Creating architecture walls from autocad

I am Trying To Make architecture walls From autocad lines ,
How to get the Center line between two lines From Cad Lines So i Can draw the wall at the exact place?

I started with Grouping by parallel and then Group by Distance

I would use the GeniusLoci package
What are you using?

i use it but it draw the wall with the center line even if i make the wall location exterior

i use it but it draw the wall with the center line even if i make the wall location exterior what should i do ?

The less clicks option would be to just create the walls that way, and change the location line in Revit as a last step

if i changed it there is nothing happened i should allign it at the exact place

I don’t understand, if i make that change in REVIT the geometry stays where it is

that is exact what happens with me

So, you need to find out if a line in AutoCad is drawn left to right or right to left.
That’s why center line is better
Better still is to upload your script
If the forum doesn’t let you, use a link to some filesharing platform.
