That is going to produce some wild loops in the spline, which is why I elected to go with straight line segments. Look at the contour line immediately below the surface. I think you can also select multiple contours to run the blend across, which would maintain tangency.Ĭheck the data carefully because there seems to be some overlap in the contours. To fit a smooth spline through the points instead of straight line segments which is what I did above. The long straight line are where I haven't added a space to start a new curve.Īfter a few separate curves come in, go to the Design tab and click the letter B on the keyboard or find the Blend tool and you can add a surface between adjacent contour curves as shown below. In SpaceClaim, click on the Assembly Tab, click on the File + button and pick a text file formated as shown. I believe the data below are in the wrong order: X Y Z. Can you extract the data from the source and have each contour line separated somehow? I did that by hand for a few curves, but since there are 10,500 points, it would be better to write a program to do this. Since you said this was topographical contour lines, I added a space after a change in the Z coordinate as shown below (I deleted a few 3460 lines to show the space). Note: The order of coordinates in a Point Curve text file is Z X Y.Īll you need to do is put the header as shown here and put a space after every curve. You can import the xyz point cloud into SpaceClaim as curves if you format the data properly. I can not figure out how to get the coordinate system intact while i import the model into Ansys. iges file, and gets imported in the same way? So, I couldn't operate on it with my fault point file.ĭoes the coordinate system also gets exported, intact, while exporting a. step format to import into Ansys.Īs I need to put the faults( which are linear curves in Map view and, I've the coordinates of them) in the solid generated, I found the imported model coordinate system is not the same as has been used to generate the surface in the first place. iges format into ABAQUS and exported into a. I have used Autodesk Civil 3D to make a TIN surface out of it, smothened and got a solid with the surface topography. Then put the faults in the solid and simulate it with the appropriate material properties and boundary condition. I want to make a surface out of it followed by extruding it into a solid. Stating it again, I've a large point cloud data of a reservoir topology.
