Just to explain more clearly: I made an aspen tree with aspen "leaf" level 3 components grouped together inside a level 2 "branch" component grouped together inside a level 1 "tree" component. Then I used the aspen tree component to make a birch tree in a new file. I replaced the Aspen leaf .tif texture with birch leaf .tif, and changed the branch shapes a bit. Then I make a new landscape file and insert the birch tree. Later I insert the aspen tree. However the Aspen leaf.tif texture is now replaced with the birch leaf .tif texture. It seems SketchUp remembers that the leaf level 3 component was the same. Changing the components and sub-component name before importing makes no difference. The only thing that helps is exploding the leaf component. This would be a nice solution, except the tree is much more complex than explained above, with tons of different level 3 leaf components, which are not easy to find. Also I modeled a handful of trees before discovering this problem. So, either a solution to the issue of help figuring out the logic behind this problem would be greatly appreciated.

JPP is the best one! Projections by Didier has also a push pull multiple but less sophisticated! PS I suppose that you have seen that : When you have made one JPP simple or multiple you have just to make a double click on the following surface one by one for have the same JPP! Look also Architect Tools by Thomthom for the DWG files inside SketchUp! It has functions for automatically create buildings from the DWG!

I remember seeing a YouTube video from a guy using LOD trees in Blender Game engine. The video wasn't great but the workflow show lo poly tree generation.

If you use the Sketchucation plugin store, you will later have the possibility to use the update function for installed plugins... Or if you update your SU version, you can use the bundle function to install fresh copies of all plugins with one click...

Even with all it's flaws, I'd only go back to Autocad from Layout if I was really forced to do so. And rest assured that I'm a very very active critic of Layout... (But then again I'm also an active critic of my mother, my father, my wife, my three kids, and myself...)

If I isolate a small part of the terrain by copying and pasting it outside, the section cut works normally. It appears to be related to size of the terrain.

Hi folks. See added scene 4 in this SU file for an idea that doesn't affect the terrain since it is a separate group. Any of the blocks can be made as a component or group and then manipulated as you wish by moving or rotating. You can use the Push/Pull tool to modify the dimensions of each making it shorter/longer or narrower/wider. Rectangle on topo.skp

the road elements need to be in a different group not to interact with terrain. Use a thickening plugin to give sides to the road or whatever it is, which reach down or intersect terrain so it is not a just a magic carpet floating above. But if you must model the terrain for cut and fill as is always done in reality it gets complicated and, short of more advanced software, careful modeling is required. Always save a group of the original terrain for later adjustments and reference.

Open GL details says: Quadro K3100/PCIe/SSE2 GL v. 4.5.0 NVIDEA 347.52

So why not use Work plane by Tig ? Or draw the rectangle above and in side view Move at the level you yant? or use Drop Vertices by Tig ? Or Raytracer by Thomthom [image: G2jq_drop.gif] Or this one?
