Thank you all, but i need to use this tool in modelbuilder. When i used base hights in arcscene with z values the result is good. But if i use extrusions with z values, the result is not good (lines). I uploded pictures of situation with base heights and extrusion. It is historical chapel (back side). Is it posible to create multipatch file from txt file (points with xyz) in modelbuilder? I already done Multipatch model using Google Sketchup and Arcscene, but i need also the another option (Modelbuilder, if is it posible).
