therealsaint01 Posted January 17, 2011 Posted January 17, 2011 Hi I am trying to construct a sort of bath/hot tub, i just dont know if i must loft, revolve or sweep(the red line) because none of them work and i don't know how to break it up either..and then to build a circular wall around it, sure i can figure that. please Thanks bath problem.dwg Quote
ReMark Posted January 17, 2011 Posted January 17, 2011 You're drawing consists of three layers: 0, 3D Trimming and Dimensions the colors of which are, respectively, white, 30 (orange), and 9 (grey). Your geometry is a bit weird. You have two cyan lines and the red profile (a polyline) of the tub on layer 0. Everything else is on the layer called 3D Trimming. This includes a large elliptically shaped spline, a blue elliptically shaped spline, two orange lines and an orange semi-elliptical shape that is identified as a region, and a small yellow ellipse. Most of the entities are at one of two elevations: 0.00 or 500.00 with the exception of the red profile. Honestly, what were you attempting to do with all these entities? I can hazard a guess with respect to the profile and maybe the small yellow ellipse but the remainder of it just makes no sense. Were you going to create an inner and outer solid and subtract one from the other to arrive at your "tub"? Please explain the function of each element in your drawing so we have a better idea of what you had in mind. By the way, it is NOT good practice to override layer colors. With everything you have going on here just using two layers (0 and 3D Trimming) is not a good idea either. And it is way too early for you to be thinking about dimensions when you can't even create the tub you want. Quote
ReMark Posted January 17, 2011 Posted January 17, 2011 I was able to loft your profile using the path option and picking the small yellow ellipse as the path. Is that what one thing you were attempting to do? Quote
JD Mather Posted January 17, 2011 Posted January 17, 2011 Is something like this what you are after? (dwg was too big to attach here even after zipping) Quote
ReMark Posted January 17, 2011 Posted January 17, 2011 JDM: Did you use Inventor? What method did you use? I used a loft between two copies of the profile and as my path I used one half of the small yellow ellipse at elevation 0. Then I mirrored it. Quote
JD Mather Posted January 17, 2011 Posted January 17, 2011 JDM: Did you use Inventor? What method did you use? Yes, Sweep with path and guide curve in a real 3D modeler. Quote
ReMark Posted January 17, 2011 Posted January 17, 2011 Owwwwwwwwwwwwwwwwwwwwwwwwwwwww! That hurt. Thanks. Quote
Bobzy20 Posted January 18, 2011 Posted January 18, 2011 ReMark, how did you create the tub using the Loft command? Step by step would be great. Cheers Bob Quote
ReMark Posted January 18, 2011 Posted January 18, 2011 See post #5. The explanation is pretty simple. The result... Quote
Bobzy20 Posted January 18, 2011 Posted January 18, 2011 Unfortunately I need more help if possible. Quote
ReMark Posted January 18, 2011 Posted January 18, 2011 Unfortunately I need more help if possible. Say it ain't so Bob. Ok. I've attached a dwg for your use. I am leaving it up to you to create the actual solid. BTW it was saved in 2000 file format so there should be no problem with it. Bath tub Bob.dwg Quote
Bobzy20 Posted January 18, 2011 Posted January 18, 2011 I used the Loft command to Loft between the 2 profiles and then selected the Path option and selected the one half of the small yellow ellipse and I get this error.Modeling Operation Error:The guide curve does not intersect all profiles.The selected entities are not valid.

ReMark Posted January 18, 2011 Posted January 18, 2011 I've done this now three times with no problem. I have provided a nearly completed drawing and you are still having a problem? I used AutoCAD 2010 and I see you are using 2011. There shouldn't be any problem with the Loft command what-so-ever. At the moment I can't think of a reason why it won't work for you but will work for me. OIE? This is what you should be able to produce given what I have provided in the dwg file. Quote
SEANT Posted January 18, 2011 Posted January 18, 2011 I can get ReMark’s file to work, but it doesn’t quite match up with the OP’s construction geometry. Here’s is my attempt based on OP geometry. All Profiles and Guides recreated as splines. Lofted vertical, horizontal as guides. Surface sectioned for upload. The surfacing features in AutoCAD do seem quite demanding; requiring a specific balance between sufficient information (for control), but reduced to the absolute minimum for efficient downstream computation.

ReMark Posted January 18, 2011 Posted January 18, 2011 OK. I used the profile the OP provided. What does not match up? The rim? Maybe I used the wrong path? Quote
SEANT Posted January 18, 2011 Posted January 18, 2011 The top rim, yes. It's thinnest point is wider than the OPs top rim. Quote
ReMark Posted January 18, 2011 Posted January 18, 2011 The top rim, yes. It's thinnest point is wider than the OPs top rim. Alright. Well that gives me something to think on then. Thanks. Quote
Jack_O'neill Posted January 18, 2011 Posted January 18, 2011 y'all do realize that none of these tubs will hold water. Ain't got no bottom. Quote
ReMark Posted January 18, 2011 Posted January 18, 2011 As soon as you sit in it Jack it will have plenty enough bottom. We hadn't gotten to the bottom of it yet! Like this thread, it's bottomed out. Quote
Jack_O'neill Posted January 18, 2011 Posted January 18, 2011 As soon as you sit in it Jack it will have plenty enough bottom. Just couldn't resist. It better have plenty of bottom before I get in, or it may turn into an express elevator to the basement! Quote
