LenseOnLife Posted November 4, 2015 Share Posted November 4, 2015 Hi, I'm back - and starting at the very beginning. Decided to start with cylinder type models, but the results are not consistent. The problem is with the top surface using planar decals. Looking at the attached photo you can see 2 poor quality decals and I can't work out what I'm doing wrong and 2 that are OK For each, I started with the right hand outline, did the flip/copy/attach and then used the lathe. The breadboard (bottom left) probably had the most complex shape and yet turned out really nice. The only other one which turned out OK is the middle one which was a basic cylinder - nothing complex at all. No doubt I'm making a really basic mistake in the process but I can't work out what I'm doing wrong.. Anyone got any ideas on what I'm doing wrong - or how to work out where the problem is? Thanks for any assistance, Oliver Quote Link to comment Share on other sites More sharing options...
Fuchur Posted November 4, 2015 Share Posted November 4, 2015 In general it looks like you have internal patches / 2 patches above eachother there... Could you show a wireframe? Just for testing, you could click on one point on the "poor"-looking patch and drag it away. If you see another one below it, there is the problem.

Hash Fellow robcat2075 Posted November 4, 2015 Hash Fellow Share Posted November 4, 2015 If you could post one of the bad ones with the decal for it someone could look at it. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted November 5, 2015 Hash Fellow Share Posted November 5, 2015 Another possibility causing the bad result is doing a lathe when the "center" CP is either exactly on the center axis or crossing past it. The center CPs of the lathe shape should be just a hair short of reaching the center axis. Quote Link to comment Share on other sites More sharing options...
Admin Rodney Posted November 5, 2015 Admin Share Posted November 5, 2015 This doesn't specifically address your problem, which others have answered well but because you are using A:M we have an alternative means to decal in situations like this. Specifically, anything that can be lathed can easily usually be lathed with 5 cross sections which allows us to close the ends with 5 point patches. Here are two examples, coin and character spinner. In the latter case the decals are placed on two 5 point patches (click on image or click here to see it spin/animate). The underlying point being that there are several ways to create a patch that can be decaled. Quote Link to comment Share on other sites More sharing options...

I clicked on one of the CPs and there was another one below - in fact there is what looks like another copy below. Before going any further - I'm heading back to basics and try to work out why I have these copies - thanks for the heads up, great to have something to mull over instead of belting holes in the wall with my head.

LenseOnLife Posted November 5, 2015 Author Share Posted November 5, 2015 Still having difficulty One suggestion was to set the left hand CPs slightly off-centre - which I did, and then did the Copy / flip /Attach I then did the lathe action It looks fine, but then I just checked a couple of CPs by grabbing and moving them and I still have extra faces superimposed on each other. I also saved the object after each procedure which I'm also uploading in case someone can see what I'm doing wrong. Object1AfterCopyFlipAttach.mdl Object1AfterLathe.mdl Object1AfterMoving2SuperimposedCPs.mdl The question now is - how do I stop these extra faces being created when I do the lathe operation Thanks all for your suggestions - maybe I'm not understanding them and/or implementing the suggestions Cheers and thanks for your help, Oliver Quote Link to comment Share on other sites More sharing options...
NancyGormezano Posted November 6, 2015 Share Posted November 6, 2015 I believe you can just use the lathe tool - no need to cfa first - that is what is causing the problem. Here's a simple example screen capture Note that I peaked the splines before I hit the lathe selected only one cp (any cp) - then hit the lathe tool then I closed the top, bottom holes. Now you can decal the top and bottom with planar decal, and the cylinder part with a cylindrically applied decal lathe.mp4 Quote Link to comment Share on other sites More sharing options...

It will get swept 360° around the axis to make the other side when you lathe it. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted November 6, 2015 Hash Fellow Share Posted November 6, 2015 Go to the tutorials link in my signature and look at the "Modeling" section. There are several tutorials that may be useful to you, especially the first two. Quote Link to comment Share on other sites More sharing options...
