Sandbox tools
-
Hello!
I have one problem and I can't figure out what I have made wrong.
Here is clean topography.
Here is mesh created correctly.
But when I use this two lines for mesh then mesh is created wrong:
Please help me with this problem. What I'm doing wrong or this is some sandbox bug?

Hi Aidus,
It's hard to tell anything certain from these pictures but those two lines seem to meander a bit illogically. A contour line is supposed to follow a certain height on the Z axis but these lines are making very sharp turns and run parallel with themselves while they don't form any kind of closed loop as one would suppose.
But this is certainly just guessing.

I think that sandbox does not include some topography lines in mesh. Just don't knov reason.
-
my guess is that the difference between high detail and low detail is too much for the sandbox tool. maybe you can overcome this problem by creating the terrain in several pieces and stitching them together manually...
-
Ok. But in this case I can call this a sketchup sandbox bug?
So, problem solved! I have divided those red straight lines in 11 segments and now mesh shows up correct! Well I think this is just stupid. If I have very large topography then this process will take very long time to divide all those straight lines
Thanks google for improved su 7 !!! -
Yes,this must be the problem.
I played around with the topo and found out that where the long,straight lines were, were the glitches as well. Lines ran underneath everywhere without consistently forming the mesh.
The problem is that the Sandbox tool will not divide straight lines (as you properly guessed the solution would be) but connects to the closest endpoint.In case there is a long, straight line in the proximity, whose endpoint is further than one over the line, the SB tool will connect to this latter one instead (which is its "logical" thinking.
Now you have these long,straight lines / roads and such in the mesh and they are usually within some geometry that is supposed to be draped onto the already made mesh not to be created with it.
I can see the intention of making it together and examining the linework, it really seemed to be okay - except the above mentioned behaviour of the SB tool.
Well,I'm glad at least that you found the solution.
-
that was a great and logical explanation. thaks, Gaieus. now it all makes sense. good that you found a solution for your problem, Aidus.
this information may come in quite handy in future -
plot-paris just with Your help I solved my problem
now I understand why su acting so with my topo
Thanks Gaieus for info!
