belemaogan Posted January 12, 2018 Share Posted January 12, 2018 I tried to extract a box from my wall to create an opening, using the proboolean tool, but it didnt work. I am using 3ds max 2016, and all tthe probooolean options are set at default. the box disappeared without creating an opening. Link to comment Share on other sites More sharing options...
James Vella Posted January 12, 2018 Share Posted January 12, 2018 proboolean is not the most intuitive in 3dsmax, if you really want to boolean use the standard boolean tool it seems a bit more stable. I would recommend just cutting into the geometry or building the wall around the opening to begin with as booleans require some understanding as to how geometry intersects - basically any box that intersects with the edge of another box will have trouble understanding where to weld the geometry back together (or disappear), it also can break your geometry after collapsing back to mesh as it has to guess where to weld vertices and can pick a vertex which isnt ideal. Trying this on anything curved can also cause facets in the geometry and be more difficult to clean up than model correctly in the first place. 3dsmax boolean tools are far from anything you might have seen such as Alexey Vanzhula's Houdinis Direct Modelling Plugin - this was created with boolean workflow in mind and is very well optimized for this kind of workflow - not as much in 3dsmax. http://cgpress.org/archives/direct-modelling-hda-for-houdini-released.html Link to comment Share on other sites More sharing options...
belemaogan Posted January 12, 2018 Author Share Posted January 12, 2018 i tried using the boolean tool, but the result opening still needed to be caped in the inside walls, which means more work to do. is there a settings or way of using the proboolean or boolean tool such that i dont have to do more edits to the resulted opening?

James Vella Posted January 12, 2018 Share Posted January 12, 2018 make sure your intersecting box (the one you want to cut out) is all the way through the geometry. example: box intersecting all the way through the wall boolean operation box NOT intersecting all the way through the wall Link to comment Share on other sites More sharing options...
belemaogan Posted January 12, 2018 Author Share Posted January 12, 2018 The box went all through still no result. It's either the box disappears or the wall am trying to open dissapears and leaves a cut out of the box. Still no opening. What might be wrong?. All settings are at default.

James Vella Posted January 12, 2018 Share Posted January 12, 2018 like I mentioned earlier, make sure both boxes edges are not aligned - if they are one will disappear, just bring the box down a little further than the wall. Any edges/vertices that are on the same axis or intersecting will cause boolean to function in an odd way. Link to comment Share on other sites More sharing options...
belemaogan Posted January 12, 2018 Author Share Posted January 12, 2018 My scene is like this. I have various walls, and I need to create door and window openings, so I created boxes, autogrid on the walls and extruded. Outside these walls, I tried the probooleon command and it worked, but on my walls where I want to create door and window openings, the command is not working. It is either the box dissapears, my wall dissapears or I get an intersection of a part of the box. The box intersected the walls and its not at the edge. I need a solution Link to comment Share on other sites More sharing options...
ahmeds Posted January 12, 2018 Share Posted January 12, 2018 (edited) Did you check the normals of the box and wall? I usually reverse the normals of one of the objects when proboolean starts to misbehave, I also reset the xform sometimes. In my experience when boolean objects start disappearing it's a sign of bad geometry. Edited January 12, 2018 by ahmeds Link to comment Share on other sites More sharing options...
John Dollus Posted January 12, 2018 Share Posted January 12, 2018 (edited) make sure you are selecting the 'subtraction' operation. Default is 'Union' As a side note and bit of a critique, if capping/bridging open edges after the operation is a deal breaker for you and 'more work', Max may not be your thing.

belemaogan Posted January 12, 2018 Author Share Posted January 12, 2018 I know its subtraction. And my default is subtraction. Capping the open edges does not cap well. Its a door and window opening, the opening is not bounded by four edges so capping is distorted and even bridging. Then please where can I see the normals and reset the xforms Link to comment Share on other sites More sharing options...
Andrew _GF Posted January 13, 2018 Share Posted January 13, 2018 Did you try regular boolean? Sometimes one of those to works when the other doesn't. For me it looks like fixing a broken model is much more work than just modelling it with basic editable poly tools. In general you can unify normals by Normals modifier, also when you will select them in editable poly they are darker in viewport. Link to comment Share on other sites More sharing options...
belemaogan Posted January 13, 2018 Author Share Posted January 13, 2018 Thanks. i used the boolean operation, but i had to bridge the edges and cap the faces afterwards. i wanted a one time operation. my walls were generated from a one box tool command which i converted to editable poly and modeled round. I believe that was what made the proboolean operation not to work. Link to comment Share on other sites More sharing options...
