In our office we use casted shadows to denote depth on our exterior elevations, and recently I have noticed that we get shadows for no reason on elevations. If we modify the elevations the shadows change, but they are still there, as though we had a roof or slab just out of view. There are no objects which could be casting these shadows, we have checked. Often. Does anyone know how to remedy this?<BR /> <BR /> Also, in section, walls or otyher objects seem to dissapear for some reason. I patched my version and the walls cam eback, but has anyone else had this problem or know a possible solution? Thanks in advance.</T></DIV> Tue, 23 May 2023 13:23:11 GMT https://community.graphisoft.com/t5/Modeling/Sorry-if-this-is-old-news-but-phantom-shadows-and/m-p/56994#M28921 Anonymous 2023-05-23T13:23:11Z https://community.graphisoft.com/t5/Modeling/Sorry-if-this-is-old-news-but-phantom-shadows-and/m-p/56995#M28922 Prior to version10, errant shadows would often occur on our elevations (we do ours the same as you). In version 10 the only time I remember strange shadows appearing is when a roof plane has degenerated in some way. Another thing to consider is if you have a stray wall that is nested within another wall. That can produce some unwanted shadows and could explain the disappearance of things in section.
