Toposolids - pattern placing points from an imported file is less accurate / practical than Toposurface

[AMillarSOA]

For the first time in the ~ten years I have been keeping my "WTF Revit" list of complaints posted on the tackboard on my desk, I was finally able to scratch four items off of it with the release of toposolids!  So.... Yeah, quite excited by this early version and hope it sees a lot more development.

One issue of note so far: toposolids are not making very accurate geometry from contours, toposurfaces seemed to generate a more effective pattern of points along contours, while toposolids generated from imports are only creating points on vertices of import polylines.  This results in a lot of vertices in Revit 2024 crossing the wrong direction over contours.

An improvement to the pattern or a definable maximum spacing of points on a line would help a lot with this.

Split lines finally being available in Revit topography is a godsend, but having to manually trace half the contours with them or add points manually is going to be a nightmare...  I think for now we are going to have to stick to importing to toposurfaces in 2023, then upgrading the model to get the toposurface into 2024 to get better imported points.

Edit: I've attached a couple images of the differences.  In the Revit 2024 toposolid image, I've quickly highlighted the areas I noticed so far where geometry is crossing the contours incorrectly.  In the 2023 version, I can't really see any locations that do this, and it sort of looks like this is just down to 2024 picking less points on contours.

(Also, Split lines badly need a "pick lines" option and always has needed that... and subdivisions need to have a structure like floors, and offset positive or negative cutting into topography, though I hope that latter is at least on the drawing board already)

I'm having the same issue. There should be a setting to increase the point spacing for better accuracy from an import. I'm spending a lot of time tuning up a toposolid to reflect the accuracy of a survey by placing many more point.

I couldn't agree more with you. We are working quite a lot with complicated topography (cliffs, sloped terrains etc) and when toposolids appeared I though "at last". But as you point out, the accurancy of the contouring is below average. I actually need double the work to make the toposolid appear as smooth as the underlying contour import. I've noticed that the bigger the toposolid, the worst the contours. And the most important issue here is that in permit processes the underlying topo in revit doesn't match the surveyor's one leading to various other problems..

It would be ideal if we could place points along a countour with a pick line tool or something, at least that way any issues would be fixed faster. It's just a pitty that Revit still doesn't feature proper landascape tools, leaving it to random add-ons.

Just adding that this issue continues in 2024.1.

(got hopeful when we saw toposurface enhancements in the release notes, but it's just 'simplify toposurface' which makes the problem even worse)

Until this issue is fixed, I highly recommend you use the workaround of importing your toposurfaces in 2023, then upgrade them to toposolids and bring them into your project in 2024, as this carries over the more accurate point locations.

Ι actually tried it. The toposurface was smooth as the survey but as soon as I converted it to toposolids the contours lost their definition again..

Do you have any other suggestions?

Same headache here.. Anyone managed to solve?

I have tried

It works, but takes long time and better to repeat. Toposolid is become a bit flatten afterwards 😞
