Further to discussion on curved top windows here are a couple of symbols.

They use the "expendable tool included"  system of which I am obscenely proud...

They are originally made horizontally using several layers and then tilted up. A limitation is the 36 point
slabs but they work pretty well in hide, shade and render and stand pretty close inspection in perspective
and isometric.

They are designed to be installed into vertical polygon wall "skins". The expendable tools outer (blue) and
inner (dark grey) are used to punch the polygons in correct register. If you don't need the inner tool, it does
no harm to stay there. The symbols are entered in plan, snapping to left hand jamb viewed outside. Use
construction lines for this.

Also included is a 2D plan in light cyan and an associated dim in lt magenta. That's right folks, 2D and 3D
at the same time - you thought you needed ZAC for that didn't you? (Cut your own walls tho')

The colours of the components are always the same and exclusive. You can thus separate them out using
SelSets , mask, colour. Even if you cannot see them, you can thus get at the tools, being blue and dark grey.

These symbols are bundled using DCSPRINT. This is the mother of all macros when it comes to symbols.
If you have it you can use it to "unbundle" the symbol to its repective layers. If they don't exist it will create
them for you.

Symbols are in metric, of course, but can be enlarged/reduced to suit. I intend to produce these to Andersen
patterns for sale in the US, eventually.


Here is a curved top window. The images are just straight out of DataCad. I think, on reflection, that it would be better
to just have a pair of lines included in the 2D outline. These can then be skimmed for associated auto dimensions.
(The learning process never stops)


And here is a door to match.
