<p dir="ltr">Hi,</p>
<p dir="ltr">I remember reading an article by Anita Graser explaining that the modeler did not yet have conditional modeling....  I may be wrong as Qgis changes rapidly.  </p>

<br />
there is in the graphical modeling in QGIS the possibility<br />
install error routines, or when an error occurs in the execution<br />
skip to the causative fault? and at the next Process to continue?<br />
<br />
For example:<br />
<br />
-> I use the process "extract After attribute value"<br />
-> Now there is this value not -> entire routine is aborted<br />
-> But instead QGIS should  perform another routine<br />
<br />
Unfortunately, I have found nothing in the documentation.<br />
<br />
Many thanks and greetings,<br />
<br />
Sebastian </div></div>
