Hi

I'm new to the forum and didn't find this in the topics. Apologize ahead of time if this is a repeat.

New to Autocad, long time user of Maya (Since 1998) and other packages.

What I'm trying to do is to make something with exact measurements in centimeters.

I have height and circumference.

Following the instruction to change properties of the circumference, don't see the area or circumference listed in the properties.

Does someone know a better way to do this?

Need these measurements for modeling or use as a guide to get those exact measurements.

Please help if you have any suggestions.

thanks

Are you working in 2D or 3D at the moment?

Can you post an image to show us what you are drawing?

I'm just trying to make something to meet those measurements to use as a guide.

I have a model of a figure and need a certain waist and height. Thought I could make a guide in Autocad.

This will apply to the model of a bag I'm going to be making as well, so one answer for two items? :)

That's vague at best. Are you still in the 2D phase or have you already created a 3D model?

OK...I'm going to assume you are working in 3D and used the SPHERE command. You are correct in stating that "circumference" is not shown in the list of properties. So unless you can find a custom lisp routine that can create a sphere based on a circumference supplied by the user you are out of luck.

My apologies if my question and answer to your question was not clear and appreciate you taking time to respond.

I created a model in 3D in another program, a human figure.
The waist and height need to be exact. I wasn't sure the other program can create an accurate measurement like AutoCad.
My original thought was to import the model into Autocad and adjust the measurements.
When I was creating the circle and cylinder, the tutorial said to change the circumference and area in the properties. I do not see where that is. I was trying to use the program for it rather than manually do the math for all of them.

I have been using 3D programs since about 1998, and used DataCad back in 1997. Took engineering drawing back then too. So, some terms and other things I understand.

AutoCad is new to me and there's a learning curve. I was unsure where to find what I was looking for.

Any suggestions on the best way to this would be helpful.

Draw a circle then use parametric dimension. Type in "dia1=C/pi"

Where C is a user parameter variable for the circumference

pi is a constant number equal to 3.1415

Thank you! Appreciate the direction.
