After you finish the drawing (sketch) it is good to check the suitability of the sketch for further work. With this in mind, it is necessary to check that all lines and radii are in line with our wishes. The biggest problem is the "openness" of the model or the draft, since this may be the cause of the mismatch in further work and may disable the development of the model.
In order to avoid such problems, a CATIA software is a very useful tool that allows you to check the convenience of the sketch for further work with a single click. With this tool, we can also check if there is a sketch, for example, double lines, open or unfinished profiles or overlaps.
When we finish the sketch, we run Sketch Analysis
The tool is located inside the SKETCHER module and is intended to detect errors on the sketch.
You can easily access the tool using the
Then we open a working window with the results of the analysis, and at the same time sketch shows possible errors or anomalies. In the example shown in Figure 2, you can see that the model is open - the green
Figure 1. Example of the Sketch Analysis
Within the analysis itself, we can find additional shortcuts, called Corrective Actions, with which they can fix sketches, create helplines, close the profile automatically, delete angles, etc.
The third Diagnostic card (2) shows whether the sketch is defined, or whether the individual points or lines are exactly defined in terms of the reference / zero position of the coordinate system (shown in Figure 2 in yellow - 4).

Interpretation of terms appearing in the Diagnostic tab:ISO-Constrained: defined in relation to the starting position
You can easily find undefined points and lines by right-clicking on a specific point or line, and in the drop-down menu by choosing Reframe on (5), shown in Figure 3.
This operation will show us exactly the selected line or point, in the middle of the screen, so that we can find it easier.
