Can you rotate the project dimensions?

Recommended Posts

I can't find anything in the RW15 Help menu answering this question. My current project is a relatively small site with 34 borings in an area measuring about 350ft x 500ft. However, due to the placement of a building, the borings are in an approximate 'L-shape' when viewed in planview. Further, the site parcel is not oriented north to south.

Does RW15 have a built-in way of 'rotating' the project dimensions to accommodate sites that are not oriented north-south? If not, is it something that can be built in to the next release?

Hi Tom,

RockWorks models are required to have south->north and west->east orthogonal orientation, and thus the project dimensions are so defined. You can clip your models to exclude areas outside the boreholes (say, above your rotated "L") by defining a polygon representing the area you're interested in, and applying a polygon filter to the grids and models to assign those outer nodes a null value.

Once you create a map to your satisfaction, you can export the map to a high resolution raster image, then rotate it as you like in a graphic program to get your "L" shape up-down on the output rather than angled.

There are a variety of tools you can use in RockWorks to define the polygon, such as creating a borehole location map, drawing a polygon over the borehole area (Draw | Line Types | Polygon). Then click on the RockPlot Edit arrow, right-click on the polygon and choose Save to Polygon Table. You can then use this table (now part of the project database) to constrain models, clip grids, etc.
