when mdlElmdscr_areIdenticalToTolerance can return a true? does the api works?

You're telling MicroStation to compare two elements, ignoring the mesh sibling ord

ering.  However, each element has a unique Element ID: they are guaranteed to be different in two different elements.  Add COMPAREOPT_IGNORE_IDS to your options:

bool isSame = mdlElmdscr_areIdenticalToTolerance(preEle, curEle, 
    COMPAREOPT_IGNORE_UNORDEREDSIBLINGORDER | COMPAREOPT_IGNORE_IDS, 
    0.1, 0.1);

Hi Jon Jon Summers

this doest work for my first model, did u get this api work? in my case, i assume it will return true, but always return false. i have use the options as you suggested.

thanks,

Rick

Yes.  However, the elements I was comparing did not include the meshes that you are testing.

can u share with me your model where u campare the two elements. just leave two elements that identical. thanks,

I just want to make sure this api works in some scenary. thanks for all u replies.

I suggest that you create a very simple DGN model.  Draw one simple primitive element that is easy to analyse: for example, a rectangle.  Now make a copy of that shape element.  Run your code using those two shapes as the input.

Does that produce the result you expect?  If not, post the DGN file here along with your code.  If it does work, create a new model and add a more complex component; make a copy, and run your code again.  Wash and repeat.

sure, i will try, and by the way, how to paste the shape element to the same location as the original shape element?

1. Start MicroStation's Copy Element tool.
2. After you pick the element to copy, you will see the copy stuck to your cursor
3. MicroStation prompts you for a data point to place the copy
4. Don't click the mouse!
5. In MicroStation's key-in window, type dx=0
   (delta X = zero)
6. MicroStation places the copy at zero offset from the original element

thanks Jon, with the copied ones, the api works, in my case, the offset is not zero, but i transform the two elements to the same position, still return false in my case. might be need to set different option flags.

thanks,

Hi Rick cheng,

If you can you provide a "test case" (simple, portable clearly showing the exact issue) we can work with that.  If a portable test case is not provided too much guess work and assumptions are likely to be made vs. having the Exact minimal source code and data to reproduce a problem and make proper recommendations for.  If you provide a simplified test case we can start to review it as soon as possible.

Thank you,
Bob

thanks for the reply, now after change the options to standard ignore flags, my case pass the identical check, thanks all for u input.
