Label in mirrored hotlink

rav668 — Tue, 14 Sep 2021 07:48:37 GMT

Hello,
I would like to ask if there is a function in gdl to check if hotlink in which the object is located has been mirrored. To be more specific I am using wall labels in modules. Without this function, hotlinks are almost useless.
Best regards,
Rafał.

No, I don't think there is such a function or command in GDL. A Library Part can know whether it itself is mirrored, but there is no command that would give information about the Hotlinked Module file the Library Part is located in.
I looked through the GDL Reference Guide but I have not found anything that could accomplish this.

Thank you for your reply. Unfortunately, I have to label each module manually I suggest Graphisoft creating this function in GDL. It seems very easy to do taking into account the fact, that there is a parameter of hotlink which describes if it is mirrored or not.

SYMB_MIRRORED combines hotlink mirroring and element mirroring. As a result, it doesn't matter if an object is shown via a hotlink or placed directly into the plan.
Do you need only one component of the mirroring?

I have used this in my labels and they work perfectly with hotlinked modules in any position

Kristian,

Can you expand on that? The GDL reference guide under SYMB_MIRRORED says: The mirrored state of a hotlink is not included

Also, I tried using this in a wall label I'm looking at, and it returns 0 regardless of mirrored state.

This is the current result of the label:

Hi Bruce,

I might have overlooked that that you are labelling a wall. Walls don't have a SYMB_MIRRORED state, they use WALL_FLIPPED. This also gets flipped when the hotlink is mirrored.
Also labels don't know which side of the labelled element they are at - I have a feeling that is also missing information you would need. You could try something with LABEL_POSITION and assuming a fixed parallel or perpendicular label orientation. But maybe it is easier to solve with a parameter instead.

Thanks Peter. Yes, I've added a 'Used in Hotlink' parameter. Haven't got the logic working yet, but so far it's promising.

Anybody got a fix for this problem, with the same label or any other one? This is what I get with NCS Wall Label 24. Right is module placed with no mirroring; left is mirrored, with all wall labels flipped making the whole thing unusable.

Hi all, I cant remember exactly how I got it to work and I don't have time to look into it right now but I will play around with it later this week. From memory I used the the wall_direction parameter in conjunction with symb_mirrored.

Sorry @Bruce I didn't see your question earlier, I must have missed the notification some how. I will get a solution for you ASAP as I know I did get it working.

I used a user-set parameter (hotlink_use) combined with the WALL_FLIPPED AC parameter to get the label to behave correctly:

flip = 1
IF hotlink_use & WALL_FLIPPED THEN flip = NOT(flip)

Bruce, could you post that fixed label? I can't understand how that fits into the script, and I don't know whether it is missing lines that should be obvious to anybody but me, or just different parameter or variable names in your label (I would try to fix a USA library label).

I will try to post more info when I have some more time...

So, as stated earlier, what you need to do is add a boolean parameter that the user sets. I have called this "hotlink_use" with the description of "Flip in mirrored hotlink". Default OFF.

With a wall label, you also will probably have a parameter already where the user can choose which side of the wall the label appears. In my part, this is a length parameter is called "flipmark1" (forgive the naming...I inherited the part), and can have a positive or negative value (a hard-coded distance for the label).

In the 2D script, I have a flag variable to use in my ADD2 statements depending on whether the label should be flipped or not. This is named 'flip'. I then run a series of tests to offset the label to the correct side of the wall.

In the below sample script, "hdepth" is the offset Y coordinate of the label.

flip = (flipmark1 >= 0) ! Set flip to 1 or 0

IF hotlink_use & WALL_FLIPPED THEN
flip = NOT(flip) ! Adjust for mirrored hotlinks (selected by user)
ENDIF

flip = flip-1*NOT(flip) ! change 0 and 1 to -1 or 1

hdepth = A*(GLOB_SCALE/100) * flip

ADD2 0, hdepth

There will be more to your script, but this is the fundamentals of the transformations I've used. I hope this has helped.
