Help with Scale

[ClayE7XM3]

Hi everyone,

I am a new beginner using AutoCAD LT and looking for some help with Scaling.

I have a survey file (exported from Survey software) as a .dwg which I've opened in AutoCAD. I then added a New Template (.dwt file) which contains a title block that I'd like to put my drawing in. This file was received from one of our contractors (who works in Microstation). Ideally I need to be able to place our survey files into this at various scales (depending on the size of our surveys which can range anywhere from 100s of meters to kilometers long), and convert them to PDFs.

For this drawing, I need to make an A3 PDF at a scale of 1:200. My units in model space are set to Meters. My plot size in page setup manager is 420mm by 297mm. In Paperspace, the dimensons of my title block are 0.420 x 0.297 so that this fits on an A3 paper. When I plot and print this title block everything looks good.

Inside my title block I've created a viewport showing the survey file. To get a scale of 1:200 I created a custom scale of 1 paper unit = 200 drawing units. However when I select this scale the viewport zooms in too close to the point that it's incorrect. I noticed that when I zoom the scale goes to 0.000xxx so I'm sure I've made an error with the scale somewhere. 

I had a look on the forums already and found people with similar problems but I can't figure out my problem. 

I've attached my files to this post -The DWT file is the one received from our contractor and the DWG is the survey file. 

Any help would be much appreciated!

Cheers

You've changed the wrong thing. Annotation scale is for text if it is annotative

The Standard scale is the one you need to change to the 1:200 scale using the drop drown arrow or in the custom scale just type in 1/200

Both items are ringed in the image below

... also, your DWT's units are in INCHES, as is your DWG file too.

DWGUNITS command, never just UNITS command (that is only for display purposes), is how a DWG file is set to use the units you want (meters in your case)

Also don't forget, PLOT command settings are in mm, which are never meter too (once you convert your DWG/DWT to be the correct METERS scale).
