Re: Autocad line arc intersection question

I have to say that you haven't been making it easy for us to understand what
it is that you want to do.

For this last example do the following:

Method 1:

Draw any line perpendicular to the street on either side of the building.

Draw a line from a TANGENT to the curve to the PERPENDICULAR of the line.

Extend/offset the line as required.

Method 2: (assuming the curve is an arc)

Set your UCS to the street line.

Draw a line from the QUADRANT of the arc with ORTHO on.

Extend/offset as required.

That's still not it. The second is close but if I pick the point on
the arc and the slope remains then it will likely cut the arc at two
places like a cord. I want to pick a 'direction' for the line to
move, for example the y direction or x direction, then move the line in
that direction until some point on that line touches the arc. Only one
point of intersection.


Here is a design example: suppose you had a plan for an irregularly
shaped curved building. Suppose there was a street running in front of
the building and you wanted to build a sidewalk parallel to the street
but also touches the building at just one point. So you draw a line
parallel to the street then move it in a perpendicular path to the
street until it first touchs or intersects the building.
