There are several downsides to modeling walls in a more complex landscape, including:
- Sloped walls can only be created via profile editing, which is a fairly imprecise method
- Landscape framework of design and layout tend to want to control where these happen in plan, so doing this in profile is often counter-intuitive
- If you have sloped walls that also curve, profile editing isn’t even an option
A solution that I commonly use for both of these issues is to use Floors.
While browsing through a Revit Forum post, I noticed that someone mentioned an app that could align Topo to Slab Edges. A quick search on the Autodesk Exchange turned up the Topo Align app.
I have not yet had the chance to test it out myself, but even after just briefly looking at its features, it seems like a very worthwhile Revit add-in. And for a cost of only 1.99 USD, it is also a really good deal. If you frequently work with Toposurfaces, I highly recommend that you check it out.
Railings are one of those architectural elements that are frequently used in the landscape. If you have stairs, ramps, or any sort of terrace, you will probably need a railing. And while Railings are relatively easy to create in Revit, they can be quite difficult to fine-tune (and detail) accurately.
One of the reasons that Railings are difficult to manage is that they are rather inflexible regarding both their structure and their hosts. Railings can be hosted to Floors, Stairs, Ramps, or just a Level, with the limitation being that they cannot host to shape-edited Floors. But there is a feature that will allow you to give a single Railing multiple and varying slopes.
