Wall Reference Line & Slab Reference plane location

DNU — Thu, 20 Jul 2023 14:00:51 GMT

Hello
I'm working on a custom label.
I need to know the location of the reference line from a wall (or plane from a slab) so the label is always placed perfectly next to the element.

Is this possible?

In this post the "WALL_REFLINE_OFFSET" is requested at Graphisoft, for now without result?

I created a label for straight walls, where the label is placed directly on top of the walls surface on both sides as 2D-Fill to mark the walls surface..
I had to do a lot of Case distinctions.
I needed the following parameters:
- WALL_DIRECTION

- WALL_FLIPPED

- WALL_POSITION[1]

- WALL_POSITION[2]

Maybe you do not need this if you always want to place on the reference line.

For label positioning use this:

add2 LABEL_POSITION[2][1] + LABEL_POSITION[3][1],
LABEL_POSITION[2][2] + LABEL_POSITION[3][2]

Thanks Joachim for the reply.

The ADD2 LABEL_POSITION... is unfortunately not enough 😞.

I know the struggle with the WALL_DIRECTION and WALL_FLIPPED parameters from a previous label, it worked out eventualy.

Do you compare the WALL_POSITION[1] with the LABEL_POSITION[1][1] to know the offset distance?

Here is a part of my script:

! Position des Etiketts bezogen auf den Ursprung _dict_x = LABEL_ASSOC_ELEM_GEOMETRY.referenceLine2D.contour.edges[1].begPoint.x _dict_y = LABEL_ASSOC_ELEM_GEOMETRY.referenceLine2D.contour.edges[1].begPoint.y ! Position der Wand bezogen auf den Ursprung wall_pos_x = WALL_POSITION[1] wall_pos_y = WALL_POSITION[2] ! Differenzwerte X-Y der Positionen Wand zu Etikett diff_dict_x = (_dict_x - wall_pos_x) diff_dict_y = (_dict_y - wall_pos_y)

I am doing different case distinctions like this:

IF ABS(WALL_DIRECTION - 90) < eps THEN ! S E N K R . U N T E N IF diff_dict_x < 0 THEN diff = diff* (-1) ! ......................... ! IF WALL_FLIPPED = 1 THEN dist_C_value = 0 ELSE dist_C_value = 1 mul2_2_values = -1 mal_wert_value = 1 ENDIF IF ABS(WALL_DIRECTION - 180) < eps THEN ! W A A G. R E C H T S IF diff_dict_y > 0 THEN diff = diff* (-1) ! ......................... ! IF WALL_FLIPPED = 1 THEN dist_C_value = 0 ELSE dist_C_value = - 1 mul2_2_values = 1 mal_wert_value = 1 ENDIF

Thanks Joachim for the help.

I think I can continue my search with this. For the time being I have already been able to create a well-functioning label, not yet with all the desired functionalities, but that is for later when I have / get some time again.
