want it to continue.

bluemonkey Posted October 26, 2016 Share Posted October 26, 2016 Maybe I'm looking at this problem wrong but surely the problem is that you drew just an open arc and not a closed shape. Draw the rectangular 2D shape as you did and extrude. Then draw the 2D straight edge along the base of the arc and switch to the arc tool as Des says until you get the closed symbol. Then extrude. Or draw the outline of the complete shape then extrude. Then on the top face of the extrusion draw a 2d line from one edge of the extruded arc to the next and use the imprint tool to add this line to the top surface. Use reshape tool to push-pull as required. Link to comment Share on other sites More sharing options...
Tech Posted October 26, 2016 Share Posted October 26, 2016 Andy, Looks like you got all kinds of suggestions to get what you want. Do those help? Link to comment Share on other sites More sharing options...
DJAB Posted October 26, 2016 Author Share Posted October 26, 2016 Guys, thanks. Des suggested was what I was looking for, the ability to change from curve to straight lines whilst I define the face, I will have to try that. I was confused however, how did I manage to create a non planar face? I don't understand how that was possible, mathematically? I extruded a line up to the exact same height as the box and caped it to produce a face, how does that make it non planar? Andy Link to comment Share on other sites More sharing options...
Tech Posted October 26, 2016 Share Posted October 26, 2016 The curved smooth arc shape is not flat -- thus it is non-planar as expected. If you are seeing something else, please save, zip, and post the FMZ.zip file so we can comment further. Link to comment Share on other sites More sharing options...
DJAB Posted October 27, 2016 Author Share Posted October 27, 2016 Tech, How is it not flat? I drew it from top view with plane snap on... This is why i'm confused... Link to comment Share on other sites More sharing options...
Tech Posted October 27, 2016 Share Posted October 27, 2016 The extruded shape is not flat in the direction of the arc? We don't see your file posted, so we can't comment further... Please post your file if you need further help. Link to comment Share on other sites More sharing options...
