First step for me is to be able to build a Programmable filter that can do the same task as the Plot Overline filter.<br>2. The next one will be to specify the (x,y,z) coordinates of the 2 points of the line given two (r,theta,z) cylindrical coordinates with: <br> x = r*cos(theta)<span style="white-space:pre"><br> </span>y = r*sin(theta)<br><br>Any help will be <span id="result_box" class="short_text" lang="en"><span class="hps">warmly</span></span> welcome :)<br>Thank you very much.<br><br>Francois<br><br>------------ Programmable filter start here ---------------------------------<br>
