I have this image I need to be done in CorelDraw. Essentially it consists of two diaphragm(optics) connected by a tube. There are two states needed to be shown: one when the openings are the same and another showing one of the diaphragm closing making the tube narrower. I have started drawing this in Corel but my skills are way too low and I couldn't advance anymore. You will receive the Corel file so you can finish the image. I have also uploaded a picture showing the concept.
