![]() (this only needs to be done if the nearest edge snap button is not already highlighted ). This function can be selected from the Build Entity toolbar This is done using CAD > Snap > Nearest Edge. Since we want to snap to construction lines we must set the snap mode. You will be presented with the sub-menu of build functions This function can be selected from the CAD toolbar as follows (activate the CAD toolbar if it is not visible using Tools > CAD Toolbar): To construct the first block, use CAD > Build > FFLoop. The simplest (although the most time consuming) approach is to construct a series of 8 cornered blocks one at a time. In this tutorial a few different techniques will be demonstrated. There are numerous methods that can be used to construct these entities. Position the view so that the construction lines are readily visible.īuilding Footwall Access Drifts and Cross Cuts The model can be zooming in or out by holding down both mouse buttons. Translation is achieved by holding down the right mouse button. The easiest way is to rotate is simply hold down the left mouse button will dragging the cursor across the screen. This is readily accomplished by several means (refer to Rotating the Model and Translating the Model). The access drifts measure approximately 5m wide by 5m high, and the distance between levels is 25m.ĭuring block building or at any other time, the user is free to reposition (translate, rotate or zoom) the geometry to make visualization easier. The file "BULK.dxf" is included with the Map3D installation and should be available to import. In this case the construction lines have been saved in DXF format, so change the "Files of Type" to *.dxf Also the use can right click on any item to obtain detailed help on that function.įirst we must open a file containing the digitized mine plans. We want to start with a clean slate, so we will selectīefore beginning please note that the user can hover over any button to obtain a tooltip identifying that buttons function. ![]() ![]() This format is useful for exchanging construction line data with other CAD software. This format is useful for exchanging raw construction line data with other CAD software.ĪutoCAD-DXF format is a popular drawing exchange file with the extension ".DXF". Point file format is a universal ASCII data file with the extension ".PNT". The mine plans have been previously digitized using Map3D A Map3D model is normally built on top of this construction line data. ![]() To demonstrate model building using digitized mine plans, let's build a simple VRM bulk mining geometry.Ĭonstruction lines are used to define detailed locations of underground features such as excavations, contacts structure etc. ![]()
