Once this is complete, it’s business as usual with Boss Extrude etc. If we want to extrude it, we need to create a new sketch and Convert Entities making sure to close any open gaps that may be present in the curve etc. Keep in mind there is really nothing you can do to the curve at this point except edit the coordinate parameters in the Curve Table. Click OK and the curve will be generated. Decimal place accuracy for the table can be controlled through Document Properties > Units. Note: from here it is possible to edit the table (adding/deleting rows or changing cell values). Now that the X, Y, Z coordinates are saved to a compatible file type for SOLIDWORKS, we can insert them into a sketch.Ĭreate a new sketch > Insert > Curve > Curve Through XYZ Points…īrowse to and open the text file. This is easily done while still in Excel by simply multiplying the coordinates with a desired scaling factor.įinally, save-as text file (Tab delimited. For example, the coordinates here are fractions of an inch and so would need to be converted to proper relative dimensions if we wanted a realistic airfoil scale. One thing to consider at this point, is scale. The SOLIDWORKS XYZ Curve command requires all three coordinates. We now have two distinct columns but need to add a third for the Z-coordinate. Continue through steps 2 & 3 if further parameter control is desired. Go to the Data tab in Excel and select Text to Columns Next, the data must be separated into respective columns within Excel. To do this, we’ll copy the coordinates from the database into Excel, making sure to include only the coordinates and not column-heading notation. dat file type which is not currently compatible with SOLIDWORKS. This database supplies X,Y coordinates in the form of. We’ll start at the UIUC Airfoil Coordinates Database, and select an NACA 4418 airfoil (see gif below). Most of us know how to create sketches in SOLIDWORKS, but what if we’re given a set of data-point coordinates that need to be connected by a curve path? One common example of this is the importing of 2D coordinates for an airfoil profile – here’s how we do it. Connecting the Dots – Inserting SOLIDWORKS XYZ Curves
