It takes BaW 24 seconds to make a REALLY big mesh (3 Million tris on an area 512x128x512)
as a BINARY STL its 150MB and there is nothing you can do about that, as an AMF (which is basically a zipped XML) its only 19.6MB (despite the fact its a whopping 368mb uncompressed XML).
When you load it into Cura it will take about 3 minutes to show up.
Then it will take about 8 minutes for Cura to figure out how to fill the model in Ulti-quality (bear in mind that its a large model requiring a lot of slicing and paths to fill -> 195.2mm X 195.2mm X 69.0 mm)
One thing which is very annoying is that when you move or scale the model it becomes totally unresponsive (they need to learn about drawing meshes with Transform Matrices).
Probably because they need to transform every vertex on CPU and save it for the slicing algorithm.
Which leads to a funny situation when even if you have instancing/constellations, it still recalculates the gCode fills for each instance (something which they havent thought to optimize yet, I guess).
In the screenshots of the 3D printing preview there is one green arrow and two blue arrows.
Might be a mistake since normally for coordinate axis there would be one green, one blue and one red arrow.
The only way you can move the model is in the 2D plane, you cant move it up or down (as then it would be floating-off the printer bed).
Furthermore the print preview can be improved:
Please allow the arrows to show where the axis positive side is, no two way, symmetrical arrows please.
Please allow for showing multiple arrows for exporting (one set of arrows showing BAW's internal coordinate convention other set of arrows for the formats convention, multiple sets of arrows for multiple formats allow with a dropdown menu in the preview instead of determined by export format)
The screenshots of the 3d models are from the respective printer softwares, its not inside BaW!
We chose to stream mesh data from Multiple OpenGL Contexts in many threads and do the other things, not because they are easy, but because they are hard! - JFK
