khoshravan posted a topic in AutoCAD GeneralThis question may not be related directly to this Forum but probably somebody might have the knowledge to answer. Please have a look at following site. http://www.cut-the-knot.org/Curriculum/Geometry/Griffiths.shtml It teaches geometry with animation embedded to drawing. You can drag points with small circles. Drawing and all related objects will change accordingly. This is very nice and fantastic looking from education stand point of view. I want to build something similar. At first I thought it is possible to construct something similar with aid of “constrain” in AutoCAD but it is not easy. I want to know in which programming language they are programmed. And where can I get related information (in beginner’s level) to start learning. Apparently it is java language as mentioned in index page but I am wondering how the author does it with java.
khoshravan posted a topic in AutoCAD GeneralIn triangle ABC, AD is drawn as angle bisector and BE is drawn perpendicular to AD. I want to draw these two lines and triangle ABC by means of constrains, so that when I move point A (make it bigger or smaller), I can get those two lines move automatically. What kind of constrains should I use? For triangle itself, I use "coincident" constrain. I think this part is correct. Whenever I move a vertex after selecting a line and using red grips, it responds and triangle reshapes. Do we have angle bisector constrain? I draw angle dimension line for two equal angle and tried to impose equal constrain for these two angle but couldn't succeed. Drawing11.dwg
khoshravan posted a topic in AutoCAD GeneralI have an angle and I have drawn its bisector. I want to constrain two bisector angles to be equal so that if I change one of bisector angles the other one changes automatically to maintain the equal value. I am new to constrain command in ACAD 2010 and haven't mastered it but I think it should not be difficult to do it with constrain command.
