TNJames 12June 2018: Using V19 of Punch Architectural on latest Windows 10 on Powerhouse "game" technology computer.
The 2D drawings of V19 Punch Architectural are functioning perfectly, including copious annotating, numerous revisions and refinements, and precise 2D zooming to fine tune the size of printouts. This is the case for all 3 floors of my 7614 sq ft design of a large home; also for a separate design of a very big 2800 sq ft garage with four 40-ft-deep stalls and an oversize RV bus stall.
Nothing is lost when V19 locks up every week or three.
Displaying 3D renderings, however, has serious problems, which I believe are tied to a well-hidden table of various elevations, a table that is only visible when one uses "Select All" to highlight all the elements of a 2D "Floor 1" and then clicks on "Set Elevation". However, Punch V19 stops me from revising any data in this table of 20 or so elevations, on those rare occasions when I can display it at all (I can cycle through and read the list however).
Specifics of 3D problem: A strip of 4 rooms that display perfectly well in 2D ONLY appear dropped down 11 feet or so under the slab when displayed in a 3D rendering; this also occurs with two rooms on the 90-degree wall as well. The dropped down rooms are best viewed using a grayscale "Clearview" rendering, where they are always a part of the rendering, moving appropriately as one rotates and maneuvers the 3D view. Using a "Textured Rendering" in color, the rooms dropped down below the basement slab only appear when I click on the rendering, then disappear shortly after, until I click again.
Interestingly, when the chunk of basement floor-1 walls have dropped down in a 3D rendering, the doors and such exposed by the missing section appear perfectly within the house. It is simply a section that is dropped straight down in the 3D rendering, cut out of the remainder of the house, all the remainder of which displays appropriately in 3D.
When one looks carefully at the vertical "Room View" version of a 3D rendering, you can see that the floors of these same rooms are dropped down, yet remain perfectly in their intended lateral place.
Vertical 3D views of the house and garage roofs function as intended, showing shingles, crowns, valleys and shading for all 5 hip roof sections used in my design, the gabled roof over the screen porch, and the gable at the NE corner master bath. Pretty darn good.
The 3D renderings of the garage doors, plus the 3 window walls of this huge garage, all display perfectly, with no below-the-slab problems like occur for about a quarter of the house's daylight basement.
