Vertical retaining wall in sandbox
-
Hi there!
Simple SKP drawing below
I am buying some land here in THailand.
It comprises four land titles, and it has 8 sides made together making a sort of vaguely triangular or sector shape.
I would like to Sandbox the land and also it's surroundings for some metres.
One of the existing sides A > B below, which will therefore be inside my projected drawing, is a retaining wall about 2 metres high. Behind it, outside my land, the soil goes to a higher level. The land nearby the wall eases downwards....and there is a raised track outside then down into a river. I will be raising some or all of my land, probably on three different levels and maybe incorporating a moat or pond. The reasons I'm doing this drawing is to play with different levels and see what various designs of house I might produce look like stamped onto it.-
As the sides of my land are not following the axes is it impossible to have a vertical wall inside the drawing? (even if I MADE one side follow so the axes weren't N S E W would it be possible to make a vertical shape?

I'm using a somewhat aging Macbook with only 2gigs of RAM. What's the max number of squares I could reasonably have in my grid and not crash from overload?
Thanks so much!

Hi, I did not download your skp. However, I can give you some initial information.
An answer to question 1: The program has global xyz axes always in effect. So, by vertical you mean the z axis then yes you can make vertical constructions. If you mean perpendicular(normal) to the model surface, you can do that too.You can also rotate the model to align with the xyz if desired, so that NSEW agree, or not. Or you can make a local, temporary set of xyz for the model or any part of it. It is best to use components and/ or groups when using local axes. You used the term "stamp". Make your terrain, or portion of it a group. Position your grouped house above the location you would like to stamp it. Select the Stamp tool, follow the instructions on the bottom of your window. I believe it is select the surface on which to stamp, then select the object to stamp onto the surface.
An answer to question 2: It is always best to make a grid as sparse as possible. A land surveyor would do the same thing. I am not sure what common practice is in your locale, but a grid for land parcels might be 4-5 metres?, unless there is significant vertical variation. This would necessitate use of contours rather than grid. I am not sure what vertical unit/interval is used, perhaps 1/2 meter? So, if you have a contour map, you can create a TIN with Sandbox "From Contours".
EDIT: I hope this helps in some way, and perhaps the one who downloaded the skp has more to add. -

THankyou Mitcorb...
the question is.....how? I'm talking about Smoove here for shaping the land. Seems to me a surface can only rise from one line on the grid to the next line on the grid. And say that line is one metre or whatever it is away.....so if the rise is for example 2 metres how can it be vertical, it's an angle whose TAN will be 2 isn't it?
This is one reason I asked about my max number of grid lines for a 2gig Macbook, as the grid size affects my question. My land "triangle" has sides about 60 metres or so, so if I spread out a bit further to incorporate neighbouring houses and land shape, a 1 metre grid (nice) would have maybe 120 or 150 grid lines on both x and y directions. I'm guessing that's way too much? But 1 metre spacings would give nice shape to the fairly small river.Thankyou for your comments about groups and components etc. I had already half figured I need to make the land one group and possible buildings separate components to try stamping (a new skill I'll try), correct? (I don't have contours or any other program....just an amateur).
To make things more real, less dry, and perhaps understandable I'll upload some pics.
The first looks at the wall on line AB
Second the track about 140cm above the base land level
Third the river down some way from the track
Fourth the view just to show you why I want to live there.....cheers Cheeryble
sorry photos not showing try again later

With regards to Smoove, you may want to look at some of the video tutorials on the use of the Sandbox. It also may help to practice on some less complex examples. I did a quick refresher on the use of Drape and Stamp just using a cube above a sloping rectangle before responding to your query. Do searches with keywords relating to your issue in this forum.
I may have misunderstood some of your reply. -
