You may be wondering if it is possible to measure the length of a spline in sketcher or a 3D spline in Generative shape design. In other words, what is the length of the spline if it were straightened out. For example I have a part made utilizing the rib command and it is not made in Sheet metal design so I can't make use of the unfolded view in drafting and measure the length of that part. What do you do?
There are two methods of measuring the length of a spline which come to mind.
- You can create a parameter called "Length" and then you would add a formula. Write length() and place the cursor between the parentheses and double-click on the spline. For example: length(`Geometrical Set.1\Sketch.1` )
- In the sketch, pick the curve and hit measure item. If you don't get the length of the spline hit customize and set length to the edge group.
Now you know several methods of how to quickly and easily measure a 2D or 3D spline in CATIA.
