Points and Conceptual Mass

[PhilvK]

I arranged some points on grid and connected them with reference lines so I can drag them, only some are drag-able and some are not. What should I look for to correct this please? See below.

You could make the points adaptive then you can drag them without connecting to ref lines. Otherwise, host the point on a ref line's plane using pick host when placing the line.

I don't see the 'Make Adaptive' button when I select the points

My bad, I thought you were using adaptive family.  Conceptual Mass don't have adaptive points.  What is the use of this mass?

[PhilvK]

A tent-like structure.

Make Point Driving (select it and look on Options Bar).

You can do it with either mass or adaptive family.  Keep it as mass and host point on ref line's plane then.

You mean you are doing this to  loft the surface?  Those RPs are meant to drive the lofting?  

...something like this?

[PhilvK]

I thought I'd drag the points which would drag the lines into the shape I want. Not sure about the lofting aspect. I'm real new to doing this if you can't already tell. I've been YouTubing....

Just saw your graphic....yes, that looks like what I am trying to do

Well then, your are going about it wrong.  

Place Points first then use Spline Through Points. Make several rows, then select each row and press Create Form. Activate X-Ray Mode and you'll see and be able to manipulate your Points.

I had already done what you described. My confusion is that some of the points have the little drag gizmo when I select the point, some don't, and I am not sure what that means.

Well, you said you " arranged some points on grid".  You don't do that. You place Points first, select them all (in one row) and use the Spline Through Points tool.  

[PhilvK]

I did do that

Ha! Well maybe you aren't trying to do what I'm describing if that don't work either. Can you post a picture or something to describe what the heck you want the finished product to look like?

Below is from a YouTube video that Alfredo Medina did in 2012. I've been trying to duplicate the process. Again, my biggest part of confusion is what determines which points are drag-able and which are not. I've seen info on points  and normalized curves but am looking for a video that is more basic.

That screenshot of one frame of a video is showing how to manipulate the points of an already created surface.  Have you a surface yet?  I think not.  You need to create one first. Use the method I described above to create it.  Once the surface is created, then you can manipulate the points to shape it however you want. 

You know, there a butt-load of videos out there showing how to do it.    

[barthbradley]

Can't you just post a link to that video?  Seems silly to just post a screen capture of one frame of it.

Those are ref planes.  Draw the planes and host your points on them.
