Ubrigens Posted January 7, 2016 Share Posted January 7, 2016 Trying to extrude a closed polyline to create solid. Getting message stating cannot extrude self intersecting curve!!!!! What is it and how do I locate and eradicate it. Thank you Quote Link to comment Share on other sites More sharing options...
Cad64 Posted January 7, 2016 Share Posted January 7, 2016 A self intersecting curve error means that your polyline is crossing over itself. You will need to zoom in close and inspect your polyline to find where the lines are intersecting. Quote Link to comment Share on other sites More sharing options...
Ubrigens Posted January 8, 2016 Author Share Posted January 8, 2016 Thank you.Tried and failed to find overlap by zooming.Is there a more technical way of locating the fault???? Tried breaking the polyline into it's component parts and can easily create an edge surface model! Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 8, 2016 Share Posted January 8, 2016 Stop. Please attach a copy of the drawing to your next post. Someone here will take a look at it. Quote Link to comment Share on other sites More sharing options...

ReMark Posted January 8, 2016 Share Posted January 8, 2016 (edited) A PDF is no good. We need an actual .DWG file to view and test. Try again. Well? We haven't got all day. Either you want our help with this or you don't. Which is it? Edited January 8, 2016 by ReMark Quote Link to comment Share on other sites More sharing options...
Cad64 Posted January 8, 2016 Share Posted January 8, 2016 If you can't find any intersecting geometry, maybe the problem is overlapping lines. Try running the OVERKILL command. A few other things you can try: BPOLY command will create a new closed polyline when you click inside your current polyline shape. You should then be able to delete the old geometry and extrude the new clean polyline shape. PRESSPULL command is another way to Extrude and does not require a closed polyline. I would Explode the Polyline and then run Presspull. If none of these suggestions solve the problem, attach your drawing file for us to check.

Ubrigens Posted January 8, 2016 Author Share Posted January 8, 2016 Thank you to both for your help. Using BPOLY worked,not tried Presspull yet,just hoping my luck holds. I am not sure on the procedure for attaching a DWG part drawing to this type of document---but appreciate the offer! Thanks a lot! Quote Link to comment Share on other sites More sharing options...

Ubrigens Posted January 11, 2016 Author Share Posted January 11, 2016 (edited) Thank you so much for your previous assistance---can I trouble you again????? Created my solids using BPOLY and extrude,but now I am unable to rotate as the rotate gizmo has vanished;when 3Drotate is selected I seem to access 2D rotate only :have read most of the threads on gizmo,and tried numerous unsuccessful options Any suggestions ,please Edited January 11, 2016 by Ubrigens Idiocy Quote Link to comment Share on other sites More sharing options...
Cad64 Posted January 11, 2016 Share Posted January 11, 2016 What is your SHADEMODE setting? If you're in 2DWireframe, try switching to a 3D visual style, such as Realistic and see if the gizmo returns. https://knowledge.autodesk.com/support/autocad/getting-started/caas/CloudHelp/cloudhelp/2016/ENU/AutoCAD-Core/files/GUID-7BD066C9-31BA-4D47-8064-2F9CF268FA15-htm.html Quote Link to comment Share on other sites More sharing options...
Ubrigens Posted January 11, 2016 Author Share Posted January 11, 2016 No luck I'm afraid---tried all the visual alternatives and still get only an apparent 2D rotation!!!!! Never had this problem before---are we sure it's not associated with BPOLY command???? I'm in 3D modelling workspace. Quote Link to comment Share on other sites More sharing options...
Cad64 Posted January 11, 2016 Share Posted January 11, 2016 I am 100% positive it has nothing to do with the BPOLY command. The ability to see the gizmo has nothing to do with any commands you use to create geometry. In fact, you can even use the 3DRotate command on 2D linework. Check your GTAUTO system variable and make sure it is set to 1. Also, I have to ask, you're not trying to use the 3DRotate command while viewing the model from a front, top or side view are you? You're viewing your model from a perspective viewpoint but the gizmo is not appearing, correct? Quote Link to comment Share on other sites More sharing options...
Ubrigens Posted January 11, 2016 Author Share Posted January 11, 2016 GTAUTO set to 1---confirmed. I am trying to work in a perspective view created using 3D orbit. Out of interest-- what's the problem with Orthographic views??? Quote Link to comment Share on other sites More sharing options...
Cad64 Posted January 11, 2016 Share Posted January 11, 2016 You will have to ask the Autodesk programmers about the orthographic views. I don't have a definitive answer for that. And as for your problem with the gizmo, I'm out of ideas. I don't know why it's not displaying. The only thing I can suggest is to WBLOCK your model out to a new drawing and see if the gizmo comes back. Maybe there is an error in your drawing file that is causing this problem. Or upload your drawing file here so we can take a look. Quote Link to comment Share on other sites More sharing options...
Ubrigens Posted January 12, 2016 Author Share Posted January 12, 2016 Thank you for all your help--sorry we can't reach a conclusion. Did try recreating the model but no change. Whilst idling around I did find that in 3D modelling and the SE isometric view with realistic visual style,that if I selected a solid,the MOVE gizmo appeared and selecting that gizmo then put me into the Subobject tab,thus allowing me to access the rotate gizmo!!!!!! All this without selecting 3D rotate---shall probably take up knitting. Quote Link to comment Share on other sites More sharing options...
