How is the best way/plugin to close a hole in a terrain mesh?
I have 2 groups, terrain and building and I need close a hole, see the image.

Hi,

I have a terrain generate by TopoShaper amd I want project items on it.
I can use Drape tool from Sandbox toolbar but in this way the projection is part of terrain (drape tool add mesh on terrain. I need have the projection as separate object and show/hide it on terrain.

Is there a way or a plugin for it?

I need to tiling a wall.
I have to put a decor, so wall tiles are not all the same.

Can different textures be inserted at different points on the wall?

I installed the last version but I have only the "box" tools, no "target" tools. Any ideas?

Thanks for "skatter ($$) o raytracer (free) o component spray (free)" suggestion.
Visualizer doesn't work on SketchUp 2016.

I have a floor plan of an attic very irregular:

I have spend many time to draw the roof and the result is not a good result:

What is the best way to draw a roof like this (irregular plan)?
Are there some plugins that can help me?

I have assign material to group and all group items but I get the same result.

This is the model: https://1drv.ms/u/s!AsM-9m6nUHA9qTnr9qFgnsQdk4LD
This is the grass v-ray material: https://1drv.ms/u/s!AsM-9m6nUHA9qTpQIcNlENyawbhQ

Is the terrain grouped by itself?

Yes

@panixia said:

looks like you are using displacement without the "keep continuity" option (or whatever that's called in sketchup vray i don't remember) turned off, is that?!?

"keep continuity" is active on VRAY.
In any case the problem is the displacement. With material without "displacement" I don't have this problem.

On SketchUp I don't see these lines:

I don't understand because I see them on render

I tried to use VRAY for first time.
I get a problem with terrain model. As you can see on picture on grass there are mesh lines.

Where am I doing wrong?

I have created a terrain by TopoShaper plugin and isocontour.
Part of the land is flat, but one part is uneven.
I have to edit the uneven part of the land to make it flat. I have already tried to use the "model" tool from sandbox toolbar but also if I try to recude radius I cannot get a good result because I must move least 3 edges.

Is there a way to accurately model the terrain?

After created a terrain, is there a way to show the "grid" on it? I see only the surface but would be nice to see the points of the grid for editing.

I have some problem when there are 2 coincident surfaces.
See the image:

Is there a way to show only the right surface?

Another small question, is possible change hide/show entity between different views?

I need draw a small house. I would like allow to hide/show items so it's possible see the interior of the house.
So I have create this:

Any color is a group (the colors are just to make you understand, I have to use materials).
I can hide the roof and see the interior...

First question: is this the right way to use SketckUp?

Secondo question: If Yes, is there a way to hide line between 2 colors and use textures like single surface?

Third question: is there a way to have a solid sections? I have try SolidSection plugin but it not work very well.
