  1. Hi Molly, thanks a lot for the hints. I took the sample table you suggested from the samples directory and it gave me the answer i looked for. I defined a color column, binning the depths (in Excel) and assigned a color for each depth bin, which i took as setting in the symbol options et voilĂ ! After then i put the sattelite picture as background and got a wonderful earthquake map. Will also try your suggestion regarding the table-based mapping option. Thanks again! Regards, Cristian
  2. Hello everybody, i try to plot earthquake data with RW 15. The table contains easting-northing-magnitude-depth data. Te map shall show the epicenters (X/Y) coordinates, the radius of the circle the magnitude and the color the depth. So i use EZ-maps and tick only borders and symbols. Now i set symbols/circles, Dimension: variable, Data Column=magnitude, Range 3 to 7. If i set Color=variable, Color column=depth, i get nothing. If i set Color=monochrome, i get my map, but the circles are too big. The setting scaling/linear appears not to influence the diameter of the circles. What am i doing wrong? Thanks and best regards, Cristian
  3. How import topographic lines in to rockworks?

    Thanks a lot Tom! I followed your instruction with the dxf2xyz and it works. From DXF2XYZ, i delete the commas and then replace the points with commas. Direct import makes some problems, but import through Utilities Sheet - although slow- works. Indeed, it is a large valley and the "no-contour" area is the water surface of the river. i received some bathymetric survey so i could complete the data and the topo is "in". The hard part is now to model a band of rock, striking from SW to NE. Sorry for the inaccuracy, the data i enter in the i-data tab are xxE-6 or xxE-7, which are displayed as zero. Tab key works good, i make extensive use of it. Is it possible to open the drop-down list, say in the lithology or stratigraphy units tab with the keyboard? When i reach it and hit Enter, the field background turns white, but i cannot enter nothing. I have to click on the arrow to open the drop-down list and then using the first letter of the items, i can enter them easily. Best regards, Chris
  4. How import topographic lines in to rockworks?

    Hi Tom, Thanks a lot for the reply. I uploaded the xlsx and the dxf zipped file on the upload page. The point is that i use a german WinXP, with german locales, so decimal point is comma. That means, if i export from RW to Excel, comma values are interpreted by Excel as text. Coming back to the the navigation issue, my workaround is to "edit as spreadsheet" in RW and copy and paste from Excel into it. Works fine. What i meant by keyboard navigation is for example, creating a new borehole and subsequntly enter some data in the other tables, such as stratigraphy. Then i want to create a new borehole and for this i have to click with the mouse. I miss here a keyboard shortcut - or perhaps i didn't found it out yet. Best regards, Chris
  5. How import topographic lines in to rockworks?

    Sorry, gentlemen, the problem becomes actual again. I tried to upload the filtered DXF (only contour lines), but it is some 700 kB zipped and the system does not accept it for upload. Now there is another issue: i have a lot of permeability data calculated from Lefranc tests, given in cm/s. The values are some 4.5E-4 or similar. If i enter it to the i-data table, i see only zero values. Is there a way to format the columns in the borehole manager to scientific? By the way, i found it better to input the data via Excel, because the navigation through the fields in RW is really poor. One have to switch permanently from keyboard to mouse (i like to use only the keyboard as much as possible, with a lot of shortcut keys=higher ergonomy, quick data input).
  6. How import topographic lines in to rockworks?

    Hi everybody, - i'm using RW15 on a german WinXP. When i try to import the surface countour lines from DXF file, i get some bullshit in the xyz file, see attachement. E.g. in the first row, only the first 6 digits represent the easting coordinate of the point. Is there a fix for this? I tried a workaround, extracting point coordinates from DXF to XYZ, the import them to Excel ant then to RW. - Unfortunately, the suface generated by RW does not match the real surface (there is a large river valley with some islands in the river). I tried all algorithms. any clue? Thanks a lot and greetings from Germany Cristian Test 01.txt
  7. Hi everybody, i think this could be of interest for other people as well. I have to plan a powerhouse cavern for an hydroelectric project. In the area i have only 5(!, spaced hundreds of meters) core drillings, but a more or less detailed gelogical surface mapping. When i use the stratigraphy model from the wells, RockWorks calculates the top surfaces very nicely. But the powerhouse cavern is located BELOW the end depth of the wells and OUTSIDE the area delimited by the wells. The stratigraphy is quite simple, i have metamorphic bedrock (in which the cavern is located), covered by alluvial soil. Surface topographic data are available as DXF. My question is if i can define some "fake" boreholes, say 1 meter deep in spots where the bedrock outcrops, to give RockWorks more control points to interpolate the bedrock surface? Further, if i do so, what method shall i use to calculate the top surface of bedrock? Additionally, there is a fault in the area, delimiting the contact of the metamorphic rock to an granite batholite, which i would like to model in same way, by fake boreholes, is it possible? Thanks a lot and wish you a nice day! Cristian
  8. Hi all, I'm working on a construction project with two kind of rocks (amphibolite and schist) having several weathering degrees. The weathering is modeled by lithology. Now i would like to model the extension of the schist, which is in a kind of fault, crossing the project area. The schist layer extends horizontally and vertically. The goal is to develop some cross sections, showing the schist extension horizontally and in depth, in order to adjust the excavation method (schist is weak, whereas amphibolite is damn hard). How could i model the "edge" of the schist and some lenses of amphibolite in the schist? Thanks a lot, Chris
