BTech degree from a CFTI (Centrally Funded Technical Institute) with CPI at least 8.0 (on a scale of 10). Post Graduate Degree in Basic Science with NET/GATE Qualification or Graduate Degree in Professional Courses (B.Tech/B.E.) with NET/GATE Qualification or Postgraduate Degree in Professional Courses (M.Tech/M.E. Candidates with qualifications in any of the points (a-f) mentioned below are eligible for a monthly fellowship of Rs.program as regulars (RR) may be considered for the Institute Fellowship (subjected to availability of fund) based on the following norms: When you have all the files ready you are ready to get them lasercutted.Students joining the Ph.D. Here all the files ready for lasercutting: Then give them new colors (red and black) See pictures: You start from the lowest elevation layer (use the number /color to find them). Make a file for every layer, where you have the line(s) for the layer in question and the next. To be able to have the laser cutter to perform two different task (cut - black line & engrave - red line) the lines need to have different colors. To know where to place the next layer you need to engrave it into the previous layer. You need to cut every elevation layer by it self to be able to build the map in height. If you open your DXF file in Illustrator it will look like this: You can use other vector drawing programs to do the same. I'm using Adobe Illustrator to make the files ready for the laser cutter. Your DXF will now have different elevations on each layer. You can know export dxf by going to Project -> Export -> Export project to DXF -> choose all the layers you want, give it a name and choose a place to save it. If you want the diferent elevations to be exported as diferent layers to work with it in illustrator, you can duplicate the layer, only have on elevation visible for every shape file. Right-click, choose Export -> Save Feature as -> save it as a DXF. We now have a file that can be exported to a vector-drawing program. Right-click, choose Properties, press Symbology and choose Categorized, choose Elev layer as Column, and choose what color ramp that makes sense to you. This makes it possible, later on, to make the different files for cutting. To be able to differentiate the different elevation layers we classify them by colors. You choose a condition that makes sense for your project. Meaning I only want my layer to show me the fields that have a length above 50. I have chosen the following expression "Lenght" > 50. Now, right-click on the layer and choose Filter. make sure you turn Edit mode off (press on the pen). This will create a new field containing the length of every attribute. Make a new field name it Lenght and from the left list open Geometry and press $lenght as Expression. Right-click on the layer -> Open table attributes -> open Field calculator. To delete these you need to make a new field containing the length and then filter the small ones out. There will probably be many small shapes that will be difficult to cut and disturbing the understanding of your model. I achieve the best result by changing iteration to 5. Change the setting until they feet your design. If it isn't open already you can find it by going to menu processing and clicking on Tools. I will go with a tolerance of 20 meters, but you might want to try different sizes to get a simplified line that suits your project.īecause the simplify tool makes very sharp curves you might want to smoothen them.Īnother way of accessing the processing tools is by searching for a tool in the processing toolbox. Go to menu Vector -> Geometry Tools -> SimplifyĬhoose the contours as the input layer. Use the tool simplify to reduce the amount of detail. You can now see that the contour has a lot of details. I've only changed Interval between contour lines to 2,5 meters because the geographical area I'm working with only has a 15 meters altitude, meaning I will end up having 6 layers. Set the parameters that suit your project. Go to menu Raster -> Extraction -> Contour. (I could not get this function to work on version 3.10 - I had to install the 3.8 version and work on this one) Choose the input layers you want to merge and press run. Go to Raster menu -> Miscellaneous -> Merge. If you have more then one raster tile you need to merge them. Drag and drop it on the layers window or Layer -> Data Source manager -> Raster -> Find your data -> press Add GeoDenmark data set has bygninger, bebyggelse, trafik, teknik, natur, hydro og administrative inddelinger.ĭownload and open QGIS (go for version 3.8) (Open source GIS software) On QGIS (3.8)ĭanmakrs Højdemodel - Terræn - DHM /DEM Terrain data This is a two part guide, one that explains the workflow on QGIS and one that goes through the process on Adobe Illustrator to make the files ready for the laser cutter.
