That's great Fredo, look forward to it.

Fredo, first off let me thank you for all of your amazing plugins. I have a request for toposhaper. I don't know anything about coding and/or how difficult this would be. But in surface modeling programs you have the ability to add breaklines which make a more accurate surface. Do you think this can be added?

It is complex (it involves constrained Delaunay triangulation), but I finally built an algorithm (I use it already in FredoCorner). I will integrate it in TopoShaper when I can, along with a GUI refresh. This would look like a "from Contour", where you can also influence the terrain with additional guide points.

What I wonder how this could be input to the plugin. I'd like to see an example and how it might be implemented on UI level. I suppose edges that are horizontal can be introduced which are defined as firm intersections with the surface and not interpolated with the rest of the terrain. Working-in grades along retaining walls or building walls (rarely level) might be done be definition of point elevations.

My approach is usually working with existing terrain so after TopoShaper I massage it to new work as needed, sometimes cutting the surface where needed, sometimes moving points of the cut portions to fit to new walls or edges of pavement (e.g.). I see that where a vertical face is actually included in the original contours, weird results happen, but I generally rebuild that part or cover it in other geometry (like a model of the retaining wall it represents).

In general, it is better to conceive the terrain before adding decoration, houses, fences, etc...

But I'll think about what can be done, especially for roads.

This would be GREAT addition to this plugin. I do this work manually at present and it is tedious to say the least. This would be a great time saver.

Something interactive like this for roads would be superb.

And here is a open source road editor solution: https://gupea.ub.gu.se/bitstream/2077/23047/1/gupea_2077_23047_1.pdf

I think there is already a Plugin, InstantRoad by ValiArchitect.

Anyway, building such a plugin is independent from TopoShaper, as it should apply to any terrain, whatever method has been used to generate it.

But Instant road isn't interactive like in the link.

So what I'm doing is recreating our existing conditions surveys so that design can be brought in in 3D for some presentations and renders. When creating surfaces in Civil 3D our spot shots are used for the surface but so is our line work as breaklines for things such as roads, sidewalks, retaining walls. When I bring the contours into SU and create a surface using topo shaper sometimes the differences are pretty significant and just like KrisM I have to manually make adjustments to the surface which is tedious. Toposhaper already is a great plugin but I think having this feature will make it even better.

Hello,
I have never used Toposhaper before. I am trying to create a surface from the contour lines and I keep getting an error and the script aborts the operation. Attached is the Error:
Date: 16-Feb-19 12:25:07
An error occurred in CLEANSING
The operation is fully aborted

Can you advise if you use Linux under the cover?

MelResDes

I am not really familiar with Linux other than it is an OS that I don't think I use. I'm using a standard Windows 10 OS and Sketchup Pro 2019.

fredo6

I found the problem, which seems specific to SU2019.

I will publish a fix.

Hello Fredo,
Is there a tool I can use to manipulate a mesh created by Toposhaper? I am looking for a way to push or pull the grade around the house model I have placed on the mesh. I tried to use the native smoove tool in Sketchup but it did not want to cooperate with the Toposhaper mesh and it locked up.
Thanks!

You can use the native Sketchup Sandbox, or Artisanby Whaat (pay plugin).

MelResDes

Thank you. I tried to use the native sandbox tools but it locked up SketchUp. I will look into the Artisan plugin.
