Riddle me this....linetype scale

[workster]

Hi All,

I have come across something strange and I was hoping that someone out there can answer what I hope is a very easy question.

I have 3 charts (each a seperate .dwg) all at 1:5000 scale. These 3 charts form a series with a good degree of overlap. Running through all 3 of these charts is a line which I have given the CENTRE linetype.

Now for the fun...

For the line to look and plot the same on each of the charts I have had to set the linetype scale to '25' for chart 1 and to '0.7' for charts 2 and 3. Does anyone know why this is and why it isn't a standard set value? If I set chart 1 to '0.7' or charts 2 & 3 to '25' they become solid lines and therefore wrong!!

I have checked that all system variables are the same for each chart, and there seems to be nothing inconsistent between the charts.

Someone please explain this to me........... :?

Well hunnybun,

do you plot from model space or paper space ?

I guess (hope) from model space ... now put you're psltscale on 1

[YosSa]

check the linetype scale of each individual line, they could be different

[workster]

Hello once again,

I had already checked that the psltscale was set to 1 and swapping it between 0 & 1 doesn't help.

Ummmm,

So just to confirm, 1 line has to have a linetype scale of 25 and the other 2 lines a scale of 0.7 so that they look (on screen) and plot the same as each other, EVEN THOUGH the charts are all at the same scale and it seems that all the drawing settings are the same. Confused? I am......

Thanks for you reply though, keep on keeping on...

if you type ch in youre command line.

then select 1 line .. loko at its ltscale

now select the other 1

is it the same ??

Hey bud,

I think your grasping at the wrong end of the stick my friend.

The lines do have different linetype scales because I have given them different linetype scales. I had to do this (25 & 0.7) because when I initially plotted the drawings when the lines were all set with a linetype scales of 1 they plotted differently. This is when I noticed that I had to change the first drawings linetype scale to 25 to make it match the second drawings linetype scale of 0.7.

I don't see why they should need different scales as the drawings they are on are all at 5k, but I am working in model space so this shouldn't matter anyway. But for some reason the first chart requires a larger linetype scale where as the other 2 require smaller linetype scales.

I have copied the lines between the charts and they copy with their own linetype scale and still look OK. However if I copy the 25 linetype scale line into the drawing where they lines are set to 0.7, then change the 25 line to 0.7 it all looks wrong. If I set them back to 1 they also look wrong.

I hope this has helped explain the situation better. Keep plugging away....

they should never have an diff. lt scale, thats the point ....

if you insert the diff. drawings in 1 drawing the prob should be solved

Hi,

probably you should check the sysvar MEASUREMENT. It should be equal in all drawings

[workster]

Hi Bob,

Thanks for your input. I have checked the sysvar MEASUREMENT and all drawings are set the same (0).

I'm still not understanding why to look the same (on screen and on hard copy) the lines NEED different linetype scales, otherwise if the have the SAME line type scale they look different (on screen and hardcopy)

I'm going bald from all the head scratching..........over to you guys!!

[YosSa]

Are the lines in the same drawing ??

[workster]

Hi All again,

This time I have enclosed the drawings (simplified) with the troublesome lines.

The first chart you can see has a CENTRE type line at scale 25.
The second chart (overlaps the first) also has a CENTRE type line but at scale 0.7, but looks the same as the first chart.

You will notice if you play with the charts that if you change the linetype scale to the same value the lines no longer look the same.

I hope this will help someone shed some light on what I am doing glaringly obivously wrong.

[YosSa]

In drawing 1 the linetype is CENTRE
In drawing 2 it is CENTER

thats not the same hun :)

[workster]

what they say about isn't true Yossa!!

damn yank spellings!

thanks a bunch chicken, I'll make sure I read things better next time.

Out.....
