how to create holes within a "hatch/pattern/flood/etc"

Good day everyone

What would be the most practical way to create a hole, in a hatch?

Advice is appreciated

thank you

Win 10

Microstation v8i - SS4

( I like to be able to see what I am snapping to )

  • Hi Jeffrey,

    at first, thanks for the video, it makes the situation clearer a bit (even when to capture the whole MicroStation application windows would be better). My feeling from the video is that there exist a lack of knowledge of MicroStation tools and how they work.

    I would like to be able to draw complete shapes

    I assume you mean "shapes" not in MicroStation terminology (shape element), but in more abstract meaning (a drawing of specific object).

    and by using the "Bring to Front" function

    Do not use it!

    This function is very old and treated as obsolete, because based on order of elements in design file (which is roughly equal to an order how the elements are drawn). The problem is that the order ca be changed anytime, when an element is modified and has to be moved to the end of the file, which is often out from a user control.

    stack shapes on top of each other

    As wrote, to use Element priority is what should be used.

    I am able to do it in AutoCAD using a "Draw Order Layer" function

    Even when Draw Order Layer feature in AutoCAD brings many benefits, in fact it's a result that AutoCAD is not able to handle 2D files, whereas MicroStation is strictly "geometry based" tool (and Draw Order Layer disrupt 3D concepts).

    but I believe the version I am using of Bentley is not as flexible as newer versions may be.

    Even when you are using old MicroStation version (SS4 was released 4 years ago, but V8i generation was introduced 12 years ago!), the main concepts has remained the same also in the current CONNECT Edition generation.

    In my opinion more problems are caused by a fact you are trying to use MicroStation in AutoCAD style, which often leads to confusion always, because they are different: Some things can be done easier in AutoCAD, others in MicroStation.

    I may have to completely change my approach to achieve what I am trying to do, and I certainly welcome any advice anyone is willing to share.

    A broader context is not known (where original data come from, what is expected result...), but typically these drawing are generated as views or sections from 3D models, so the most of "hiding" is done automatically when visible edges are calculated. The dynamic result is consequently annotated in drawing model.

    There is no such information available (the best option would be to use more specialized tool like AECOsim Building Designer, that offers more specialized, not general CAD, functionality), so I have to start with the assumption you create the drawing from scratch.

    It's all about the model structure, otherwise no tool can help you.

    I think it should be something like:

    • The model has to be 2D.
    • Shape + holes grouped together and filled using Create Region tool.
      The same result can be achieved using Group Hole tool and changing fill parameters of the created cell.
    • Everything, what is displayed on top of the basic "shape" (technically it's probably a cell), has to be in separate layer with assigned higher priority. It ensures it will be displayed always on top.

    With regards,
