Linking the Dots – Inserting SOLIDWORKS XYZ Curves

A lot of us learn how to produce sketches in SOLIDWORKS, but just what if we’re offered a couple of data-point coordinates that require become linked by a bend course? One typical exemplory instance of this is the importing of 2D coordinates for an airfoil profile – here’s how exactly we do so.

We’ll start at the UIUC Airfoil Coordinates Database, and choose an NACA 4418 airfoil (see gif below).

This database provides X,Y coordinates in the shape of .dat file kind which will be perhaps not presently suitable for SOLIDWORKS.

SOLIDWORKS has the capacity to read .sldcrv files or .txt files that utilize the exact same format as .sldcrv files, therefore in this instance the .dat file should be transformed. To get this done, we’ll copy the coordinates through the database into succeed, ensuring to include just the coordinates and never column-heading notation.

Upcoming, the information must certanly be sectioned off into particular columns within Excel. Go right to the information tab in succeed and choose Text to Columns

Select “Fixed width” after which “Finish”. Maintain through actions 2 & 3 if further parameter control is desired.

We’ve two columns that are distinct want to include a third when it comes to Z-coordinate. The SOLIDWORKS XYZ Curve demand requires all three coordinates.

A very important factor to think about only at that point, is scale. For instance, the coordinates listed here are fractions of an inch therefore will have to be transformed into appropriate general measurements when we desired a realistic airfoil scale. This might be effortlessly done while nevertheless in Excel simply by multiplying the coordinates with a desired scaling element.

Finally, save-as text file (Tab delimited .txt):

Given that the X, Y, Z coordinates are saved to a file that is compatible for SOLIDWORKS, we are able to place them into a design. Read more
