Hey guys! How's going? Well, i have a problem with block placement: i need to place a lot of blocks along a extensive polyline but the distance of the block isnt equal and the blocks are differents. I thought in create a list with the block id and distance from the polyline beginning. Using that list as parameter, i'll can place all of the blocks of the list with they distance. Can anyone help me?The list have this layout:BLOCK NAME | DISTANCEB1     |    245B2     |    154B3     |    641B4        |    321Thanks!Much love from Brazil!Wellington

Please look at the TraceCurve utility - maybe it can be used in multiple runs (for each block) or we can customize it for the task you need.https://www.cadforum.cz/cadforum_en/measure-lengths-along-a-curve-points-in-given-distances-tip11625
