Can you post the drawing...I need to see what you have done Quote
wdj Posted April 12, 2009 Author Posted April 12, 2009 her are a couple i think show what i mean Quote
CADMASTER1128 Posted April 12, 2009 Posted April 12, 2009 Are you wanting to have the loft line Parallel with the Circle? (Stern) Would it be possible to email the .DWG File to me? Quote
wdj Posted April 12, 2009 Author Posted April 12, 2009 i want the circle to follow the line of the loft instead of being flat this is the dwg file hull.dwg Quote
CADMASTER1128 Posted April 12, 2009 Posted April 12, 2009 i want the circle to follow the line of the loft instead of being flat this is the dwg file I can honestly say, This is the first Time I have been stummped... Quote
wdj Posted April 12, 2009 Author Posted April 12, 2009 i rotated the drawing 5 deg which was estimated then drew a new circle and trimmed then rotated it back, its sloppy but its close Quote
ReMark Posted April 13, 2009 Posted April 13, 2009 Have you considered making the bow using Edgesurf (as there is no Loft command in 2000)? Just a suggestion. Quote
SEANT Posted April 13, 2009 Posted April 13, 2009 Is the interim step of aligning the arcs to the connecting splines required? If so then: Flatten a copy of the splines, offset, snap to two endpoints to create a perpendicular vector, rotate with “Reference” to align circle with perp vector. See attached. hull2.dwg Quote
wdj Posted April 13, 2009 Author Posted April 13, 2009 seant and remark could you give more detail? Quote
shift1313 Posted April 13, 2009 Posted April 13, 2009 there is a post either on this page or the next of another user trying to draw a boat hull. I did several samples screen shots using curves, creating surfaces and using them to slice a solid. Ill try to find it for you. You dont have as many options using 2000. You need 2007 or newer to have loft or sweep commands at your disposal. Quote
shift1313 Posted April 13, 2009 Posted April 13, 2009 found it but forgot i did end up using sweep but i think for what you are asking you will be able to extrude a pline along a path and get what you need. http://www.cadtutor.net/forum/showthread.php?t=33928&page=2 Quote
