[@cleudimarneto6149]

Cheers for your videos! I just started using dynamo, and your content is very helpful. Thank you very much

Hi Firas, great tutorial! When i have two points. The point is used to set the family and the second one to set the direction of the rotation,. The goal is that i can set the family and than it rotates towards the second point. There are a lot of these two point pares and they are independent from each other. Thanks :)

[@FirasNoori]

Hi dear, you can re-organize each 2 point by changing the list ordering to allow group of 2 points as one for location and the other for direction

[@Maxfocke]

Hi Firas, many thanks for your reply :)) Which node can I use to rotate the family towards the second point?

[@FirasNoori]

@@Maxfocke hi dear, try using "FamilyInstance.Set Rotation"

Thank you for sharing your skill. It was very clear and well explained but not sure why the curve in revit model does not show in dynamo:(

[@FirasNoori]

Thanks mate, I guess u need a different node to select them or to model them

[@talia8092]

Love your videos, they are so helpful!! I was wondering if there is a way to select a specific point on the plane so that all of the objects along the path rotate to face the point. Thanks!

[@FirasNoori]

Many thanks dear for such kind words, so you are in need to design nodes make a group of objects looking at a specific one point at there centre, coz if you pick a closed circle the nodes I designed will do that? Right ? Or not, if you can send me a sctech of want you want at my email plz

[@dannyrr1]

Great video! I did an array, some chairs on an ellipse, on one side the rotation is perfect, on the other half it gets kind of messy. how can I make them all face center?

[@FirasNoori]

Hi dear, great, can you post a picture of the result, so I can know what's goings-on? My email is [e-mail]

[@1102BE]

hi Firas, great video thanks, do you have a Idea how to solve problem when more than 1 line/curve is selected , in a row - he teaks individual line /curve instead of 1 big, so there is overlapping of the families or there is wrong rotation on some of them.

[@FirasNoori]

Greeting, wishing you the best, to answer your question regarding using more than one curve, simply use "Select Model Elements" instead "Select Model Element" as the first allow the selection of more than ONE curve, then use "Element.Curves" to get the Dynamo geometry curve out of the Revit Element Curve, then used "List.Flatten" to soften the list and prepare it for the joining, then use "PolyCurve.ByJoinedCurves" to make on Polycurve from these fragmented curves, now go ahead and use any division, for example "Curve.PointAtParameter" and you notice that you will have all the curves (or the polycurve) divided not only one, Cheers FN

[@TheHhtiras]

very very nice

[@FirasNoori]

Thanks dear

Any tips for finding the tangents on a polycurve? I have a bunch of model lines joined

Hi Mr. Firas, great video! love it! , I wonder if i can do something a little easier, i need to instance an element over the edges of a regular polygon, is it possible? Thanks a lot!

[@FirasNoori]

Yes it is possible, do u want me to make u a video?

[@jeremiely5053]

hi Firas, so informative video thanks. Q: instead of divide by point, can we do like point every x distance ? thank you

[@FirasNoori]

Thanks, dear for your kind words, to answer your question, you can define almost all types of division methods; i.e Curve.PointAtEqualChordLength or Curve.PointAtSegmentLengthFromPoint or Curve.PointAtChordLengthFromPoint or Curve.PointAtSegmentLength or Curve.PointAtParameter, different methods depend on what you want and how you want, to what type of input u need, if you need it based on chords coz you are filling straight lines not curve, or you want normal curved segment, etc..

[@saribal]

Hi, I followed the above video but was hoping that it could be taken one step further? We want to rotate a family around a curve by using 2 points on the family? Is this possible?

[@FirasNoori]

Hi dear, can you send me a sketch or a picture of the case you need to achieve plz?

[@JayPabs17]

Is there a way to modify the point at which the object/family sits on the curve and a way to define the direction of the tangent?

[@FirasNoori]

Greeting dear Jay, if you want to modify the location of Object/Family on a curve you can simply use "Curve.PointAtParameter" which can specify the location as a percentage (0 =begining and 1=End), the rotation I used the tangent to define it as perpendicular to the curve at all times, but you can "Geometry.Rotate" node to control that manually

[@juancano1906]

Thanks! I have a question, how can I rotate my elements on a desired degree? I mean, my family type follow a path but I write the degree that I want.

[@FirasNoori]

Hi dear, use "FamilyInstance.SetRotation" node, and see this video kzbin.info/www/bejne/imOziKKtjcSeb5o and this one! kzbin.info/www/bejne/f4Orq4Svr6ijgcU Cheers Firas Noori

I have placed families on a path if I want to align the object along the line (Align longer edge of rectangular object to the path of line). Please let me know how to do that.

[@FirasNoori]

I guess that I posted another video to allow the rotation of the element to the path itself here in the channel

[@shashankbagane448]

@@FirasNoori I dont want to rotate. I just want to align it along the path. If I have placed a rectangular solid block along a path and if I want to align its longer edge along the path like I want to touch the longer edge of solid to the path line. How to do that ? Placed families are at the center of path line and I don't want that. I want it be on the either side of the path line. I think You got my point what I expect.

[@FirasNoori]

Aligning is a function inside rotation my dear, anyway, you can use bounding box function to known the lower right And the lower left edge of the box, then move that to the path instead of the center, the array. OR, define the distance between the center of ur object to its lower left edge, and move it prior the array process

Hello Firas, Great video , I just wanted to ask if we can do a path array and specify a specific distance between two families , How can we achieve that? IN other words , we have the path and we have the family I want to do a path array for example on a model line and the distance between each family is 1 Meter . Can that be achieved ? Thanks a lot

[@FirasNoori]

Hi Ahmad, thanks, try to use the one of the following (1. Curve.PointAtEqualChordLength, or 2. Curve.PointAtEqualSegementLength) the first if you want the division to be one chord length as it is the imaginary line connect the equal divided points on the curved path! and this one the chords are not running on the actual origin path! the latter, is using segment, and the divided parts are parts of the curves! and they are also curves not straight chords! cheers mate and all the best 2 ya

This may be a very dumb question, but is there a way to select a "chain of lines" instead of a spline? I am unable to use the tab key if let's say i have several lines that i want to select all at once. The select element only lets me select one line. Great video by the way!!!!
