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.

    Danny,
    I just looked at creating a X-line style.
    It is attached. To get the look in the picture, I just selected it in centerline symbology.
    and toggled off match part width.
    Also set the definition of part to 1 1/2" wide.
    Right now, line style is set to 1 1/2" wide and adjusts to any length.
    Going to look at it further to see if I can get it to be a variable width also.



    Give it a try.

    Thanks for that .... sounds like it might be a novel workaround

    I'll have to brush up on creating linestyles as it's something I'm still a bit fuzzy about.

    Will let you know how I get on. Though about trying something with the Cross Hatching tool, or a cell, but couldn't see how that could be made variable and you would end up having to create a part for each size of timber member

    For now I might have to resort to creating a cell (a simple 'X') at the correct size, say 100 x 225mm and try applying that with a scaling of 1.0. Or maybe applying the Cross Hatching 'Pattern Type' and then and adjusting the 'Pattern Angle' and 'Pattern Distance' as required for that size of timber member.

    Thanks for your input

  • If Bentley would fix the CENTERLINE MATCH WIDTH feature it would work.

    This only worked for one cycle 5 years oir so ago then was never fixed.  It has been logged many times.

    I would love this for all rough cut lumber.

    I would then only need one part that would be drawn and the "X" would fit all

    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)

  • 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.

    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
