help needed with pump body // Work in Progress

I have been asked to create a 3d exploded view of a simple pump for a new website I am writing. I can cope with most of the modelling with my limited 3d experience, but I need help with a couple of features. I attach a 2d portion of the pump body, with the features highlighted.
Basically, I need to know how to create the radiused radial recess (note this is not a full rad) and how to create a screw thread on the end of the body.
Any help would be appreciated.

Nice. Having those 2D drawings will make it really easy. You can texture them on a plane to use as a guide in the orthographic views.


See my image planes tutorial here:

http://forums1.caligari.com/truespace/showthread.php?t=1474

It uses the old tools and needs to be updated, but should still be helpful.


As far as creating the shape goes, I'd start with a cylinder and add loops where you're gonna need to add the details like the dips and ledges. Then you can individually scale the loops uniformly to bring them inward to add the detail. Once you have the basic shape down you can create "cutter" objects and boolean out the holes you need.


If you need more visual examples let me know! :)


-Jack.

Hi Jack,

Thanks for that. Your planes tute is very informative. I still don't know, however, how to create a realistic external screw thread. The 2d drawing just shows the standard representation of a thread.
Any ideas?

Hmm... there are a couple of ways.


The most usual method that I've seen for doing that would require using the Lathe tool on model side to create the the threads from a profile shape.


The tedious way would be to use the add edges tool to cut out 3 parallel paths for the screw thread then select and scale outward the middle one. ;-)


Neither is really the kind of modeling I usually do since I'm a low poly guy. LOL

There still should be a tutorial in the manual showing how to create a screw. Think that could be used as basics for any form of screw you want to create.


If you create a screw and cut it's shape (use boolean) out of a solid you have the counterpart needed.

Hi Jack,

Thanks for that. I will have a go using your suggestions, unless someone else knows a different way?

Hi Emma,

Thank you. I shall make sure I read the manual properly!

If you've got a tight deadline and your still having trouble, you may want to consider this course by daybe:

http://www.caligari.com/products/trueSpace/ts5/Courses/IntroProductIllustration.asp?Cate=Training&Subcate=Fundamental


The course is done in 7.11 and mainly uses the old 6.6 tools but it's very well done and covers the whole process from concept thru modeling, UV, texturing, lighting, and the final render.


Also I think Emma's right about there being a screw example in the manual.


BTW, don't forget to post your progress. ;)

Hi camelot,


I'm not sure if this is exactly what you're looking for but, I wrote this threading tutorial a couple of years ago. It uses 6.6 but the technique should still work on model side of newer versions.

Hi Dele,

That's exactly what I want. Excellent tutorial. Thank you very much!

Jack,

Thanks again. Haven't really got a deadline - the website's almost finished and this exercise is for the maintenance manual for the pump, which the client says can follow later on.
I will make sure I post my progress though.

That is a great tutorial Délé! Did the thread part in modeler, brought over to Workspace and did the PEing and SDSing. Used glass shader to shade, render to file using built in DX9 renderer and here is what I got. Ahmmm I think I ended up with left handed threads though :o. Very cool in any case :) .


Those who want to use glass shader for non transparent objects for like shinny metals or bumpmap rough metals:


Set transparency to 1 in shader panel

Set Scene "transparency mode" found in stack view settings to no hidden faces. This can also be done per object using object render attributes.

For rough looking objects use a normal map

Noko,

Very nice! I have used Dele's tute to create the screw thread I needed except that I used a triangular base instead of the rectangular, so that the thread appears differently to the ACME type thread that Dele illustrates. Will post a WIP soon.

Thanks! Can't wait to see what you came up with. Ahhhh, I have to get back to mechanical stuff. I am dying to make some machines in tS7.5 :jumpy:.

This is my first attempt at one half of the pump body.

looks pretty good.you might want to use smooth instead of auto-facit on the sides.

Looks really cool! Sometimes when using booleans you may end up with shading problems in Workspace and Modeler for that matter. Not sure if you are running up with that here.

Thanks for your input, noko & kena,

having been a 2D designer with General Motors for most of my working life, I am struggling with 3D. Any comments you make are GREATLY appreciated.
For my particular application though, I feel that my results should be good enough for my customer.
Once again, thank you.
This is a great community.

Turned out great! Nice work camelot. I'll have to try your triangle method. :)

Yes it did turned out good, triangle threads look right on, great job there!

Fantastic! :banana:

Thanks for showing us, hope to see more work from you. I need to really get back into mechanical devices with tS.

You sure that's not a lightsaber? :-)

That's the first thing it made me think of too! Wouldn't take much converting... the first lightsaber props were made out of all sorts of weird bits of junk anyway (including camera fash parts, windscreen wipers and the like!) - a pump component wouldn't be so far off....


Very nice shiny render you came out with - looks great. :D

Thank you noko, Jack, wickedwitchoftheweb and nez for your comments.

noko, here's the latest exploded pump assembly. Almost finished!
Note that I mistakenly gave the body a chrome type finish - it's manufactured from bronze - in my first render.

Artistically I like the contrast between the bronze and the chrome. You should enter this in the gallery competition. :)

Hi Jack,

Thank you. I am pleased that you think it's good enough to be entered into a competition as this is my first attempt at anything mechanical.

lol, same here, I deal with machinery all the time and rarely are they shinny even though we do everything imaginable to make them so. Seeing this pump makes me think, "see, it can be done!". Please enter into Caliagari contest, it looks really really good.
