I couldn't agree more!Originally Posted by Chad Smith
From the beginning of my love with REVIT till short time ago, I always struggled with PADS because I was taught so.
However, when my frustration reached the peak I switched entirely to toposurface manipulation, using only "Split", "Merge" and "Graded Region" tools. And let me tell you that I am much faster overall and by far less stressed without PADS, even if repositioning of the house on SITE (in any way) means re-creation of the whole CUT/FILL and battering arrangement again...
I am not coming back to the grim business of PADS, unless they are totally overhauled...
Now, for the short outline of my way of toposurface manipulation (perhaps it may prove useful for some new REVIT adventurers...):
1)Normally, you create a toposurface in the NEW phase (since most likely you work in the NEW phase anyway)
2)If so, after creation of the toposurface, change its phase to EXISTING (since it already exists on Site…) see picture 1a.
3)Using “Split Surface” tool, create your desired building PLATFORM (for not wanting to use the term “PAD”) of any desired shape see picture 1b.
4)Our new building Platform is defined but it still has the original slope. We have to change its grade to flat – using “Graded Region” tool. Note that since our toposurface is already in the previous phase (NEW is our current working phase, so Existing is previous to current…), we don’t need to worry about this anymore… see picture 1c.
5)For the purpose of this exercise, I assumed the CUT/FILL line to be at RL 12500.
The next step is to choose all the PLATFORM boundary points and change their elevation to 12500, effectively “levelling” our building PLATFORM see picture 1d.
6)Right now we should have situation shown on picture 2.
7)Repeating earlier “Split Surface” and “Graded Region” techniques, we create CUT/FILL embankments see pictures 3a, b, c.
The final results are shown on pictures 4a, b, and c.
Now, if for any reason we want to redo anything, there is a "Merge Surface" tool...
