This 3D model was originally created with Sketchup 8 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This is Falkeneck. It is a 3d version of an HO model on my model railroad. One of my favourite models. This is made by Faller in Germany. It is only a shell. I would like to see someone (Paul? Eneroth?) put an interior in it. I scaled out the model 1" = 8', which is actually S Scale. To get HO scale, subtract 10% from S scale. My model used to sit in a moat, untill I redid my layout. This is what it used to look like. Now it is on a residential street on top of the helix. Bob UPDATE: Minor mistake: roof edge not pulled down at the rear to the right of the tower. Simply use Push-Pull to pull it down even with the other side, 12 inches. When you do, look under it. There will be a line from the corner to the edge. Delete it and the green will go away. Simply redo the green and you are updated. Thought I caught everything, OOPS! Fixed mine. PS: This is available in my Walthers 2009 HO Catalog. It is item number 272-130385 which is listed at $86.99. I think is still available. Oct 26 update: Paulwall has an interior in the structure, which is very nice!
