Polyline Accessories

[Anonymous]

When creating an accessory object I saw that I could select Polyline accessory as a subtype. Does that mean that we can attach those objects to polylines as it is possible with Slabs ? How then ?
Thanks for any help.

No - not direct. You have to make all calculations by Yourself including editable hotspots for manipulating the polyline - edge. The accessories just make the simplest calculations like intersectionpoints of distorted edges, can add one polygon to another and such things - and it is way too complex to use this accessory.

Hi, I created an object the subtype of which is Polyline Accessories. It doesn't make anything. It has some parameters that refer to roofs but it doesn´t behave like roof accessories. How to proceed?

You know this Site?

gdl.graphisoft.com/gdl-docs/gdl-guide/chapter-12-miscellaneous/polygon-operations-extension/

or this in german with an example:

Sure. I have done a lot of work to understand polygon operations extension. It is complex but works reliably. Still I don´t see any relation between polyline accessor and polygon operations... did I miss something?

Maybe i missed something? Thanks for leading me in an other direction.

Just googling I found that

Kind of.

I haven't had the time to dig a lot into this. The easiest way to see it in action is to make sure you have the accessories library loaded, create a polyline (with the polyline tool, not connected/grouped individual lines), select it and apply the polyline accesory object: If I remember correctly, only a footing object is available in the library. Once placed, you can change the polyline nodes and the object will follow accordingly, arcs and all. You can even place it to several selected polylines in one go.

It seems that the subtype will get the polyline node's coordinates, and you can use that to script your object. You could also invoke the accessories command without a selection, and this will allow you to place the object like drawing a polyline, but it'll be static once done.

It could be helpful for some types of objects, specially for FlatLandia (a place where AC likes to hang out), cause I'm guessing that Z elevation would need some more parameters, arrays and scripting to make useful objects.

Best regards.

I have started this, I almost have it working with your original polyline.

When trying it with the delivered 2 GDLs for slabs - and then You alter an edge of the slab to be round, the GDL makes a lot of little straigths out of the round edge.

I think that SenecaDesignLLC's polyline can do that better - smile..

Did You find out which number it starts and ends and a Way to turn off some edges?

One of the accessory for slabs is the floor construction object. The problem with this is - You dont need the whole slab - You need rooms! It should read out roomstamps - not slabs for this. And then it should be aware of the Doors too - to let the Floor-construction flow into the Door on the right side of it.

Seneca - Did You find any documentation for GDL about this accessory?

I simply hate this try and error game which graphisoft is playing with us at this things..

Please Graphisoft - let us know the name of the developer of this accessory - to talk directly to him to gratulate him for his invention and to make suggestions for further versions of it and how we would use it.
