Hi,I want to prepare a Longitudinal Profile but how can I fix the both Hiorizontal and Vertical scale separetly.Anybody please help me........

With regular CAD, there is no way to draw separate horizontal & vertical scales.  Two ways to achieve vertical exaggeration of drawn objects:
-First exaggerate the vertical by first scaling your Y values before drawing polyline, or
-Draw to actual station(chainage) and elevations, then make a block of the objects, insert it with x scale =1, y scale=exaggertion. Then you can explode and rejoin lines to a polyline if desired.

I think I've seen this thread in another forum area here.  Perhaps the responses can be combined into one thread?

Hi,CarlB has explained it best, so I would do his way as well. Create block then insert it with expected vertical and horizontal scales.

You can also try using XREF. Similar to using block, but you can still have the original 1:1 scale to work on. And scaled to y direction on other drawing to plot.
