how we can generate such element’s geometry? I’m trying to get surface area of duct fittings ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/e/6/e6a1b7cb21783c65e717ae26a11ddbf613d85d84.png) [sample- duct fitting.rvt](https://forum.dynamobim.com/uploads/short-url/f9csYnZK9r3QsoMzMILW0QGCynj.rvt) (6.6 MB) ---

Can you post an RVT model with the geometry in question? There is likely a work-around but which one to go with is a bit difficult to advise on without first trying a few things. ---

What happens if Try element.solids? ---

@vishalghuge2500 , a workaround is _boundingbox_ ![grafik](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/7/a7451d1b6cac381c8d60d175e5858ed811c2aa15.png) ![grafik](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/7/677e24ba916703561b042380b11d3af73d0a9077.png) ![grafik](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/7/2/7230d4a59122315b7ea35654fc6b73848fb37674.png) ---

Try something here could probably work ![Skærmbillede 2024-04-18 090921](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/4/9/495f1d4cd3de7c51bacd6d9c0b625452de900f8d.png) ---

or an alternative way could be rebuild 😉 ![Skærmbillede 2024-04-18 091954](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/a/d/ad1d6cd25d9b1e625bbd1cdfe74c2cfc878f7bfd.png) ---

apologies for resurrecting an old comment, but I tried to redraw this fitting using your method and had a few questions. 1. How do I see a 3d version of the new loft? 2. How do i use that new loft to calculate the surface area? Thanks ---
