pafurijazSooner or later I will be able to do it, for now it seems that something is improving, I managed to create an <a href="https://mastodon.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> file exported directly by <a href="https://mastodon.social/tags/Blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender</a>, and also a <a href="https://mastodon.social/tags/STEP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#STEP</a> file always with the same <a href="https://mastodon.social/tags/Python" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Python</a> add-on. <a href="https://mastodon.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a> <a href="https://mastodon.social/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a> <a href="https://mastodon.social/tags/SubD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SubD</a> <a href="https://mastodon.social/tags/nurbs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nurbs</a>

pafurijazI've asked to <a href="https://mastodon.social/tags/AI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AI</a>, an add-on to export <a href="https://mastodon.social/tags/SubD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SubD</a> to <a href="https://mastodon.social/tags/NURBS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#NURBS</a> from <a href="https://mastodon.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a>, the add-on managed to export something to both IGES and STEP, there are no errors, the exported files contain data structures but unfortunately any <a href="https://mastodon.social/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a> app managed to open those, although that seem like a failure, it's not, in fact it is the first time that I get an add-on that exports both in <a href="https://mastodon.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> and in <a href="https://mastodon.social/tags/STEP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#STEP</a> directly from <a href="https://mastodon.social/tags/Blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender</a> without using external library, maybe next time I could be able to have a working add-on.

pafurijazHere a little guide on how import a <a href="https://mastodon.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> <a href="https://mastodon.social/tags/Nurbs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Nurbs</a> surfaces ready for Subdivision Modifiers, isn't always a suitable workflow, but can help maybe in some cases. <a href="https://mastodon.social/tags/blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#blender</a> <a href="https://mastodon.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a> <a href="https://mastodon.social/tags/Blender3D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender3D</a> <a href="https://blenderartists.org/t/how-import-iges-surface-topology-into-blender-ready-for-subd/1556580" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://blenderartists.org/t/how-import-iges-surface-topology-into-blender-ready-for-subd/1556580</a>

pafurijazOK I found a way to import <a href="https://mastodon.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> files into <a href="https://mastodon.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a> with the same topology as Nurbs surfaces, as soon as I have done some tests I will make a post on <a href="https://mastodon.social/tags/Blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender</a> Aritst to share this workaround, this allow the use of SubD modifiers on original Nurbs imported as OBJ in <a href="https://mastodon.social/tags/Blender3D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender3D</a>

pafurijazA new Version of <a href="https://mastodon.social/tags/FreeShip" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeShip</a> is out I helped the developer to add a new import format, this now helps many that need to convert Subdivision Surfaces into <a href="https://mastodon.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a>, because now you can import VRML2 files I use <a href="https://mastodon.social/tags/Blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender</a> to export into OBJ and then I convert OBJ into VRML2 with <a href="https://mastodon.social/tags/Wings3D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Wings3D</a> an application that preserve the quad topology, also <a href="https://mastodon.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a>, and still developed, sadly others app do a triangulations and you lose the topology information. <a href="https://mastodon.social/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a> <a href="https://mastodon.social/tags/boat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#boat</a> <a href="https://mastodon.social/tags/design" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#design</a> <a href="https://github.com/markmal/freeship-plus-in-lazarus/releases/tag/v5.3.1.537" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://github.com/markmal/freeship-plus-in-lazarus/releases/tag/v5.3.1.537</a>

pafurijazThe <a href="https://mstdn.social/tags/SubD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SubD</a> conversion of <a href="https://mstdn.social/tags/FreeShip" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FreeShip</a> into <a href="https://mstdn.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> is still unmatched for me, is an old Pascal code that works perfectly, very light file with surfaces with the same topology of the mesh cages <a href="https://mstdn.social/tags/nurbs" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#nurbs</a> <a href="https://mstdn.social/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a> <a href="https://mstdn.social/tags/plasticity3D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#plasticity3D</a> <a href="https://mstdn.social/tags/Moi3D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Moi3D</a> <a href="https://mstdn.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a> <a href="https://mstdn.social/tags/Blender3D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender3D</a> <a href="https://mstdn.social/tags/fc3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#fc3d</a> <a href="https://mstdn.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a><a href="https://blenderartists.org/t/from-blender-subdivision-to-n-u-r-b-s-iges-for-free/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://blenderartists.org/t/from-blender-subdivision-to-n-u-r-b-s-iges-for-free/</a>

pafurijazI've just dropped two <a href="https://mstdn.social/tags/propellers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#propellers</a> done with <a href="https://mstdn.social/tags/SubD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SubD</a> in <a href="https://mstdn.social/tags/Blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender</a> and converted into <a href="https://mstdn.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> and then to other <a href="https://mstdn.social/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a> formats. The models in low poly can be used with SubD modifier and they are also UV-mapped too. Useful for your <a href="https://mstdn.social/tags/boats" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#boats</a> model in every place from <a href="https://mstdn.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a> to CADs. <a href="https://mstdn.social/tags/Blender3D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender3D</a> <a href="https://mstdn.social/tags/boat" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#boat</a> <a href="https://mstdn.social/tags/design" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#design</a> <a href="https://grabcad.com/pa.furijaz-1/models" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://grabcad.com/pa.furijaz-1/models</a>

pafurijazIf someone need a simple <a href="https://mstdn.social/tags/propellers" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#propellers</a> and <a href="https://mstdn.social/tags/planes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#planes</a> generators there is a nice parametric <a href="https://mstdn.social/tags/opensource" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#opensource</a> application that export geometries into <a href="https://mstdn.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> or <a href="https://mstdn.social/tags/STEP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#STEP</a>. <a href="https://openvsp.org/" rel="nofollow noopener noreferrer" target="_blank">https://openvsp.org/</a>

pafurijazLet's take stock of the situation. <a href="https://mstdn.social/tags/Blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender</a> isn't a <a href="https://mstdn.social/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a>, but that doesn't mean it can't be used in this field too, if you just know how. Accurately creating precise Nurbs surfaces requires considerable effort and skill using the tools provided, and with the ability to export to <a href="https://mstdn.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> it is possible to create precise surfaces with much less effort than using programs such as <a href="https://mstdn.social/tags/Rhino" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Rhino</a> or <a href="https://mstdn.social/tags/Alias" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Alias</a>, in fact these modelers now have also the possibility to work with this type of geometry. <a href="https://mstdn.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a>

pafurijazA tip for those who occasionally use the <a href="https://mstdn.social/tags/IGES" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IGES</a> add-on for <a href="https://mstdn.social/tags/Blender" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Blender</a> to export SubDs to IGES from Blender, avoid level 3 and 2 because they add an excessive subdivision in the critical areas which should be reconstructed later. Here IGES imported in <a href="https://mstdn.social/tags/Plasticity" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Plasticity</a> an upcoming <a href="https://mstdn.social/tags/CAD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CAD</a> Export Add-on <a href="https://mstdn.social/tags/b3d" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#b3d</a> <a href="https://dsculptor.gumroad.com/l/exportiges" rel="nofollow noopener noreferrer" target="_blank">https://dsculptor.gumroad.com/l/exportiges</a>
