We require manipulation of a 3D solid for presentation in a static 2D (isometric) representation. This is for a location awareness package, onto which various assets will be placed such as access points, and then personnel and equipment movement will be represented in the software package.
Technical Requirements – Location Awareness Maps
For each mine, several isometric maps will be required, splitting the mine into three or more portions (upper, middle, lower for example). At Mine 1, for instance, each portion will consist of four or five levels. The base map will come from a solid-model export from our mine planning software. The original orientation of the derived Location Awareness maps should come from the life-of-mine design so that future changes in orientation are avoided. Further maps can be added if the mine goes deeper, or extends beyond the contemplated design.
Each of the Location Awareness maps must be formed of polylines in AutoCAD that only show the outline of the void at the mid-height of the opening i.e. 2m above the floor level. Alternate levels will be different colors to make visualization easier. Each level will require a label – at another site where Location Awareness is implemented, this Level Name is drawn rather than a text box. (I will attach an example when I can grab one, a screenshot for instance of the before and after states).
Some degree of vertical exaggeration will be required to ensure that levels have minimal overlap. There may be a requirement to artificially ‘extend’ the mine to avoid overlap, by lengthening drives/ramps, for instance.
When each new updated view of the mine is produced, it will have to be from the same location, with seven degrees of freedom locked:
1) X coordinate of camera
2) Y coordinate of camera
3) Z coordinate of camera
7) Zoom level
The locking is required so that when the updated drawing is imported into Location Awareness, other assets such as Access Points align correctly. Hence the need to have the original setup based on life-of-mine design.
Updates will be required approximately each 2-3 months, to include new development meters/voids. These will be exported as DWG file for import to Location Awareness. The file type saved prior to importing it in Location Awareness should be DXF, Autocad version 2010. This procedure will replace the current update cycle that the outdated system requires, which only produces a long-section view.
Freelancer and myself will need a long discussion ahead of awarding the bid, to develop SoW, etc. Freelancer will be required to sign a corporate NDA.
