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?
We are able to measure distance in meters between 2 points using COGO tools. Though, when meassuring areas (command area) even setting units to meters it shows: "Area = 0.00000073, Perimeter = 0.00343123" which is not expressed in meters. The area in meters is around 8900m2. We are using latitude, longitude LL84 (WGS84). Is there a way to easily measure area over the map using this coordinate system?

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?

View 5 Replies View RelatedCan 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 want to draw in Meters! But when i make a rectangle 30x15m it looks so small that i can't see it in my draw. Using my scale is 1:1 and Units Meters.
I tried changing my scale and my units and the rectangle still looks the same way it was. If i want something to look big, i have to draw in mm, for example, 30000x15000mm rectangle.
But, when i do that, everything go wrong...For example, when i draw a rectangle in mm (30000x15000) and i change the line style in layer command or when i try to hatch/linear dimension and etc all looks very small or very big.
What's the easiest way to draw a floor plan?
I still cant understand about the units. I open acad iso template to work in mm and the insertion scale is also showing in mm.what if i want to draw in meters or cm.

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.
