I tried fixing the points and sometimes I found the ends of the arc stayed at the fixed points when i changed the radius but now the arc and its end points move from the fixed points. Is there a way to fix the start and finish points when drawing an arc?
I generally do a full circle and then add lines to trim it back to specific locations if I need to match end points. It seems easier in most situations, Another option would be to put in points, constrain them and then do your arc, this way they can not move. I almost always use center point arcs or fillets for most things, it seems easier to put them in as opposed to using point arcs.

Hi Ronald,
Welcome to the Forum. One thing to keep in mind when asking a question here. You should always include at least an image or better yet a file illustrating the problem you're having.
It's hard for us to help you if we don't have a clear understanding of the problem.
That said, Have you fully defined the end points of your arc? Maybe dimension them to the origin?
You said "when i changed the radius." I take that to mean that the end points of the radius moved when you set or edited the dimension controlling the arc radius, or just tried to change the radius by dragging. If that's the case, then you need to lock down the end points, with relations or dimensions, first. Then they can't move. If this doesn't answer your question, can you post the Part file, or at least a screenshot? See How can I attach a file to a forum post? if you aren't familiar with the process. Of course, if it does help, please reply anyway.
Update on my question. My own question is now answered OK. It seems that somehow the options for fixing end points etc was changed. I restored to the original and now the fixed points and the ends of the arc stay together after I change the arc radius. Thanks for all your suggestions, much appreciated.
If your question is answered then please give someone a correct answer, plus that way people can see that your issue was completed...
Roland,
If you could provide an example file that would be helpful. But generally when drawing an arc (using the arc command) you use center point, or three points, the three point option allows you to pick the start and end, then define the arc radios.
