Hi All, I’m trying to loft multiple cross sections to ultimately create one solid. From the points on a segmented line, I’m able to create the cross sections. When I try to loft them, there’s an inconsistency in the loft action. ![Wall](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/d/c/dcc8b3e0fcb04fc9c0ce5b99a6a22066e769c3f8.jpg) The solid I’m trying to create is part of a wall, I’m able to create other sections of the wall without a problem. Anybody encoutered the same problem when using the Solid.byLoft node? Perhaps someone found a solutions or knows what the problem is… Thanks in advance! I’ve added my graph and the cad source file from which I create the cross sections.

Try the loft by rails node as one possible fix. ---

@jacob.small Thanks for your reply. This might work, but this one isn’t really suitable for me since all the cross sections are different… ---

I likely have the wrong node name but you can thread multiple cross sections along a rail with the node I’m thinking of. I’m off on a day trip to a museum so I won’t be able to check (my international data is too slow so it won’t load the dictionary for me - it times out) but I’ll try to find it when I get wifi later tonight. ---

@jacob.small I understand. Perhaps you mean one of these? ![Solidbyrails](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/8/9/890112411492aea19c59a03af20df763eb34cf58.PNG) ---

@jacob.small I’ve tried Solid.Byloft using guideCurves. This gives met the following result: ![Wall hollow](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/6/e/6ea31ec6687e3579fcf03166fd7b8cf47a9ad884.jpg) The result is sort of a hollow tube… Any ideas? ---

Can you post your dyn and source files for me to recreate this issue? Making a dataset that replicates your problem proved to be problematic (though it felt like it should be so simple - hard to recreate a failure unless you know why it’s failing). ---

Now I ran the graph in Civil 3D and not sure if you fixed it but this looks good to me after I added Select Objects node I cleaned up your graph and it look really nice, I will use your graph to test out my own workflow.
