I noticed the same problem with the models free of archive3d.net
in this case the object is decomposed. I'm confused

because importing a .3ds files into sketchup (free models at the official site furnishings RODA) I have problems with the surfaces? as a tool I can use to create the faces rapidly? Open the file with 3dsmax shows no errors.

sorry for my english ... I'm Italian ahahahah pessimo=bad

The material editor is really pessimo.si may be required to introduce a more immediate ... an archive preview where you can enter your own collections! as well as for example fryrender material editor .... much more practical

Look in the subfolder, in the file 'housebuilder_sections.txt' there are the lists of section-types and sizes etc...
Make a copy of that file, edit the file to show the sections you want in the single-line as shown for each of the four types; use the same 'syntax' as the original sizes in 'mm' [aaxbb|aaaxbbb|... etc], test it and if it works with your new custom sizes you've cooking-with-gas; if NOT then you've always got the original version to revert to...[attachment=0:36niodui]<!-- ia0 -->Capture.PNG<!-- ia0 -->[/attachment:36niodui]
