Is there a possibility to ad a section profile to a window?
standard there rectangle - top-bottom and sides have ussally differend profyle's.

and is there a possibility to have differend levels of detail options?
or is this an option for new update?


  • Frankly, I don't think this is something Bricsys should be bothered with.

    There are already enough applications available that try to cater for the exact needs of their customers in all varieties of markets, and this IMO leads to bloated and in the end unmanageable software.

    I partly work with such a fossil (ArchiCAD): Gigabytes of provided objects, some of them with hundreds of parameters - you can spend hours checking them out, and in the end you still don't find exactly what you were looking for.

    A versatile CAD system should not force you to content yourself with the given, but rather empower you - the educated user - to create anything you wish. BricsCAD so far mostly followed that line, and I hope they will stick to this. You should therefore not expect the provided window and door objects to cover all your needs, but rather see them as examples and a starting point to create your own.

    In the attached example, I took the provided "Window_1x1.dwg" and edited it a bit according to what you asked for:
    - added a parameter "FrameThicknessBottom"
    - pointed the constraint for the bottom frame thickness (Distance_39) to this parameter
    - added a profile, and constrained most of its faces to stick to the window frame
    - added two distance constraints to keep the front and back face height constant
    - added a distance constraint so that the sill will protrude 20mm from the wall surface.

    If you are familiar with constraints as a concept, such modifications will only take minutes. However, if the complexity of the model increases, full parametrization may turn into a nightmare. I think that parametric objects should rather be kept simple, and that it makes more sense to replace them with static objects if you need full detail.

    I second Knut's statement.
    Bricscad should offer some simple nice parametrical Objects
    (there are still missing a few like railings, stairs, ...)
    that fit a low LOD of 1:100 - 1:50 drawings.

    From there, like for Doors and Windows, you have the freedom
    to add any detail or create your completely custom Objects
    solutions as much as you like. Not limited by the typical Plugin
    Object Toolsets you see in some other packages, which won't
    reflect our special wishes and needs most times anyway.

    And that's where it gets even better in Bricscad with all new tools
    like "Parametrize" that will support you when creating complex
    individual designs without limiting freedom.

  • have you looked into the use of the BRX_2D+ layers? bimpatch might also be an option, as long as its only a few details to show the exact window installation. i would avoid increasing the complexity of the parametric windows, i've had performance problems and some weird behaviours (parametrics not updating correctly) trying to make things too fancy..

    It is not possible directly from the given Insertion Objects.
    But as those are just Blocks including a clip volume,
    dumb or more parametric, you could edit or replace the offered
    Blocks by any custom Block you need.

    and is there a possibility to have differend levels of detail options? or is this an option for new update?

    Currently there isn't.
    A workaround would be by Layer separation and Visibilities.
    That could easily get complicated and cumbersome though.
    Or by creating extra companion Detail Blocks that you lay over your
    low res Insertion Objects (?)

    So beside only Layers alone to control which parts are activated and
    which aren't, such parallel Overlay States like Level of Detail
    (Or Structural vs Non-Structural, Stories, HVAC vs Architectural, ...)
    would be very nice to have.
    To have easier control over Visibilities in Model and Layouts.

  • LOD is ideally suited to AI I'd a thought - of which Brics is a leading light. Looking forward to it.

    I am not sure how AI can help with the LOD of windows.
    But it is relatively easy to create a window with more details if the cross section of each member of the frame is fixed. You can then apply a Rigid Set constraint to each of them. See the attached example.

  • LOD must be more than a mere rule-set about which elements to display, which complicated shapes to simplify etc, simply dependent on screen zoom or viewport scale.

    Well, it can be that as a first implimentation, but AI aka machine learning can learn the preferences and style of each user, or 'house style', and offer a much more subtle LOD presentation, requiring less tweaking, per user.

  • @Tom Foster:
    Your last suggestion requires at least 3 major steps:

    1. Digital content with a high LOD for BricsCAD BIM. Some of that content will have to comply with local traditions and standards. In the Netherlands we have our own standards for wooden window frames for example.
    2. Code that takes a high LOD object and generates a lower LOD representation on the fly.
    3. Code (AI) that somehow 'reads the user's mind' and uses that information to customize step #2.

    Would probably require a fat computer as well. And I wonder where the user data of step #3 should be stored. You would not want to lose it in case of a computer crash.

  • Agreed - and step 3 is exactly the wonder that AI promises to achieve.

    It does not (yet?) directly 'read the user's mind' but it sees what the user does over many sessions, notes repeated patterns, compares that with the 'meaning' of numerous others' patterns, and thereby thinks it knows what the preferences of this user will be in many situations.

    It's in principle what Google, FB and Amazon do, which is very scary because they do it as 'surveillance capitalism' aimed at automating us plebs for the benefit of elites

    The challenge is for society to put a stop to that kind of use of AI/machine learning before it's too late, so its benefits can be offered as freedoms to the world.

    Oh, and 'fat computers' - no problem, plentiful on 'the cloud' - but that again is presently something that plays into the above plot and has to be tamed.

    Hi all,

    I think low, medium & high levels of details for any component in plan or section views would be useful. i.e. low for planning type drawings & high for construction drawings. I think this may demonstrate this, albeit in another CAD programme.

    Over & out,

    Having to generate a typical floor plan on 8 storey refurb. project in Auckland and we are a bit ahead of the architect before modelling HVAC ductwork/pipework. Been on site and measured up beams etc and initially had no problem putting in full height glazing to atrium but now I'm finding even though the properties box of components allows me enter new values for window re height/width, it does not change actual 1X1 window size in model. I presume I have inadvertently changed a 3d constraints parameter. Tried with new drawing and same result which is strange. Forgot to thank Louis last week for prompt reply to last query too.
    Really enjoying time savings created by V19 over V18 for ductwork and pipework once I figured out how to use it, especially bimdrag with flow connect and multislice to create duct lengths while still connected which allow set up/down to be modelled to find alternative routes around other services.

    Windows are Blocks - referenced from another (Library) File.
    These Referenced Blocks can somehow be brought into and saved in the current file.
    So you could edit or exchange these Blocks for an inserted Window.

    If you insert a Window it will use the Referenced Library Block to
    create that Window as an "Anonymous" Block.
    (Again just called "Referenced Block" in Bricscad ?)
    This is because you may want to be able to use different sizes for your Windows.
    With a normal Block you would change all your instanced Block Copies at once.

    But you can select and edit more than one Window at a time from Property Panel.

    How to select ?
    Select Similar constraint options in Bricscad, for me were always on the restricted side.
    I think the Structure Panel is the new Select Similar.
    You can add Sizes to your custom search and order in Structure Tree.
    So you should be able to find all Windows with 2,20 m heights that should now get 2,40 m.

  • @muzznrae
    From your description I conclude that the issue is related to the '1x1' window file.
    It seems unlikely that you have accidentally modified it. Perhaps you have never used it before. You can try opening the file and comparing the parameter names against a different window file that does not show this issue.

    Thanks for reply. I thought post hadnt gone thru as it said I didnt have permission to add pdf?
    I had previously used 1x1 for centre atrium windows 3600h ard 750w by editing height and width and depth, even teaking same window for two smaller ones on each end. Then when I went back into model, properties box allowed me to edit dims but did not change window.
    Since then I have tried several times to insert 1x1 and edit on insert without success, only 1x1 inserts. As I said before I even tried with clean sheet but still no success.
    I opened previous model just now and It did allow me to insert/edit to 727x1825. Tyven tried again and no luck. Seems random
