I prorate lots/block using the autocad align/scale command.
I only know how to do this with straight lines
Does anyone have have any tips/links/ tutorials on how to use CAD to do this with curved portions of blocks?
In my area we use a lot of curb splits to generate the measured block dimensions.
I hope I'm not misunderstanding your question, but what I would do is to combine my lines and arcs to a polyline. I would then use the Divide command, which will place (Autocad) points equally along the polyline. You won't really see the points unless you change your point type, but you can still use osnaps to find the nodes.
Other software addons will probably give you similar routines, but it's possible to do with vanilla Autocad.
One way to prorate radial lines is to prorate the delta angles.

Ding Ding Ding!!!!! We have a winner!

Mathematically this is the correct way to do it.

As for doing it in CAD, the Divide command is the best. IF THEY ARE ALL EQUAL DISTANCES.
If Divide doesn't help, you can always use MEASURE to set nodes at the required distances.
Create a poly-line of all your record information of the R.O.W. then set the poyline on a point you wish to hold, rotate and scale it to another point on the R.O.W. you wish to hold, this will scale all of the points in between or you can make it a Block and do the same thing, then explode the Block
Civil 3d (and I assume AutoCAD as well) has a really handy command to "create a point along an arc". You don't need anything other than arc distance. It's a lazy way to door,but can be a huge time saver I'd you have a lot of them.
I usually use the arc length to proportion, then recalc. the delta.
I don't use the rotate and scale on polylines with curves because it changes the radius. I do use it on straight lines.
I will draw in CAD and create divisions and arrays and other tricks to get the drawing correct.
Still, all my calculations are done in COGO.
Hi friends who can explain method for open traverse with Totalstation and automatic level machine? Road length is 35km

I like to see the numbers and solutions of bearings and work from actual points with coordinates.
CADD solutions are not always what they appear and then you have to pick points to have any actual values to download as a coordinate file.
You can also use the command LENGTHEN ('Total' option). You can specify lengths to arcs or straight lines.

"CADD solutions are not always what they appear..."
Can you clarify this statement? I abandoned COGO in 1985 when I realized how much quicker and more intuitive CAD was. I've never had a problem that I am aware of. Just curious what you mean.

I imagine your screen is full of icons to click on to perform your inverse and area and intersection and most of the other functions you use.
I would rather use the keyboard and input a two letter shortcut to do all the same and look at the bearings and distances to a tenth of a second and ten thousands of a foot to make sure the number on the plat rounds off correctly.
Mouse work is ok, it simply does not suit me as well as using the keyboard.
An associate of mine just sent me coords of something he did and checked into a WGS84 based network I already have in place.
Problem is with his settings because the coordinates he sent are in State Plane North Central and show between 1 and 3 decimal places.
My cogo uses 27 decimal places for raw computations and never store less than 7.
I have adjusted the settings of my Carlson CES to give me good numbers that I can download into an ascii file if necessary.l
Working with a mouse all that much builds a huge callus on my wrist.
Whatever works, right............;)
I actually prefer to COGO most jobs - provided they aren't extensive. It keeps the grey matter working at visualization.

Another command missing from the Carlson OEM version
