Dynamo to place blocks along Alignments in Civil 3d

[adamothman167]

Hi everyone,

I’m using Dynamo with Civil 3D to place blocks along a corridor, but I’m facing a problem:

The blocks are being placed far away from the corridor.

I’m using BlockReference.Create, and the positions seem to be off. I suspect the issue is related to how the point coordinates are calculated — maybe they’re not aligned with the corridor’s coordinate system.

Has anyone run into this?

Thanks for any help!

Hi @adamothman167,

I think sharing some more data (screenshots, sample files, etc.) would help.

Check if the contents of the block itself are in the 0,0,0 coordinate, cause if I’m not mistaken the node inserts the Block Reference on the exact coordinates you put in - so it works like a sum of coordinates.

This is my dyn file , can you check it please

i did but it’s not working

Your script seems to be fine, can you share an example file with us in order to test it?

Hola amigo @adamothman167 check if your Block that you try to insert is placed centered in the origin in block editor, that could cause the off of the insertion point, share also your .dwg that have your block definition and Aligment to test if is posible please, you can use Curve.Plan Att parameter or PointAtParameter if your coordinate system doesn’t aligned with the corridor, check this others posts, may be help you!

Hola amigo @kubastan89 buenas. I’ve analized your script, you have 2 main issues. you are working very far from the origin, because a scale topic Dynamo will make weird things graphically, i solve this copying your base polyline and recreating an alternative file based on the default origin. when you try to use solid by loft Dynamo is not able to doit because the turns of the curve they are very agresive, then due to the size of the rectangle being too small and the tightness of the dynamo cur…

curvy block Civil 3D

Hola amigo @edcanonb buenas. youre corridor is a polycurve made of multiples curves of diferent sizes, so you have to: Offset your Polycurve to each side. Get the curves of the Polycurve, Offset these Lines. Ask the start or the end points of these curves. Create a New Polycurve and create Coordinate System at segment length Finally you just instert the block in these Coordinate System (For one of the sides you have to rotate 180 degrees the coordinate system). Is not perfect but is better i …
