addesigns Posted February 17, 2012 Posted February 17, 2012 Anyone know of any good LISP routines that would be beneficial to someone doing plumbing iso drawings. Maybe turning a 2d into a 3d? Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 I guess Im just seeing what is out there. Seeing if there is anything that will help with doing ISO plumbing drawings and using already existing 2D to create these ISO's so they dont need to be started from scratch. So far we have used orbit to give the drawing some depth and have gone from there, but I wanted to see if there was some better way to do this. Quote
ReMark Posted February 17, 2012 Posted February 17, 2012 Back up the bus. You've done 2D isometrics and are using the Orbit command to give them depth? I'm not sure if 1) that's a good idea or 2) why you just don't draw your piping arrangement in 3D to begin with. Can you post a sample drawing so we can have a look at just what we are talking about? It does not have to be a complete drawing. Just enough so we have a good idea of what you are currently doing. Thanks. BTW...I've done a handful of one line piping schematics in 3D and the beauty of it is one can look at the piping from different angles and really see what is going on. A 2D isometric is just too restrictive in my opinion. Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 This is not really a good example but it will hopefully give you an idea of what I am talking about and how our plumbing guy does it. He uses orbit to try and get a 30 60 degree angle and starts drawing his ups and downs. The drawing doesnt actually have any plumbing attributes to it. I just had to make one up quick with a background example.dwg Quote
ReMark Posted February 17, 2012 Posted February 17, 2012 OK...I guess I thought you'd give us something with a little more detail in it. My suggestion: stop what you are doing immediately. Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 I will be sure to tell him that. Its like trying to teach an old dog new tricks around here. Some things and practices I would change, but Im not in charge. Guess I will just have to implement my way of doing drawings for my own work (when I start selling my house plans). Thanks for the help anyways Quote
ReMark Posted February 17, 2012 Posted February 17, 2012 Sorry. I got interrupted by a phone call so I never got to finish. What does your CAD guy have in the way of experience working in 3D? Do you have a library of symbols that you are working with? Not isometric symbols either. They don't need to be isometric if you are doing this in 3D. Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 Here is a better example. Im not sure why he doesnt draw in 3D. Prolly not used to it. We have a library of symbols that are in 2D. I created a bunch of pull-down menus for them. M2.1 Plumbing ISO Plan.dwg Quote
ReMark Posted February 17, 2012 Posted February 17, 2012 I could post a representative sample of a 3D single line (schematic) piping drawing if you like that I did. Re: The M2.1 iso. It's flat. Everything is at elevation "0". 3Dorbit doesn't do you much good. Don't get me wrong. Your 2D iso is fine but it is not the same as a 3D piping schematic especially when it comes to looking at the piping from different angles. Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 That would be great, maybe I can try and convince him to change his ways. I know that if it were me, I would be doing it in 3D Quote
BlackBox Posted February 17, 2012 Posted February 17, 2012 Out of curiosity, why not use Civil 3D, or AutoCAD MEP? Quote
ReMark Posted February 17, 2012 Posted February 17, 2012 The attached schematic was saved in AutoCAD 2004 file format. Once you have opened it invoke the 3DORBIT command and use it to move the drawing around. You'll notice immediately that you can view the piping from any angle and that it was done in all three planes (X, Y and Z). Sample3DpipingSchematic.dwg Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 Yes. that looks much better. I have to agree that the way he does it isnt bad either, but practice in 3D is only gonna benefit him in la futura. Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 Renderman, plumbing guy uses 2010 MEP. I use AutocAD2010. I only really do the electrical drawings Quote
ReMark Posted February 17, 2012 Posted February 17, 2012 Yes. that looks much better. I have to agree that the way he does it isnt bad either, but practice in 3D is only gonna benefit him in la future. No it isn't bad but then again it isn't truly 3D. You have to decide if 3D is of any value to you or not. Quote
BlackBox Posted February 17, 2012 Posted February 17, 2012 Renderman, plumbing guy uses 2010 MEP. I use AutocAD2010. I only really do the electrical drawings AutoCAD MechanicalElectrical & Plumbing...? I also asked, as I may be granted my request to transfer to another group (internally) which does Mechanical, Electrical, and (Plumbing?) Utility work (i.e., Water, Sewer, Force Main, etc.), and they currently do not use AMEP either. That is solely due to their currently using Land Desktop though, and I'm facilitating their transition to Civil 3D now... Always been curious as to why they aren't using AMEP, or at least working to do so. Thought I'd get others' opinion? (I should probably start a thread for this... Sorry.) Quote
addesigns Posted February 17, 2012 Author Posted February 17, 2012 Yeah, Im confused as to why we do not all use MEP since, we are a MEP Consulting Firm. Oh well, I guess I will use what they have. Quote
CM Hew Posted February 29, 2012 Posted February 29, 2012 Please follow the thread started by me entitled "Sweep Object in 3D lines and Curves without twist" in AutoLISP, Visual Lisp, DCL section. I have a lisp called Pipe3d.lsp which could be helpfull to convert 3d Line to Pipe line, which might be helpfull in your case. I taken your drawing for a trial. Have a look Sample3DpipingSchematic Pipe3D.dwg Quote
