AutoCad LT DWG problem

[simpsonrr]

I bought the QCad professional for a mechanical drawing I'm doing, but in the future, I may be have to do some P&ID's. I tried loading some of my symbol blocks and a drawing frame and the line weights are all so thick nothing is legible. Will all AutoCad dwg drawings need some kind of re-formating to make them usable? Not every .dwg I have looks like line wt's in the 100's, a couple of them look normal. Thinking about it, the symbols may have been made in AutoCad R14, and some of the other drawings made in AutoCad LT. Any ideas?

An efficient support is much easier with an example drawing. Could you please attache one of those drawings to your post? Thanks.

I can't attach a drawing, they are proprietary, but attached are a couple of symbols. These may be from AutoCad R14, don't remember for sure.
Thanks for your help.

Great - thanks!

Every one of your Layer's has a Lineweight set to "default".

QCAD will read the actual value within the setting in "Application Preferences" (Menu/Edit/Application Preferences/Graphic View/Appearance). You can change that value to 0.25 or what ever fits your needs ...

... or change the Lineweight attribute in every single layer.

Thanks, I figured it was a line weight issue, just didn't know if there was a simple fix, I'll give your first suggestion a try. I didn't want to go through layer by layer to fix problem, seems potentially time consuming.
