I downloaded Sketchup 2013, and that fixed it. I hate that Slicer5 does a better job, but I have already paid for SliceModeler v1.4, although I cannot seem to find the download link for it. I have been playing around with version 1.3. Thanks for your help.

I tried Slicer5 as you suggested, but I am having the same problem with it as I had with SliceModeler. With both of these the last option is to create a flattened copy of the slices, but it does nothing when I press yes.Otherwise it works great for the intended purposes.

Googling this question either returned the unfold tool, or a discussion on flattening 3-D objects so that they look like floor plans. I do not wish to do either of those. I wish to take several different separately grouped objects and lay them down spaced out on the same axis. Much like the layout of objects that will be cut on a CNC machine. The grouped objects I am using were produced using the SliceModeler plugin. They are not completely flat, in a 2-D sense, I just want to lay them flat on a 3-D axis.The gap produced by SliceModeler requires some depth in each slice to make the pieces interlock. Is there a plugin that can help me do this?

I watched this video on youtube of Chronolux 1.2

It was so close to what I wanted that it made me laugh in a "did they just read my mind?" kind of way. The different colors, and the example with a contour looking map made my eyes pop! Thank you Chris for pointing me towards this plugin. I really could not have asked for a better answer.

Is there a plugin that can determine the hours of sunlight that shines on different areas of a landscape, or a place to request such a plugin? I would like to plan out the placement of plants in a yard based on the number of sunlight hours each area receives. TIG's ShadowProjector plugin does something close to what I want. If it projected the shadows for an entire day (maybe every half hour) with the shadows overlapping. I tried overlapping shadows with this plugin, but it doesn't seem to work. If you could overlap the shadows, and then add 30 minutes for every time a shadow overlapped, and somehow label it with the sum of the shadow hours subtracted from total sunlight hours in a day. (possibly like the elevation is done on a contour map) it would be perfect. This would be invaluable in determining what types of plants to place in different areas based on their light requirements.

Does this plugin maintain the original dimensions of the object being draped? I am trying to determine the amount of material I would need to vacuum form plastic over an object. Thank you for the advice.

I find the built in drape tool to be more of a projection tool. Where it projects a pattern onto an irregular surface. Is there a plugin that would for example take a 2 dimensional plain and drape it over a 3 dimensional surface like you would see if you threw a blanket over a soccer ball? Thanks!

As usual when you think you have something finished a bug is found. I downloaded a model from the 3d warehouse, and attempted to make it dynamic. It seems to work exactly as planned until I enter the number 12 in the NumberOfRacks section of the Components option dialogue box. Then I only get 11 racks. It works fine when I enter 11 and 13. If anyone would care to take a look at it you can find it here: http://sketchup.google.com/3dwarehouse/details?mid=b313851cdf642864ffdd141d4f473266&result=4 Thank you.

Thank you Gaieus. The Shift + Eraser Tool trick helped to hide most of it.

You can see what I am referring to in the circled portions.
