Hi, it doesn’t build in C++ I don’t remember if that was in a support request or not. We can move to 24.2... yes? |

hasFields is not correct, that's for something else, it should be something in here |

Generate georasterThanks for the project. I would like to use a code snippet to generate a raster as such 
and then attach / embed it (in)to the drawing without storing it externally. Hints appreciated on how to achieve that. |
|
there’s a sample PySamples\PyDb\insertRaster.py |
|
I think it depends on how long you need the object to exist. You can hold the image in memory for the session and draw it with an overrule. Or if you need the image to be saved, attaching a raster. You might ask Bricsys how to apply it to a tin surface. But you can also draw it as an overrule. |

It think it’s because you have incorrect indentation with lt.downgradeOpen() Aslo hasFields is asking if the object has an AcDbField object. It’s not relevant to most things unless your working with Text or MText OpenState is a continuous battle with Arx, .NET and Python. The best way to deal with this in Python is to break out areas like this into their own function, for example you can create a function addLayers, Python will automatically garbage collect LayerTable and LayerTableRecords import traceback

Much appreciated. Works like a charmer. Now I am trying to alter the function to update existing layer colors like this: def updateLayers(db, layers):

clr.setColorIndex(layer[1])
ltr.setColor(clr)
layerMap[layer[0]] = lt.add(ltr)
return layerMapLayer table record is not updated. Cannot find any |

Something like this. def updateLayers(db, layers):

clr = Db.Color()
lt = Db.LayerTable(db.layerTableId())

if lt.has(layer[0]):
ltrid = lt.getAt(layer[0])
ltr = Db.LayerTableRecord(ltrid,Db.OpenMode.kForWrite)
clr.setColorIndex(layer[1])

lt.upgradeOpen()

Geometric vertex dependenciesHow would one create/destroy dependencies betwee two entities through a common vertex (for example a polyline or an alignment? have attached a video for further understanding using BCADs parametric mechanisms.

Do you mean though the BricsCAD constraint API? Or through a persistent reactor? persistent reactor requires a custom object and I probably won’t be able to do this in Python BricsCAD has a constraint API, but I think that requires a mechanical license. I have not wrapped that |

BTW, I’m considering wrapping some of the vertical stuff for BricsCAD, some of the BIM goodies look interesting. |
BCAD independance would be nice, so I'll study your mentioned sample and see whether I dig it. |
Travelling sound lovely. Best would be if Bricsys would open a foundation to support your project in their software for going vertical (just thinking out loud), thus enabling other developers to step in. |

Trim sideloaded DWG by closed polylineLooking to script the following behaviour:
Any assistance for 3. is greatly appreciated. The blocks to be trimmed may be over 100M in size. |
|
3, is pretty difficult. Trim uses AcDbCurve.getSplitCurves, so only objects that derive from curve can be split. Blocks add another layer of complexity as you can’t trim a block, and they can have their own coordinate systems if the reference is scaled or rotated. If the block has only one reference, and the coordinate systems are aligned. Then you can split the curves inside the block. If the block is scaled or rotated, then you will have to transform either the curve, or the boundary to match. Otherwise, you’ll probably have to explode the reference, split the curves, then create new blocks and references to replace them 100G? if by this you mean extraordinarily large files, if BricsCAD can open the files without issue, then you have a chance. If there’s a lot of memory pressure, then breaking the code up is probably a good idea, so items can be garbage collected |
|
Thanks for the hints. Sorry for the size, it's only 100M max. Also I forgot to mention that there are entity types not derived from AcDbCurve in my understanding. Example 1: Example 2: Surfaces, sweeps, solids, hatches... a potpourri. Do you see a way to handle that? |
|
To actually trim the objects, you’d probably have to explode all the objects down until they are curves, the objects would also need to be planar with the boundary. If it’s just for visuals, I would consider using XCLIP or creating a SpatialFilter, I see I have SpatialFilter wrapped, but I’ve only tested Get Clip Boundary |
|
I have used XCLIP so far. I am considering to transmit a partial clipped export. By the looks it seems though too complicated. |

I noticed that @CEXT-Dan's samples concerning multithreading do not use the list data type. I have a suspicion that the list data type is impossible to use in another thread, no matter the case. However, I'd like a second opinion from someone more experienced. |

It works!, though I didn't try nesting yet |
|
Is there a native event listener for xref? I'd like to listen for a status change. It seems that AutoCAD does listen for an xref change, as it gives me a notification whenever I save my changes to a file that I reference in another tab. After searching through the ObjectARX reference, the closest thing I could find was a reactor that could listen for xref subcommands. I might be able to use RxVariableReactor though |

you can also use EditorReactor to monitor sysvars, or attach DbObjectReactors to your xrefs |
|
Ugh, I found a bug in EditorReactor [#228], if it blocks you, grab a copy of the new arx modules on GitHub. |
|
In my tests, I could neither take advantage of Editor Reactor and DbObjectReactors (Granted, I only tested modify and openformodify, but those were the only 2 I thought had a chance of working). Instead of tracking the xref status, I'll just make a event listener for save that once triggered, reloads xrefs. |

Is there any way to run a http server in the Runtime Extension? I tried using threads, but to no avail. |

Did you try this? I have no clue about this kind of stuff though. |
Union to solidsDear all, I am tryint to union solids from block references as follows: for ref_id in ms.objectIds(Db.BlockReference.desc()):
blockref = Db.BlockReference(ref_id)
logger.info("Block reference: %s", blockref)
parts = blockref.explode()
solids = []
for part in parts:
if part.isA() == Db.Solid3d.desc():
solids.append(part)Unfortunately I cannot find a sample to unite the list of solids afterwards. Any hints appreciated. |
|
you would use db = Db.curDb()
solid1 = Db.Solid3d()
solid1.createBox(2,2,2)
solid2 = Db.Solid3d()
solid2.createBox(2,2,2)
solid2.transformBy(Ge.Matrix3d.translation(Ge.Point3d(1,1,1) - Ge.Point3d(0,0,0)))
solid1.booleanOper(Db.BoolOperType.kBoolUnite, solid2)
db.addToModelspace(solid1) |
