2D Length for Railing panel?

[MinhNguyen]

Hi all,

I'm getting started with GDL, so please excuse me foe the dumb question!

To get the 3D length of the railing panel I can use RAILINGPANEL_GEOMETRY to get the coordinates of the points and subtract to get the length. But this one doesn't work in 2D. I tried the same trick with RAIL2D_FULL_POLYGON_GEOM but it doesn't work. Maybe I got lucky and have the 3D one working without thoroughly understand how it behaves. Can someone show me how I can get the panel's length in 2D script?

Thanks a lot in advance!

Hi.

Kindly investigate this.

[MinhNguyen]

Hi, not sure if this is an answer to my question?

[Toper Barrientos]

Hi Minh.

Im sorry for some glare answer.

What i mean is try to open the railing tool.. fr. there, several gdl scripts will open.

Then, go to the macro for 2d, & check the relevant 2d coordinates of the panel length.

Ah, thanks for the info! What I'm trying to build is a custom railing panel from scratch, and I need the panel's length in each segment for calculation. I succeeded with RAILINGPANEL_GEOMETRY in 3D script to get the value, but couldn't find its equivalent in 2D script 😞

I created my own panel once.

If I remember correctly, I just used an existing panel and changed the 3D part of the script to show what I wanted.

I left the 2D script alone as it is just a symbolic representation and I was happy with that.

It will adjust automatically as you adjust the post spacing or segment lengths.

Thanks Barry!

Then maybe I will frame my question differently:

Is there a way to get the length of the panel into 2D script of the panel? Like we put dimensions for the panel on floor plan, but to have the value calculated and useable in GDL (whether its 2D script or Parameters, I just need the numbers out for calculation)

[Barry Kelly]

I haven't tried getting lengths in 2D.

I see there are commands to get info in 3D but not so much in 2D

There is ... RAIL_CONNECTING_POSTS

Something about a proportional value for the position of posts where 1 is the overall length (of I assume the segment).

So maybe you can deduce the panel length from that, but it all sounds a bit difficult.

Hi,

You can't get the 3D length in 2D of the panel object. The projected length can be calculated from RAIL2D_FULL_POLYLINE_GEOM.

For labels there is RAILING_3DLENGTH, but that is the whole railing's length.

In IES individual projected lengths can be listed as Width.

Hi Peter,

That's awesome! I was looking into RAIL2D_FULL_POLYLINE_GEOM but can't figure out how to use it.

If I use RAIL2D_FULL_POLYLINE_GEOM[2][1] - RAIL2D_FULL_POLYLINE_GEOM[1][1] like what I did in the 3D script, unfortunately it doesn't work.

Can you please show me how this command should work?

Thank you so much in advance!
