Hi,

no, it's not possible. iModelJs is based on EC schema and BIS definitions, whereas DGN is proprietary implementation of Microsoft Compound File format.

It's possible to convert DGN into "BIS based description" using iModel Bridge(s).

With regards,

Hi @wuyw1015,

because the original question was about .dgn support, in my opinion it would be better to ask in a new post, because .dgn is not .imodel, so it's another question / issue.

In my opinion iModel 2 is supported only and older versions (1.5, 1.6) created by MicroStation and other products (as output from DgnDb convertor) are not supported. Based on #5 my assumption is that older imodel formats have to be converted / mapped using iModel Bridge.

@ColinKerr, would you be so kind and to confirm / disprove this? ;-)

With regards,

  Jan

@LabyrinthTechnology thx, are there any suggestions about the new issue new issue ?

ColinKerr commented 5 years ago

iModel.js only supports the iModel 2.0 file format, not versions 1.5 and 1.6.

Both questions are important and we are working on more complete responses, please bear with us.

Thanks! 😄

If I have a wish, a transformation matrix / workflow explanation would be helpful.

Even a "simple" conversion flow DGN > (MicroStation publishing) > i-model > (DgnDB convertor) > DgnDb 1.5 or 1.6 > (Navigator / mobile apps / ...) is not well known.

Next step from DGN / i-model / DgnDb 1.x to iModel 2.0 is a natural question, as well as what SDK and API can be used for individual steps instead of the mentioned tools.

Regards,

Jan

The original question has been answered. This discussion now pertains to data conversion, which falls under #12 (marked as an enhancement).
