TD struggles with some architectural drawings. Some of this is due to TD's original use case of producing mechanical drawings of individual parts with hidden lines. The Hidden Line Removal algorithms are single threaded and bog down in cases where there are lots of edges and faces to process.
We really need a feature that just draws the visible faces and their boundary edges.
As @chrisb said, if you turn KeepUpdated off in preferences TD will not slow down your 3D work.
You can also use the CoarseView option on Views. This uses a much faster HLR algorithm, but only returns short line segments, so it isn't much use for dimensioning. Good for initial rough work, though.
Is there away to have multi threaded hidden lines removal or is that an OCC feature?
Yep, definitely sounds right, it would be a good feautre to have to draw only the visible boundary edges
I do use keepupdated off, but the trouble is, when i turn it on, it still takes a very long time to generate a 3d hidden line view. I should clarify that even thought it is a 3d axon section, i've drawn it as a chunk, so i am creating a 3d view of the whole model, not with the arch section tool. Not even sure if the arch section tool could be used to position a 3d model cut on a sheet?
Didn't know about the coarse view option, thanks, will have a look at it

We could make a "fast section" function that only draws the cut face if that is useful.
Usually, it's nice to see a section with elements behind, but for error checking modeling purposes, it would be a nice option to have, especially if it is much faster.

Personally I would like to see two things, custom 3d views of the model and additional stand alone 2d documents that would be saved in the same FCStd file. This are two different strategies, first one is more the way revit views work, the second one is more like how archicad views work, in the long term it would IMO be best to have both. I can go in to more details if there is interest for this...
Definitely a lot of interest in this. There should indded be a way to save and recall views and have an easy multi-view environment. I know how the revit workflow works, but how does archicad work? What are the advantages of having stand alone 2d documents save in a seperate file? I presume the what they are showing is pronbably linked in some smarter way back to the model and the cut in which it is created?
How do you guys work on a project with, say 20, 30 + sheets? Is it feasible yet in Freecad with the current TD speeds?
