atemnot Posted January 16, 2012 Share Posted January 16, 2012 I'm trying to make a curved wall with different heights, but i can't manage to do the loft of the object. I keep getting "The selected entities are not valid." I tried remaking all the little polylines but nothing seems to work.. Please help. loft problems.dwg Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 16, 2012 Share Posted January 16, 2012 How did you create your curved lines? Quote Link to comment Share on other sites More sharing options...
atemnot Posted January 16, 2012 Author Share Posted January 16, 2012 from top view according to some dimensions i had. 2circles (r12+r9 ) that i trimed where they interset.. Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 16, 2012 Share Posted January 16, 2012 Sorry, I find that difficult to believe. If your centerline paths were real arcs, segments of a circle or polylines that were curve fitted then the profiles would definitely loft.

ReMark Posted January 16, 2012 Share Posted January 16, 2012 Created using polylines that were curve fitted. Quote Link to comment Share on other sites More sharing options...
atemnot Posted January 16, 2012 Author Share Posted January 16, 2012 so i should remake the path for the loft? i exploded it and rejoined it and still doesn't work.. Quote Link to comment Share on other sites More sharing options...
atemnot Posted January 16, 2012 Author Share Posted January 16, 2012 i don`t understand. i started the path from scratch and after i select all the polylines and i chose the path i get that error again.. "The selected entities are not valid." Quote Link to comment Share on other sites More sharing options...
atemnot Posted January 16, 2012 Author Share Posted January 16, 2012 can you please send me the file modified? i really can't manage to make that loft and i don't see where i make it wrong... i remade the path several times and doesn't work thanks..

atemnot Posted January 16, 2012 Author Share Posted January 16, 2012 yes. i restarted everything and i didn't use circle+trim this time, but arcs and still no result.. same error i attached the new file, maybe you can tell me where i do wrong yet another try.dwg Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 16, 2012 Share Posted January 16, 2012 Ah....a class assignment. What I did was very simple. I erased the two guidelines on either side of your centerline and divided the centerline path into sections based on the location of your wall profiles. I drew circles on those segments and connected the centers with a polyline. I used the Pedit command, selected the polyline I just drew, then did a curve fit. I lofted two profiles for each section. Then I assembled all of the sections and unioned them. I had a total of five sections. The last two were just straight lines. Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 16, 2012 Share Posted January 16, 2012 The five separate sections I created. Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 16, 2012 Share Posted January 16, 2012 This is the sequence I followed. On the left side you see the circles I used (radius = 2) and the yellow polyline before curve fit. On the right is the polyline after using Pedit and the "Fit" option. I used the LOFT command, selected the two profiles at either end of the segment and the polyline curve was my path. Simple. Now it is your turn. I have some sheet rock work to do this morning so I have to go. Good luck. Quote Link to comment Share on other sites More sharing options...
atemnot Posted January 16, 2012 Author Share Posted January 16, 2012 finally.. after hours of trying. i'm so happy i managed to make it. i tried how you said with circles but i got the same error. (maybe because i didn't use fit curved because i didn't find that option so i used spline curve..) but then i tried by simply breaking the points of my centerline where i had the red-section polylines, duplicated them and made loft of each segment and it worked. oh god im so happy! million thanks for your help Quote Link to comment Share on other sites More sharing options...
ReMark Posted January 16, 2012 Share Posted January 16, 2012 You're welcomed. One of the options for the PEDIT command is called FIT (as in "fit" a curve). I do believe I mentioned it in post #13. Why, indeed, I did! Congrats on solving your problem. Quote Link to comment Share on other sites More sharing options...
atemnot Posted January 17, 2012 Author Share Posted January 17, 2012 sorry for bothering again.. but i need some help what is the best and easiest method to make a solid or a surface between a curved polyline and a solid "wall"? thanks in advance Quote Link to comment Share on other sites More sharing options...
