This makes lines drawings of views of a Group or Component-Instance ready for use in a CAD program. It is best to use this tool in an uncluttered SKP so that the intersections of entities needed to do the complex geometry calculations are not compromised by other unrelated entities [even if they might be ‘hidden’]. Also place your Component-Instance OR Group with its insert-point at the ORIGIN. If it is not located there then a copy of it is placed there, however, ensure there is nothing else in the vicinity of the ORIGIN, including any ‘misplaced’ Component/Group itself. It’s recommended that you select your component and right-click save_as to process it as an external isolated component if possible. Do NOT try and process a whole building with furnishings and fittings – the amount of data in that collection of things will just ‘kill’ Sketchup!
So, select your Component-Instance OR Group [and nothing else]. Pick ‘CADup’ off the ‘Tools’ menu [or type ‘cadup’ or ‘skad’ in the Ruby Console] If there is not one Component-Instance OR Group selected there is an error- message. Tools > CADup
‘CompoName’ is the Component-Instance-Definition’s name, OR if a Group is selected then the Group’s name [or ‘Group’ if the Group is ‘un-named’]. It runs with information displayed in the Status Bar and the view refreshed after each step [v7+ only].
It creates a new Component called ‘CompoName[SKAD]’ on layer ‘SKAD’. If that name is already used it’s incremented with a #1, #2… suffix… Within that it makes a temporary grouped and exploded version of the selected Component/Group located on the ORIGIN. At the end this temporary group is erased and the selected Component/Group is replaced where it was. It has a flat 3d-text label which reads ‘3D’ on layer ‘SKAD.TEXT’ [it’s name is ‘TEXT’].
It then creates the 6 flat 2D orthogonal views of the Component/Group within the ‘CompoName[SKAD]’, in turn: they are named:
[Equivalent to the Plan and Reflected-Plan, and the South, North, East and West Elevations respectively]
These are each grouped and named ‘SKAD-TOP’, ‘SKAD-BOTTOM’ etc [each is on Layer0].
A collection of 6 Sections is added – similar to the ‘view’ but with it cutting the selected object at its center and having an additional grouped set of lines ‘SECT’. The are name after the direction of the section-view not like the views them selves – so the view ‘TOP’ shows the top looking down but the ‘SECT-TOP’ shows the underside of the top looking up. The SECTions are named:-
[Equivalent to the Internal-Plan and True-Ceiling-Plan, and the Sections looking South, North, East and West respectively]
These are grouped/layered etc in a similar way to the ‘views’
A collection of the 4 flattened AXOnometric views is added. They do not show hidden lines or separate circles, but are otherwise similar to the ‘views’. Each is dimensionally correct in the Y and lines that are at 45 degrees to the main axes. The AXOnometrics are named:
You can of course edit the separate view-group parts – e.g. erasing some lines etc that you think are not needed.
