AutoCAD 2010 :: How To Draw A Circle With Diameter Of 1.24E -10m
Oct 1, 2012
What is the smallest object I can draw and "SEE" in AutoCAD? I was hoping to prove a point in my introductiory AutoCAD class, but it appears I have been lying!! I tried to draw a cirlce with a diameter of 1.24E-10m. The dot shows up, but I cannot zoom to it. I tried using an enormous zoom scale, but did not have any luck. I am almost positive my instructor introduced the capabilites of AutoCAD by drawing a full scale helium atom, and that was release 14. Is this still possible? Obviously the atom can be drawn, but what are the zoom limitations?

I have a line and I want from the midpoint of this line to draw a circle with 50meters diameter.
My problem is that my drawing has WGS84 as a defined coordinate system so everything is in decimal degress.
How do I draw the cirle or any other item for that matter using metric units (meters etc) while on WGS84?

Can a AutoLISP command be written to read an attribute in a block and draw a circle with the attribute as the diameter using variables? The appilcation is taking the diameter of a tree trunk (the attribute), multipling by 12, and drawing the canopy circle on hundreds of those blocks. So the circles drawn will vary in size.
Not sure how this could be set up, i'm not familiar with LISP writing at all.
1) Read block, single, mulitple or definition?
2) Read Attribute
3) Varaible of attribute, (attribute is an inch measurement...it needs to be multipled by 12 to get feet for final use as circle diameter drawn)
4) Draw circle, variable, with diameter coming from attribute variable (attribute in inches that is multipled by 12)
5) Center point or circle to be block's base point

According to the tool pallet instructions, I should be able to draw a circle of specific diameter by typing in the "width" dimension, then, according to Illustrator: "you can click on the word Height to copy that value into the Height box." Doesn't work. I've trashed the AI prefs, clicked on the word and on the field, and this simply doesn't work. I assume that I or my system is at fault.

I just don't know enough about 3d to do this simple thing. I need to draw a 3d ceiling light cover that is 20 inches in diameter and about 6 inches deep. The light cover looks like a large Smarty. (yes like the candy)

I'm trying to create a dynamic block that uses a parameter and an attribute definition to determine the diameter of a circle in that block. I plan to export GIS points with diameter in the attribute table into a CAD file with the block definition. I'm having trouble figuring out how to set up the parameters to read to attribute definition and adjust the circle diameter. Using AutoCAD 2013

I spent hours trying to annotate a circle 6 pixel in diameter. Using DrawEllipse passing a 6 pixel square rect. and it draws a square. If the diameter is large ex. 20 pixel then it draws a circle.
The circle should look like this:

When i draw a tangent to a circle and zoomed in i saw that the line isn't actually a tangent, in fact it doesn't touches the circle!

I can't control the location of a 3rd circle using ttr. I'm drawing two circles and then a 3rd tangent to both but I want the 3rd circle to be centered down below the two original ones and all it will do is be above them. See drawing.

I’ve an already drawn inclined line from a fixed point (saypoint (0,2) on Y-axis). The inclination is also fixed (say 150 tothe horizontal). My objective is to draw a circle with one quadrant at a fixedpoint (say point (1,0) on X-axis), so that, the line becomes a perfect tangentto the circle. The diameter of the circle may vary to make the line perfecttangent to the circle.

I have to repeatedly draw a circle with 3P option.
I first invoke the circle command, choose the 3P option.
In my second and subsequent cycles, I click "enter" and have to click "3P" again.
Is there a way my chosen option of "3P" is invoked by default on one or two clicks of the spacebar or enter button?

When I dimension an arc to find the radius, the dimesnions appears as a line going from teh center of the arc to the edge of the arc with the dimension in the middle. I don't want this. I want a leader pointing to the R text and that's it.
I've attached a photo of both scenarios- one dimension is the style I don't want, and one is basically the style I want (I'd like it to be more of an elbowed leader line), but it only appears when I use AutoCAD's ISO25 dimension style.
