Sketchup to pepakura problems
-
I am having trouble using sketchup 8 with the shareware program pepakura, which allows you to unfold a 3d model into paper templates to make it in paper craft. The problem I have is that when I open the sketchup file in pepakura, it works fine, but some of the faces of what I have made are not joined so it will not unfold properly. When I go into sketchup, there is no way that I can find to join these faces. My models are fairly complicated and are not just boxes or simple shapes, so what I wanted to know was does anybody know how to make all the faces joined in pepakura.
Thanks in advance.

Have you tried using 3DS files or Objs? They work better with Pepakura in my limited experience with the program.

Are your exported objects manifold solids beforehand ?
If not then use one of the available tools to fix them... -

Also I only have the free version of sketchup so I can only export in skp and collada.
Thanks in advance.

If you select a group or component-instance and then use Entity Info it returns some details in a dialog. If it has the word 'Solid' in its title then it's a 'manifold-solid' - like a simple 3d 'box'.
If it doesn't have that word in its title then it's not a 'solid' - it has holes, internal partitions or 'flaps' that don't meet other faces etc...
Manifold solids unfold relatively easily, because every edge has two faces - no more, no less.
Other non-manifold forms will often have problems as they will have an edge can have more or fewer faces that it must try to unfold... -
tankyou. that made perfect sense and i have checked some of my models and found that they are not manifold solids. what were these tools you were mentioning that can fix them and where could i get them.
thanks in advance.

forget my last post i just found that when something is a group it counts as a solid but when the same object is not grouped it is an entity. what does this mean?
