Well - I know - took some time to understand the "why datum planes".jonasb wrote: ↑Mon Jun 28, 2021 7:14 pmThis is basically the what Datum Planes offer you. The problem comes afterwards: when "something" changes, if happen that your plane/tag/name looses its attachment point, or is attached where you don't expect it. For a human it's usually easy to tell what's "the same" surface before and after the change. For the software, it's not.C_h_o_p_i_n wrote: ↑Mon Jun 28, 2021 12:23 pm ... I was wondering, why I can't tag (attach a name to) a surface and tag two edges as "origin" to have a reference to attach any folloing sketches - relaying to this surface - to ...
Also for Software I can imagine a way of keeping track ... if the dataset of an Object(node) not just holds the data defining its place in space but also an fixed "tag" ... or ... by it's managed position in a linked list of datasets ... and also it might be unique due to it's relative position & size an relation to the/an origin.
But of course - in case , a dataset within the linked list or an attachment-point gets deleted - I wouldn't expect the software to guess the attachment points for the subsequent elements in the linked list.
