    Here is a txt file with the steps written out and the CSS code to copy, I can't get it to display properly here unfortunately

    Thanks for your amazing videos.
    How can we deal with the lines in common of the walls???

    Unfortunately this is a manual process atm as far as I am aware, Dion is working on it, but at the moment the focus is on the modelling module, the drawing module will have a further update sometime in the future but for now and for myself I edit the final SVG in inkscape when it's all done.
    But these things change quickly so it may soon be a thing of the past

    Thanks for your reply. I imagine that is better focusing on the modelling module than the drawing one 'cause bim is more than a drawing.
    Btw the results are very good.

    Great video again! @Ace for editing the Css files do you think it would be better to use a Text Editor (Notepad++ or similar..)??
    Thanks

    Really nice tutorial! I was clueless on how to edit CSS files and where I could find them.

    Hi there! Appreciate all the work done to show al the custom linework. I tied it out, but im having trouble with the SVG output, the print is still showing the tessellation for the sanitary and annotation the representation.
    Im using V0.0.23.03.04 for the BlenderBIM and blender 3.4.1

    I have tried changing the IFC geometry to show the 2d plan representation, but it still prints the same. Also tried selecting the geometry and clicking update representation in the object data properties tab in blender to no result. Imm not sure what the problems is and would appreciate any help or suggestions.

    Hey @SavyGust27 You've done everything right so far, since that tutorial video there have been a few updates to how representation works
    I am busy updating these resources to work with the new representation but in the mean time:

    EDIT:
    I've update the asset file, use this one and it should look right : ( attached)
    Detail file for Lineweights_update representation 230312.ifc

    If you want to do it manually you can read below

    Fix 1: Door and Window tags,
    You no longer need the door and window tags as separate ifctypes so you can delete them,
    How to apply the fixed tags is to select the text object and go into object properties /ifc object metadata / Ifcproperty sets
    then add a EPset_annotation and type in 'door-tag' to the class, use the same process and use a "square-tag" and this custom symbol file below (symbols with square tag.svg)
    You can see the process here in this video around 9mins 33 seconds:

    Fix 2: the representation for the Ifctypes changed
    so use the Ifc4 AU library (below) as an update to the sanitaryware items
    Load the appropriate types:
    1 Toilet 1 basin 1 shower of your choice
    delete the existing sanitaryware items and place the new ones
    and the door and window types load from an update Ifc demo library (Ifc4 demo library 23.03.12) I have attached below and renamed with the date for clarity
    Load a door type and a window type and change the type of the existing door and windows, if that doesnt work out you can delete the door and windows and re-add them to the model

    Otherwise it shouldn't interfere with your editing on lineweights if that is your only goal then you don't need to change the above,

    Otherwise you can use the version of blenderBim that was used for that tutorial and it should display correctly:
    blenderbim-230125
    You can download it here:

    Hope that helps
