Trying to create a circle of 850 m diameter

[p2000]

Hello,

I am trying to create a circle of 850 m diameter to be the path for a swept boss or extruded boss and SW is not accepting it, is there a limit for parts dim. in SW ?

thanks

Hi p2000,

There shouldn't be a limit. Just for kicks, I tried this with no problems...

I have SW2008, SP3.1, 64Bit

When i draw it, it's there but when i try to use smart dim. it disappears and i can't set the proper diamter

Hi,

If you still see the leaders of the dimensions but the text is not there, or is a small dot, try changing the Doc Properties settings to "Always display text at the same size"

After drwaing the circle and click on smart dim to set the proper dim it disappears, and even if i will accept the current dim = 852992.22 (as an example) and click on exit sketch to continue the circle will disappear and the sketch will be deleted as if you didn't draw anything in it.
Clicking on F to get the full size , it will ignore the circle and will only show the original drawing.

So i don't think its the dimension font or text
regards

and when i draw a small circle ( will be accepted normally) but when i go for smart dim. to set it to 850000mm i got the message saying: "Adding this dimention will make the sketch over defined or unable to solve. Do you want to add it as a driven dimension instead? " and then give me the option to make it : Make this dimension driven or Leave this dimension driving, and in both cases will not give me the right circle relatively to the part.

There is a limit on a dimension, but it is greater than Ø850m.

Linear dimensions are limited to 500m, which should allow a Ø1000m circle.

I just did it in SW2006, no problem. Your error message makes it sound like your sketch is constrained in some other manner. What happens when you try to sketch the circle in a fresh part? What happens when you apply a smaller dimension to your current part?

smaller dimensions are accpeted so smoothly.
the circle's Radius is 850 and not the diameter, I am sorry for that but i was confused,so from CorBlimeyLimey's reply: that 850 m as a radius will not be acceptable.

Is there any work around ?

Thanks

None that I know of.

p2000,

As a workaround try scaling. Use centimeters to replace meters for the parts too big for SWX to handle. Your 850m circle can easily be drawn at 850cm. If you already have something modeled in meters you can scale it down to cm and still use it.
