 Hi, Michael it is possible to orientate a perpendicular object to a surface on intersection ? Thanks Image Attachments:

 1543.2 In reply to 1543.1 Hi Marco, for a general surface this will be difficult because there isn't any method to create a surface normal from a general surface right now. But it looks like you may have a cylinder surface there? In that case it is possible to create a surface normal by drawing a line from the central axis line. Once you have a surface normal line as a target, it is possible to use a combination of Transform/Move and Transform/Rotate (or possibly Rotate Axis) to orient the object. Here is an example for how to do that: To orient this cylinder to this line, start by selecting the cylinder and running Transform/Move. Pick the base of the cylinder as the start point of the move: Pick the surface intersection point as the end point of the move: Then to rotate into place, in this example it can be done by doing a 2D rotate from the Front view. Pick the center of the rotation at the intersection point, and the base angle point at the top of the cylinder: Then pick the last angle point at the end of the normal line: This will orient the cylinder in a perpendicular manner: I definitely want to add some orientation tools to make this easier to do though. For version 1.0 though you have to use moving and rotating as individual steps. - Michael

 1543.4 In reply to 1543.3 Hi Marco - for placing many items like you show there, instead of using the "Move" command, use Transform/Copy instead. While Transform/Move will end after picking one target point, Transform/Copy will instead let you continue to place another copy for every target point that you click, so click one target point at each of those intersections to place a copy there. Then I think you can select a row of those bristles, and then use Transform/Rotate on a row at a time to angle them off to the side like I showed above there. Please let me know if you need a more detailed explanation. - Michael
