I must be missing something obvious. I want to create a scaled drawing. I make geologic cross sections with drill holes that are 500 to 1000' deep. I would like to set the drawing scale to something like 1"=250'. So a 1000 foot drill hole would be a line 4 inches long on the screen. I have gone to the Drawing Scale List and figured out how to create a new scale, but nothing I try allows me to change the drawing scale from 1:1. I can edit the list, but I can't change the 1:1 default. I have tried right clicking, double clicking etc. It seems that the drawing area stays at the original 1:1 scale. What am I doing wrong? I want to make a drawing where I can give the Line command the coordinates 250,0 and it draws a vertical line 1 inch long. I would appreciate any help. Thanks.
ok, If you set up a custom scale...1:3000.
That will equal 1"=250'
You can enter 1" = 250' but when Corel saves it...it changes to the 1:3000 ratio
oops just noticed you are working on CorelCad.
I'm using Draw. Hopefully they are the same.
Thanks, but they are vastly different. CorelDraw is logical when setting the scale. CAD programs not so much. Fortunately my son has an engineering degree, he figured it out. It appears I had to set the Boundary Limits of the drawing to some huge number like 2000 to 1000 then Zoom to the Boundary. Once that was done the Grid had to be reset to something like 100 x 100 at which point it disappeared (might be a bug as it magically reappeared after moving the mouse around and clicking a few times). It appears the Drawing Scale table does nothing to the drawing, it is for specifying printout scales. Would be nice if this program had anything resembling documentation to explain that. The online help borders on useless. I guess you are supposed to buy the $42 online manual.
The drawing should be 1:1 scale always. If a drill hole is 1000ft., then make it 1000ft. Scale only matters when printed onto paper.
You can set it in draftingoptions but you already seem to know that - Have you changed the units you're working in as well?
Also, at 1:250 scale, a line drawn from 0,0 to 250,0 would be 1 foot long if your screen was 1:1 and your units were feet - to be 1" you'd need a scale of 1:3000 - so that doesn't make any sense to me but I might be misunderstanding what you're trying to achieve.
I would think that you would draw your drawing at the appropriate scale for your application. Set the scale for printing it on paper. Use your mouse-wheel to zoom in and out of the screen, because scale doesn't really mean anything on the screen, especially since the program has no idea how big your screen is... But it means something on paper- so that's what Scale affects.
Sorry it's not very good advice - but I don't fully understand what you're asking. If I look at it at face value, I'd say "draw a line 250 feet long, then use your mouse wheel until it's 4" long on the screen". If you can supply some more information, I'll do my best to answer it.

Thanks for the response, I used the same logic you are suggesting initially. I just thought I"ll draw a line 3000 inches long. I did and the line disappeared off the screen to infinity. The natural reaction was to scroll the mouse wheel to zoom out, but there appeared to be a limit as to how much it would Zoom and the line never came close to completely appearing on the screen. It wasn't until my son set the Boundary Limit to something like 4000 and we Zoomed to Limits that I was able to get the line on the screen. From that point the scroll to Zoom seemed to work fine. I'm not sure if I did something wrong of if there is just some finite limit to the scroll capabilities that trying to draw a 3000" line exceeded.
