Timber joists/beams in 2D Views

Hello

I have attached an image, in which you will (hopefully) be able to see some wireframe cross sections of some timber floor joists.

(it's a 2D wireframe referenced in to a 3D model). As you can see, each cross section through the joists is indicated/emphasised with a 'cross'.

How does this get dealt with in BA, when generating a 2D cross section with a DV. As far as I know this type of 'graphic symbol/representation' is pretty much standard (certainly here in the UK IMHO)

It would not seem possible to set/create this 'effect' via the Dataset.

    Appreciate your feedback

    Low priority .............. they need to do some more field research then

    If a basic (very basic .... it's one of the first things you would learn about 'technical drawing,) bog standard graphic convention such as this is not seem as something that should 'just work' .... I'm struggling to find the words .....

    The problem is it isn't as WAD ........... IT SIMPLY DOESN'T WORK!

    There's little point in developing some amazing new 'back referencing' of 2D Drawings in to the 3D models if you are going to have serious difficulties generating those 2D drawings from the 3D models in the first place ..... this will get abandoned and there will be no DV based 2D Views to back-reference in !!!!!!!!

    There are a whole raft of 'rendering modes' being developed, which might sound and look impressive, but do we really need them? Are they a priority ..... certainly not

    We need (as in we are contractually obliged by our clients) to produce 2D Working Drawings (and lots and lots of them) and will have to for many years to come.

    We need to do this in a clean and straight forward manner ...... not fiddling around with custom linestyles in the dataset for something as BASIC as a cut through a piece of timber

    Something I can do in an 'old fashioned' 2D file/model in about 2 seconds!

  • This worked a few years ago but I've been told WAD and Low Priority.

    I've talked to many and few seem to use this as a BIM tool but a BIM modeler

    The modeler should work first then the BIM should follow fairly easily.

    Until centerlines, patterning elevations and sections are fully developed this product cannot claim to generate elevations or sections

    Thanks for your perseverance .... afraid I haven't looked in to it again yet ... been fiddling with DVs mainly

    Glad you made some progress. Having to create a different part doesn't sound too bad as there might be only 3 or different widths of timber beam ... however if you had more cases it would begin to get excessive. You may well eventually want to have separate parts (costing, specifying and so on) .... though these 'parts' might not always just correspond to the breakdown of timber members by width.

    It does ultimately seem to be an unnecessary amount of 'fiddling' and number of steps to accomplish such a thing.

    Such a feature should really be there 'out of the box. The creation of drawings with the required hatching/patterns/graphic symbols should not be presenting such challenges. I can understand having to tamper with the Dataset when getting to more advanced stages of work where you might be looking to 'link' together all sorts of different 'information' about the building (over and above just the visual representation in 2D drawings and 3D rendered images)

    Once again, thanks for that ... I'll keep tabs on it and come back to it at some point

    Regards

  • Danny,

    I worked on this linestyle some more, but can only get the "X" to be variable in length.

    The line style can be adjusted using the scale factor to fit any width lumber.

    To do this however, one needs to have a separate part for each different width.

    Glad you feel this is required. For me, these 'bog standard' features/capabilities need to be sorted out and fully tested/implemented before we attempt to build some 'BIM model' containing information about Fire Ratings, Quantities and Costs, construction sequences, thermal properties, rates of ventilation, ..... and a whole array of information that ..... most people will not contemplate attempting to incorporate if we are still having to 'fiddle about' creating custom cells/linestyles/templates/dataset items in order to deal with what certainly IMHO is a pretty 'standard' part of producing 2D production drawings.

    Really you should just be able to select 'cut timber symbol' as the 'patterning' and it then apply an 'X' of the appropriate size (from corner to corner)
