Hi,
>> when I use offset with through
With option THROUGH you are specifying a point, but not a distance.
If you want to have 200 as offset-distance, then don't use the THROUGH option, just enter the distance, that's it.
Why do you get strange results when you are using the option THROUGH the following happens:
- you are asked to show the object to offset (at a specific point, that will be important later)
- you selected option THROUGH
- you positioned you cursor to any position near your graphic and enter 200
NOW ... your current mouse position in relation to your first point (important as described about) defines a vector and entering 200 means for AutoCAD (like drawing a line with the second point):
"From point 1 in direction of current mouse with a length of 200" ... that is the point (again important:) your new offset object has to go through.
And as long as your mouse position is not 90° from your entity and point 1 the offset distance will always be smaller than the distance you enter.
Maybe this video shows the effect, I run offset and along the orange dashed line and that shows that it's just the "through-point" you are defining by start-point/direction/distance:
