    Trench Drain Simple Shape

    I'm trying to represent a trench drain with a built in slope I'm simply planning on making a extrusion in elevation of a rectangle with the bottom slanted or straight. I need each end of the rectangle to be controlled independently so that the angle of the bottom line changes. Is this possible to do. It seems like it should be simple to do, but I can't seem to get an endpoint of a line to attach to a reference plane. I want to have 33 different sizes that range from 3.998" on the short and 4.334" on the long end to 11.726" on the short and 12.062" on the long end. I'm also planning to use type catalog for this because most jobs will only need a couple of these drains. I haven't gotten far into this family because I get frustrated that I can't make a shape that changes the depths of both ends and the angle of the bottom at the same time. Whenever I try adjusting the reference line when I think I'm starting to make progress it says its constrained.

    You need to align LOCK the end of the line to the plane, tab till you see the ednpoint

    Thanks, I got it working. I don't know how I forget things like that.

    Is there a way to get a parameter to be in inches or better yet decimal inches? I created a base family type and then exported my family to the TXT file, but the dimensions for my two ends are in decimal feet instead of inches. In Revit they appear as architectural units so my one end that is 5.760" reads as 0' 5 195/256" while in the TXT its 0.480143229167.

    Could I just edit the TXT file's Parameter declaration to be "Dim-Depth-Large##LENGTH##INCH" instead of "Dim-Depth-Large##LENGTH##FEET"? I would then have to change the base parameter to 5.760.

    Also as a side note when I made the TXT it only created one line. Can I start a new line at the beginning of the first type and start a new line for each new type I make? I also heard that I can get rid of any parameter that wont be changing from type to type. Do I get rid of the declaration as well?
