Hi All,
I know this has been discussed many times but i still can’t find solution to my problem. Im currently reading points from excel to place family instances in revit, so tried graph below but both options is not working properly. Any ideas? i attached also files below for reference. Thanks in advance.
extract the points from your existing revit file from families you create with one point (furniture, doors whatever) and store those points in excel
now make new family instances from this excel file
see what happens
i guess that they will be off
somehow the coordinates system you are using (which is 0,0,0 in an new file and horizontal/vertical and the standard Dynamo uses) is shifted or rotated by this new shared coordinate system.
you need to transform the coordinates to the shift and rotation in your file so they match again.
Mind you that if you want to use this method on projects that are rotated to true north, then you need to rotate the coordinate system aswell.
Take a look at @Daniel_Woodcock1’s description in post 3 in this thread, where he explains the proces. This might also clear up some confusion surrounding this topic
