DMclean Posted November 11, 2014 Share Posted November 11, 2014 I boolean added a fairly heavily faceted irregular object to a copy of itself. Now however when I try to boolean it with anything else I get an error Saying Unable to complete the Boolean Operation with ID =8.16 Object doctor reports 165 Colinear segments but that is all. Any idea what is likely causing the problem? Thanks, Doug Link to comment Share on other sites More sharing options...
Tech Posted November 11, 2014 Share Posted November 11, 2014 Hi Doug, Colinear segments are not "problems" per se -- just perhaps redundant geometry that could potentially be reduced. To get you a specific answer, we will need to see the geometry. Can you copy these two objects into a new project and email it to us? Link to comment Share on other sites More sharing options...
DMclean Posted November 11, 2014 Author Share Posted November 11, 2014 Not near the computer today but will send you the geo tomorrow. Thanks. Regarding co-linear segments or points, is there an easy way to get rid of them? When there are only a few I've been able to find them with Object Doctor then "remember" where they are and find and delete one of the lines or points manually, but when there are a lot of them scattered across a complex object that becomes pretty much impossible. While they are not a "problem" on their own I have found they can become rather irksome when I am wanting to manipulate a line or face and suddenly discover that there are extra segments that can cause a face to become non planar, and if the non planariity is very small it can go unnoticed until much later when that actually causes the problem.

Tech Posted November 11, 2014 Share Posted November 11, 2014 Hi Doug, Just use the Fix option for the Object Doctor to remove the unnecessary Co-Linear Segments. Link to comment Share on other sites More sharing options...
DMclean Posted November 11, 2014 Author Share Posted November 11, 2014 That rarely works for me, especially with con-linear segments and or irregular face boundary type errors. In the case of these particular objects, running with the fix option reports nothing (because it didn't fix anything) but then if I run it with add to selection it reports the co-linear segments. Repeating the process yields the same results. Thanks, Doug Link to comment Share on other sites More sharing options...
Tech Posted November 11, 2014 Share Posted November 11, 2014 Hi Doug, If the Object Doctor is not "fixing" the collinear segments, this means that they are not unnecessary segments. Also, to the right of the options in the Object Doctor -- only those options with the little "hammer" icon are options that can potentially be fixed. Items without the hammer would need to be manually fixed (perhaps by deleting those parts, or by moving parts, or by remodeling). If you have a case where you think the Object Doctor should be removing collinear segments, feel free to copy that object to a new project, indicate which segments you think should be removed, and send it to so we can take a look.

DMclean Posted November 11, 2014 Author Share Posted November 11, 2014 Thanks. Each new problem gets me one step closer to understanding what the program is up to "behind the scenes" and how I can deal with things as they crop up. These forums are a priceless resource. Thanks to formZ for putting so much time and effort into them. Doug Link to comment Share on other sites More sharing options...

DMclean Posted November 12, 2014 Author Share Posted November 12, 2014 I've moved the questionable object into its own file and uploaded it to the ftp site. In its own file the error generated when I try to Boolean with it is a bit more specific now saying that the object is a degenerate solid, either a surface solid or a solid with co-incident faces with opposing normals... Tried turning on normals to find the faces... still working on that.. Thanks, Doug Link to comment Share on other sites More sharing options...
DMclean Posted November 12, 2014 Author Share Posted November 12, 2014 If I delete the top and bottom surfaces of the object, creating a surface of the main shape I can then successfully boolean that surface (e.g.. Surface Trim with a box). But if I then recreate the top and bottom (via create line from Outline) and sew those back onto the object (giving me a solid) then trying to split that object with the same box that just successfully trimmed the surface I wind up with the error...

Tech Posted November 12, 2014 Share Posted November 12, 2014 Hi Doug, Yes, that object is rather damaged. It looks like doing a Trim with the horizontal faces removed (and then replacing them when you are done if necessary) is probably going to be the easiest way to work around this...

DMclean Posted November 12, 2014 Author Share Posted November 12, 2014 After fussing with it for too long I just wound up rebuilding it. I did try working only with the "vertical" surfaces, but because the boolean I wanted to do wasn't a nice simple square like the test I could never get it to work properly.Did the booleans on basic geo to get the overall shape and then re-displaced it all at the end. Didn't give quite the variety that trying the other way would have, but it wound up working. The whole project (a Rock Cavern) is probably really better suited for a sculpting program, but I'm trying to see how far I can push things inside formZ. Thanks, Doug Hmm... what does "rather damaged" mean exactly? Link to comment Share on other sites More sharing options...
Tech Posted November 12, 2014 Share Posted November 12, 2014 I am not sure exactly because the Object Doctor is not finding these specific issues, but Triangulating all faces results in some intersecting faces, that looks to be caused by some faces being double sided in the object...

DMclean Posted November 12, 2014 Author Share Posted November 12, 2014 Yeah, I was noticing some weirdness along those lines as I tried various things as well. Was just hoping you had some secret way of knowing exactly what the weirdness was and how it got there.... D Link to comment Share on other sites More sharing options...
