It looks like you have the insertion point to be at the top, by your imgur link? It looks to me like the bottom is more 'fixed', so I'm going to start at the bottom right corner instead.Ĭompletely get rid of the 'WindowCrestWidthRight' and left targets. If I'm understanding what you're trying to do, this is going to be hugely easier to build from the bottom up, rather than the top down. ![]() I'm going to describe this slightly out of order (you'll have to go back and add stuff) to try to make it less confusing. See my quick sketch here: (JUST REALIZED I SKIPPED POINT P2 IN SKETCH, SORRY) If you want something else to happen at a different station, you just need to kick it through a different "If" statement. Hundreds or thousands of times per corridor. The entire process repeats each and every time the corridor builds at the next frequency point. keep asking questions, SAC is my favorite part of CAD :)įirst thing to remember is that SAC is that it's just a visualized programming loop. Yeah, this isn't too bad, but it is going to be confusing if it's your first time doing conditionals in Subassembly Composer (SAC). The trapezoid sill/berm/breakwater (terms I use interchangeably on this project) sits on a rectangular mattress. The overall design will be an offshore wall that has openings in it.Įdit: sketch and subassembly. I have an alignment and a profile that is steady at +3 elevation, when the profile ducks below +3 I want the width to expand. From -2 to -3 the subassembly projects to the surface.īasically. To complicate things, from -2 to-3 the crest width does not change. The equation would be x=7.5 - 2y for an assembly that I would mirror. As the elevation drops, the crest widens at a 2:1 ratio. ![]() The crest width of the breakwater changes according to the top elevation.Īt its highest elevation the width is 3 feet wide. My objective is to design a trapezoidal breakwater with a top elevation of +3 and bottom elevation of -3. I was hoping someone could help me with a subassembly setup I’m new to civil3d and I’m limited to creating basic subassemblies. Discussion is always welcome but try to do at least some basic Google searches before you reach out to others.Imgur links are usually best for screenshots. Screenshots or drawing files make troubleshooting easier, but don't include sensitive personal or corporate information.We can't help with problems that we can't understand. Keep titles succinct & specific, and use clear, descriptive language in the comments as much as possible.
