I added it to issue #3981. Having expressions here seems extremly sensible, because experimenting with different materials may require to change all ratio values in different places in one go.
ok.

ATM it looks to me like MBMSA is a just a trendy thing. :? May someone provide a model example where it makes sense to use it over other methods ? Thx.
My very first attempt of using MBMSA.
Comments are welcome.


PS: Try modifying data in spreadsheet beginning with length and proportions.

Re: Feature Request: Datum line based on construction line.

... Also, most of the parametric information is in there, which means it's a one stop shop for modifying dimensions, almost no need to revisit body003 in three degrees of arborescence to modify sketch024. It's usually up there in the master sketch. ... What do you think about storing the whole inde...

It is quite common to have more than one master, e.g. you can naturally have one for each of the main planes XY, XZ, YZ.
Ok.
Thank you very much.

Re: Feature Request: Datum line based on construction line.

In a Master Body - Master Sketch approach, you'll end up having a functional skeleton and "construction" lines made in sketcher as normal lines. One of the advantages is that with the master sketch you almost don't have to bother with construction geometry. Normal geometry in there will be construc...

Re: Feature Request: Datum line based on construction line.

BTW, I notice that when creating "Datum line" based on Object's X, the Yaw, Pitch and Roll angles can not have referenced values. I think this is a micro bug. This is not a micro bug, this is a pretty big one. Yaw, pitch and roll are actually Rotation part of AttachmentOffset property. And if you b...

Re: Feature Request: Datum line based on construction line.

No. But maybe you can convince with an example. EDIT :also I doubt it can be implemented in a robust way... ;) Consider the attached file "constructionLine.FCStd". Suppose for example, we want to make a linear pattern of Poket along Line(Edge2)-Construction. It could be very easy to create a datum ...

Feature Request: Datum line based on construction line.

Don't you think that it could be useful to have the chance of creating a datum line from construction line arising in sketcher wb?
