use railclone to build a wall... from the top down...
« on: June 26, 2015, 03:25:37 PM »
Hi,

How can I use railclone to build a wall, from the top down, sloping (spline goes over contours) and sloping back (wall face leans)?

The sketch below shows the section I want to create. The stones on the right should be randomly selected different lengths (that I can do), with a coping on top (not sure hoe to achieve this inside one railclone). I presume the back face (left) of the wall should be a separate railclone. Should the coping be separate too? The black cross marks where I the spline should be, which would allow me to make another railclone fro the coping, but don't mind where it is if there is another solution.



Cheers,

Bill

Hi Bill,

Please take a look at the attached file for a possible solution. I have moved the spline to the ground as it is easier, I hope that isn't a problem.



The style uses 3 generators, one for the coping, one for the sloped wall and another for the upright wall. The straight wall and the coping are pretty straightforward, while the sloped wall is only slightly more complex as it uses a trigonometric expression to maintain the position in relation to the spline and cap stones as you increase or decrease the number of courses. I've also added a couple of expressions to calculate the Z Offset of the cap stones, and the position of the back wall automatically.

To follow the contours of the surface I'm afraid I've had to use our Glue utility to conform the spline to the surface. Unfortunately RailClone's surface feature doesn't work with an A2S generator with the X Rotate, as is used in this case (I'll look into this).

The attached file has some notes to explain how it works but please let me know if you have any further questions.

Many thanks,

Paul
