Building views / drawing / coordinates

I've produced some building views, but I'm having some troubles with coordinates in the resulting drawings.

They simply don't match the original coordinates, which makes it almost impossible to reference BV from different floors onto each other.

Either is this a problem in the BV system, or I've done something which I shouldn't have done.

Any hints?

    BV is invaluable in creating your model.  I use it constantly in creating the  model as it is so much faster than DEM.  I CAN MAKE CHANGES IN THE SECTION THAT AND CAN'T DO THIS IN A DEM.  When using DEM I waste too much time making DEM after DEM after DEM to see if things are correct in the DEM.  With BV's this is gone.

    I ahve switched fully to BV and just recognize some things that have to be fixed.

    In reality how many time do I creat an Isop with all elevation placed on top of that plan.  I've never done one but see them in presentations every now and once.

    The only time it ahs become a pain is when I delete a BV vfom my master model.  I still have an external file with annotations but no BV.  I have to recreate that BV and move it into location since it can move.  (The original BV is located relative to the centroid of the elements viewed.  So if you add something that changes that range like a small element or a large reference file the origen of the BV is changed.

    The work around for the times it becomes an issue is small.  And I hoep Bently listens to fix this.

  • I'm really quite new to BV, so probably I am not understanding the whole concept correctly.

    When you are creating your model, I assume that you are working in the default model, and not in the drawing model.

    What I mean is that the coordinates in the drawing model MUST be correct, as I need to be able to reference axis, or other stuff into it before referencing it into the layout.

    Or is it possible to create your model via the drawing model as well?

  • First I create a reference file for each area of my buildlnig - exterior walls, stairs, roofs, interior 1st floor, 2nd floor, gutters, etc.
    I use this as a tool to make things easier to work with and to also effect speed of drafting

    Then I create a master model that references all files.  Up to thsi point everyting is relative to (0,0,0) or some other origen.  Note than when I craete interior wall I have to first attach teh exterior wall and then draw in relation to that,.  As with each file I make it has files attached to help in making htat file.  So I have everyting related to each.

    The building view are just that :Special views" of the building.  I typically create a drawing view which is nothing more than a separate file with an attached reference of the master model with the "Buidling View" as the view I've used for the way I see that master model.

     I could also just create a building view.  Then create a separate empty file and then attach the model using the BV I just created.  That would be thesame thing .  Bently just created a way to quickedn the steps for creating this Drawing.

    This issue now is that if I reference all my buildign views together they do no come at the location of the cut.  They should.  but the reality is that this is not a strongly needed feature.  Like I mentioned before, how many times have I dont this to creating a working drawing?  NEVER.

    The only issue is if I have to recreate the section it might have changed from the location of the annotations.  I then open my file with the annotation, attach the new BV as my old was deleted by me by mistake, and then move may annotations.   THSI SHOULD NOT BE NECESSARY, but it is workable and does not happen often.

  • Communication with other disciplines?

    How about those of them who still are working in the 2D world? Until now I usually would export the drawing extraction to dwg. As far as I understand that would be the drawing model now.

    Btw.: I would really appreciate if you (or someone else) could post an example file to communities. Regarding documentation Bentley has really improved things with the "Best practice" manuals. But I am missing some example files which we could use to try for ourselves.

  • No - I do this also for my older MS engineers and Autocad Engineers

    For me it is easier to create an externall drawing view as it is closer to the way I working in DEM

    I end up with a drawing for each section, elevation or plan.

    then I just grab each and batch translate

    Hint:  If you ahve to create both V7MS and Acad files.  Translate to V7 files first then those v7 to Acad.  It is quicker
