Properties GDL

Anonymous — Wed, 24 May 2023 10:43:11 GMT

Hi, I'm trying to write a property GDL that makes the 2D drawing of windows and doors. It will (hopefully) design the elevation with the floor lines (so I can measure the sill height), but I'm stuck at this code:

! draw the elevation
drawing3 -3,90,2
!subtracts the sill height to go to the floor position
add2 0,-WIDO_SILL_HEIGHT
! Draw the first floor line
pen 1
line2 -WIDO_N_RSIDE_WIDTH/2,0,WIDO_N_RSIDE_WIDTH/2,0
! Draw the second floor line
add2 0,-.05
pen 6
line2 -WIDO_N_RSIDE_WIDTH/2,0,WIDO_N_RSIDE_WIDTH/2,0
add2 0,-.1
! Draw the third floor line
pen 6
line2 -WIDO_N_RSIDE_WIDTH/2,0,WIDO_N_RSIDE_WIDTH/2,0
pen 1
del top

Problem: it doesn't acquire the width of the window/door. What am I doing wrong?

I haven't used the property scripts in ages, but can't it read the window parameters directly?

Well I thought so, and it really works with the sill value, but it doesn't with the width. That's the problem here. I think my problem is about the width value of the doors and windows,

Can you post a sketch of exactly what are you trying to do?
A couple of years ago I wanted to do something similar but didn't due to lack of time.
I wanted to create a side elevation of a Door/Window fully complete with dimensions and stuff (of course the Dimensions would be created from lines and texts).

It's exactly what you've described. I want to create a list with the code, number of items, the elevation, plan representation, Cut representation and perspective. My idea is to put it all on a layout, put a independent detail over and put information, details and specifications on it. I first wanted to insert the list directly in the detail, but it doesn't work.

OK, I see.
Back to your original question: since you are on uncharted territory, unfortunately I would not be surprised if it turned out that some Global Variables return incorrect values or do not work. But this you will have to figure out. Sorry to say that.

I verified and it really doesn't return the correct values!!!! I put a text on the 2D code and it returns me a null value. It works for height and sill height but not to width!!!

Finally found out! the parameter I needed was SYMB_A_SIZE. It gives-me the value I need! Now the next problem : I need a section of the window/door and not a side elevation. How can I have a section of a object in GDL?

Here is my result

I think that SYMB_A_SIZE is the same as 'A' and the height is 'B' -
I have similar project and just used these.

To get the section you could cut the object with CUTPLANE or similar. Use GLOB_CONTEXT=6 | GLOB_CONTEXT=46 in the main object 3D-code to cut only when listing.

Hope this helps.

Yes, I am also curious about the result.
The only thing that I do not know is how to get both a side view and a cut section view in the same list. If you have the GLOB_CONTEXT then it will be only either one: it will either cut the model or it won't.

I just thought of a possible way: maybe you could duplicate the element so that there would the two instances of the same Door/Window (only when listing) and one of them would be cut by a CUTPLANE. This way you could have a front view and a cut section view in the same list. I hope I expressed myself well enough and what I am writing makes sense to you guys.

Hello,

In the property object 2D-code you have the DRAWING3 multiple times and cut the main object when needed. I used a free users' global S_ to tell the main object which loop is going on.

Fox example;

!--------------------------------property object 2D-code
for xx=1 to 2
S_=xx
drawing3 3, 270, 2
add2 2*a, 0
next xx
del 2
!--------------------------------

!--------------------------------main object 3D-code
!--this must be in the beginning
if (GLOB_CONTEXT=6 | GLOB_CONTEXT=46) & S_=2 then
addz 1
cutplane
del 1
endif

....all your cutted 3D-code here...

!--ending the cut
if (GLOB_CONTEXT=6 | GLOB_CONTEXT=46) & S_=2 then cutend

!---------------------------------

Hope this helps.

Just a little problem. I'm not changing the object 3d Code (I would have to change all codes of every window and door I have - and the coming ones). So I have to make alterations only at the property code, which belongs to my system.
Probably I'll have to discharge the section on the list.

If you do not change the 3D Script, then I do not have any idea of how you are going to have a cut and a non-cut version of the same element in the same list.
Maybe you come up with something extraordinary, but I do not have any other idea at the moment.
