Poot Posted May 11, 2021 Share Posted May 11, 2021 (edited) Hi everyone, I am having a problem where the proposed site model contours are behaving badly inside a hole within a hardscape. You can see the existing contours below, and the shape of the paved area which will take an elevation of 44m. When I create the hardscape (slab modifier), the contours continue to pop up in the cutout area...which means you have geometry spiking up 1-2m from the hardscape I would obviously prefer if this did not happen, since I cant seem to change this even if I put another slab inside that area. Is the only alternative to modify the existing contours so that they do not pass through that hole? Even when I adjust existing contours out of the way, the terrain comes up above the landscape area I have placed within the hardscape... Much thanks....

jpccrodrigues Posted May 11, 2021 Share Posted May 11, 2021 Try using a site modifier inside of the "holes", not forgetting to include a grade limit to the site model. Give it a try 2 Quote Link to comment
Vectorworks, Inc Employee Eric Gilbey, PLA Posted May 11, 2021 Vectorworks, Inc Employee Share Posted May 11, 2021 Yes, João is right...the area inside of the hardscape modification does not have anything telling it how to perform, so it is trying to go back to what it was within the confines of that small opening. Placing a pad (offset the opening shape by a few centimeters) and convert that to a site modifier (pad configuration) at the elevation you prefer that planting area surface to be, and it should do what you seek. 2 Quote Link to comment
Poot Posted May 28, 2021 Author Share Posted May 28, 2021 Thanks @Eric Gilbey, PLA & @jpccrodrigues . Forgot to write back that setting grade limits helped solve the problem. I ended up putting it around most of the site....which worked pretty well. I don't know if there are any downsides to that approach? Cheers Quote Link to comment
Vectorworks, Inc Employee Eric Gilbey, PLA Posted May 29, 2021 Vectorworks, Inc Employee Share Posted May 29, 2021 The closest thing to a downside of putting a grade limit around the site is only that it might be more accurate for cut and fill if the grade limit is closer to the area being affected. Note in the images below...The first image is without a grade limit, and the proposed grading is not regulated well. The second image shows a grade limit of about 30' from the modifying pad, and the third image shows a grade limit of about 15' from the modifying pad. If the resulting slopes are favorable, the tighter to the modifying work is better for the amount of cut/fill you would propose. Much like it would be on the actual site. If your placement of the grade limit did not cause more proposed grading over the area of the site than you expected, then no need to change. 2 Quote Link to comment
