ddustin Posted November 15, 2004 Share Posted November 15, 2004 Here's an air cylinder I'm working on. I'm using boleans for the holes but the hole on the rod end seems to go transparent part way through the stoke. Is that inherent to boleans?

starwarsguy Posted November 16, 2004 Share Posted November 16, 2004 Looks great so far! Keep up the awesome work! I love what you make! Quote Link to comment Share on other sites More sharing options...
Gene Posted November 16, 2004 Share Posted November 16, 2004 Hey Dave, You know, all I had to do was see "Bimba Air Cylinder" and I knew right away who started this post! I am not sure about that one boolean. Are you doing the same thing at the back of the cylinder? That one appears to be ok. Interesting how it's ok in the fully retracted and fully extended position, but elsewhere, it's an anomolie. Nice work. Eugene Quote Link to comment Share on other sites More sharing options...
ddustin Posted November 16, 2004 Author Share Posted November 16, 2004 Gene, Someday I'll do something organic. I don't know why the front bolean goes transparent, I even added another internal cylinder around the rod of the cylinder that was less in diameter than the bolean, but it still shows through. Seems to me there was a post a while ago about the perils of using boleans, and the unpredictable results. Maybe one of the smart guys with offer an explanation. I tried to model the hole in but it didn't work well, the curved surface thing interfered. Realisticlly, I could put flow controls or fittings in the holes (EDIT: done), as they would be there on the equipment. An mov is attached. EDIT: Modified the model to have fittings. Looks better.

Gene Posted November 16, 2004 Share Posted November 16, 2004 Hey Dave, If your like me...I scare myself silly when I try organic modeling. I like what you did with the fittings. Looks good and avoids Booleans. I am curious about a couple of things: Did you use a decal for the threads? If they are going to be seen, adding a bump map using the same decal does wonders! Also, are you using high reflectivity for the body or is it a decal all the way around? Cheers, E Quote Link to comment Share on other sites More sharing options...
John Bigboote Posted November 16, 2004 Share Posted November 16, 2004 That looks good! Should be a big hit with the ladies! Quote Link to comment Share on other sites More sharing options...
gazzamataz Posted November 16, 2004 Share Posted November 16, 2004 Did you use a decal for the threads? That's just what I was gonna ask! Well how did you do it? It's a nice model. I always find AM great for organic modeling but not so good for mechanical fings... (my inability). Quote Link to comment Share on other sites More sharing options...

If they are going to be seen, adding a bump map using the same decal does wonders! Also, are you using high reflectivity for the body or is it a decal all the way around? I created the "illusion" of threads by lathing finely peaked splines (image attached). The only decal is the bimba logo (had to squish the logo to get it to look right). The body is set to 10% reflectivity, some ambiance, and specularity. Gazzamataz, Funny, I say the same things about organic modelling. Wonder if it's a left brain, right brain thing, are possibly previous exposure to mechanical design software like AutoCad etc....

KenH Posted November 16, 2004 Share Posted November 16, 2004 The model looks great. I can see that banging away really quickly as part of another massive machine. You're model is faultless, but I'd like to see you improve the presentation. Although this looks better than your previous projects. Quote Link to comment Share on other sites More sharing options...
Zaryin Posted November 16, 2004 Share Posted November 16, 2004 That looks great. Are you having any trouble with the booleans or are they fairly non-pissing-off ? Quote Link to comment Share on other sites More sharing options...
ddustin Posted November 16, 2004 Author Share Posted November 16, 2004 They seemed innocuous enough at first, but ended up being the wrong choice. I chose to go with the fittings instead, which gave it a more realistic look anyway. May still add air hoses, but that'll have to wait. I'm re-modeling my Fanuc 2000iA/165F robot. Starting over actually. Thanks, David Quote Link to comment Share on other sites More sharing options...
