Hi Waqar 

Thank you for posting in the Lucid Community To clarify--when importing your Draw.io file dynamic attributes that shapes posses aren't typically recognized when imported into Lucidchart which is why your entities are being interpreted as regular shapes. However we are always looking for ways to improve and this is no exception. I have forwarded this lack of functionality along to our Dev Team for them to take a look at. 

Thanks again for reaching out and making us aware of this gap--firm handshakes
