![]() I've had a word with the developers and I can tell you that BricsCAD is not resting on its laurels. You can also change the accuracy of the grading in Settings - length sampling interval and Angle sampling interval (the higher this is set the lower the accuracy). Here I've gone crazy and shown you what it would look like if they decided to level off the surface between the two peaks of Hawaii. Be sure to set Associativity to 2 or 3 to update the drawing as you update the geometry. As with the boundary lines, the grading geometry can be updated after the grading has been created. You can set the angle of grading manually or with the mouse. Select Create Grading, entity and then the surface. If you need to level off a topographical surface before building, or maybe add a duck pond, you can! First, draw the shape of the new surface area and then set the elevation. In this example, I have created a cross-section of the volcanos, But it could just as easily be used to trim down a plot area. The boundary line can be altered retrospectively. You can create a boundary within and outside of the selected polygon. To do this draw a simple, closed polyline, select Add to Site, select the surface, choose Add b0ndary and select the polygon. You can change the boundary of the site, to reduce the working area and help you focus. 0 - no associativity, 1 - surface only, 2 - grading only, 3 - both. It means that you are able to edit the geometry and then turn Associativity back on to update the model. This can be particularly useful when working with large and complex surfaces. Use Associativity to set BricsCAD to live update, or not, as you make changes. Use SITEEDIT to change individual points, by adding, deleting or moving them. Values of 0 - minimum, 1 - maximum or 2 - average.īreakline left to right: none, 1 maximum, 2 average, and 0 minimum Breakline crossings can be turned off or o. Right: least accurate.īreak lines intersections can be turned on or off. Varying degrees of accuracy when sampling a complex, closed polygon made from curves and straight edges. Each BricsCAD template has a different default value dependant on mm, m, inches, etc. Note: it is important to remember that the value of the drawing space will affect the value set. The lower the number the higher the accuracy. You can alter the complexity of your TIN surface before you create it in Settings.Īrc approximation mid-ordinate distance determines how complex the surface is when created. This can be used when exporting your file and works in a similar way to Revit ®. Site common Add information regarding your maximum building area, including constraints such as height and area. TIN stats provides you with all the relevant information regarding your surface. TIN settings control the contours colors and intervals. TIN Visual style turn contours, triangles, points, and the boundary line, on and off. Once selected, the TIN surface's properties will display in the Properties panel. Bottom left: contour intervals increased. Top left: number of contour intervals reduced. A minimum of three points are needed to create a TIN surface. Choose your first point and enter the elevation value, continue until the surface is completed. ![]() Launch the SITE command and select Place points. For more information on Polylines and splines see here.Īfter that, I simply launched the SITE command, selected all entities and voila. I then changed the altitude and converted the splines to polylines using PE (PEDIT). To do this I found a topographic map online and traced it out with SPLINE. The topographical surface is then created based on the selected points and polylines.įor the example here I created a simplified, scale version of Hawii. Launch the SITE command, choose select all entities, or manually select entities as required. You can create a topographical surface from polylines and/or points.Įxample of a topographical surface created with simple polylines This can be useful when you haven't got a coordinate point file. If your TIN surface doesn't appear, try altering the viewport, you might be too far zoomed in or out. Launch the SITE command, choose Import from file and select the file. The simplest way of creating a TIN surface is by importing point data. You can create TIN surfaces in BricsCAD by importing point data, drawing a range of polylines or placing points one at a time. The SITE toolīricsCAD BIM uses Triangulated irregular network (TIN) surfaces to create terrains. This week I'm going to show you how to make the most of the SITE commands in BricsCAD BIM. BricsCAD BIM, it works in 3D from the ground up, literally. ![]()
