[Discussion] Drafting 2d annotations for architecture

[paullee]

BTW, when FC font is Null, what fonts would it use ?

On mine it says this "MS Shell Dlg 2

But as you can see when i change the fonts, it doesn't update with the changes.

On my Fedora 31, it is just ' ' when nothing is input - so I have no idea which Font it is using

thanks @onekk, I really understand a lot more of how the FCStd format works

This thread is going really fast and far

Well, that's good!

Regarding "working in 2D". Don't know about you guys, but I really dislike "working in 2D views" like in Revit. This seems to me a gross way to try to make "old-school" architects feel at ease in a 3D application by "faking" that they are working in their favourite old-school CAD program.

I'm really convinced that it's not like this. 2d it's not something old school just because it's 1D less than 3D.
2D it's more conceptual. It's simplified. It's straightforward. It helps to improve the control of the 3d model. I do not think that It's something old fashoned. And I do not think that providing a decent 2d experience has anything to do with trying to mimic some other softwares.
And for 2D I do not mean something far from the 3d space, in a different place, or worse, just an output, but the possibility to work with a 2d view INSIDE the 3d space, and in 3d!

But that's just my opinion. Maybe i'm just living in a https://en.wikipedia.org/wiki/Flatland.

I call our world Flatland, not because we call it so, but to make its nature clearer to you, my happy readers, who are privileged to live in Space.

For now i'm just okay with a working solution that can get any serious work done. So if it's 2D fine, if it's 3D fine, but right now techdraw is not a solution.

I meant changing the font of any darft annotation text or draft dimensions. is that working on your side?

Some more advanced infos, hidden in full view on FCstd document

https://wiki.freecadweb.org/File_Format_FCStd

Maybe this could lead to some advancing.

I'm exeprimenting with squlite3 as an interface to hold many objects, the result seem very good, a test creation of 1000 annotation object and a susquent sql query to retrieve those having a specifical styel associate rougly 300 is almost instant done, the powe of the SQL language could be leveraged on doing complex queries and the single file database produced is easily embeddable in the standard doument file.

plus using json serialization, even tuple could be put in the db field, and maybe even more complex objects, as in the data definition is told that using the type BLOB even binary files such images and so on could be included in the file.

It use the standard python3.x libraries as squlite3 is part of them.

Carlo, this is just chinese to me...

I think we shall aim at being able to handle 10K+ objects per session.

@realthunder, @yorik, is this thing onekk is describing something that make sense to you?

I'm not sure if this is relevant and I do not understand how all this works but the Geopackage format is based on sqlite but has spatial components that may be useful. https://www.geopackage.org/
In QGIS I think it works similarly to what you are trying to do. The file that QGIS uses to store document information is .qgz (zip) file that contains the files that are used for the document. Most importantly a .qgs (xml) file that coordinates all of the other files. Because in GIS these files that are coordinated tend to be stand alone files that live outside of the .qgz file QGIS uses the data from external files such as a geopackage to label features. Often many thousands of features. There is also a .qgd (sqlite) file in the .qgz file that keeps track of labeling overrides that have been made for this particular QGIS document. https://docs.qgis.org/3.10/en/docs/user ... rmats.html

Just dreaming here-
I am interested in being able to coordinate more between QGIS and FreeCAD and if the file format was based on a geopackage this may allow for that connection although sqlite might work too.

Have a quick test - it seems it works

Hello baswein, nice to have you here I've been reading your presentation in community.osarch.org . My compliments for your works, it's really interesting and inspiring.
Thanks for contributing to the discussion... I think we are collecting a lot of interesting ideas and points of view...
