Yikes!! I've been using Corel Draw! 8 for years and my favorite tool was the angle of rotation. For example, I would select an object, usually a rectangle that has the point of rotation at end of the narrow rectangle. As I rotated it, I could see how much the angle of rotation in degrees is. Therefore I could type a value in the box and the rectangle would rotate some many degrees. Fast forward to my Corel Draw 12. Now when I click on the same object, the box will display what the angle is in degrees already based on the circular angle startingaat the nine o'clock position. I need it to say ZERO and I can't find the setting to set it at zero
To explain what I am drawing is I rotate a narrow rectange and basically creating a dial face for instruments.
HELP!!
tnx
BUMMER!!! Well thanks to all for the reason why the tool does''nt work anymore
In the example above. I am converting this airspeed to knots. 350 knots is at 648.2 km/h. To determine the exact position
I would run a radial to just past the dialmeter of the existing circles.. Now I would rotate the radial froml 600 to 700 on the dial face and it would
give me a readout of such and such in degrees. Divide that number by 10 and mulitiply thay result by 48.2 would tell me how many degrees in rotation
I needed to go from the 600 mark. Reason for this is to ensure calibration.. Just can't put the graduation where I feel like. I used this technique to draw
these dials and now I got to add an extra math step in calculating this rotation.
I apprectiate everybody's input..
Regards.

You are making it far more difficult than necessary in my opinion. Butr for what you want to do you could use the dimension tool to measure the angle. Then the Tranform Rotate tool to create the sub divisions. If you explain the end result, maybe someone could help better than I. A full dial would also help. Don't ASI's work on pitot tube air pressure, hence the non-linear read out. for speed.
If this is something like you want I can explain further.
You are correct that the driving force is pitot static pressure. But the innards are still built so lthat
when the pointer is at the, say, 40 mph, it is 40 mph plus or minus 2-3 depending upon the airpseed
itself. In my example I did make a mistake--the divide by is 100 not 10 because the area is 100 units from 600 to 700. As I stated, 350 knots 648.2 km/h. Well, where do I put that radial? 648.2 is clearly almost half way between 600 and 700. But to make it more accurate. I run a radial to the 600 mark. (Thus my question; in CD8 it would say 0 degrees, alas CD12 does not) I rotate that radial to the 700 mark and take note of the angle in rotation in degrees. If it's 30.7, I divide that number by 100 wlhich would make it.307 then multiply that number by 48,2 and the result is 14.79. Starting at the 600 position I rotate the radial 14.79 degrees clockwise and I have an exact location of 350 knots.
most of the time I deal with the range in the 10 increments i.e. the range from ,say 10 mph - 20 mph my divider will be 10. To make it even easier i can divide by 5 if drawing radials (graduations) between , say, 10 and 15 It all depends on the original dial face.
I will be the first to say that there probably is a better way, but I've been doing this for 14 years and I have lots of customers from all over the United States who buy Russian and Chinese war birds and want their airspeeds to reflect knots or dual scales (knots out mph in) Or their manifold pressure indicators changed from millimeters per second to inches of mercury
