Scaling a line

Hi all,

I scaled a center line in model space to make the brakes visible and it is fine in model space but when I go in paper space it seems that the scaling has no effect b/s the line still looks solid.

Any suggestions?

Tx.

What is your viewport scale?

1. My viewport scale is 0.0394.

But this is another question I had.

2. Here is the situation: I have a drawing that I imported and I left the drawing to be 1:1; dimension scale factor is 1 so that when I offset and draw when I type in 1 it means 1. Very often my colleagues scale down drawings by 0.394 and change the dimension scale factor to 25.4. I don’t like that because when I want to draw a 1mm line it becomes 1inch line.

3. I have made my drawing to appear as 1:1 in paper space by scaling the view port by0.0394. This is something that confuses me given the settings I established in the dimension edit.

Here is some good advice I'll pass along from GE regarding your scaling issue:

"I think you need to read up on LTSCALE and PSLTSCALE..."

Remember that you should draw everything in model to FULL size. Then switch to your layout, create your viewport(s) and scale according to your needs.

Where are you doing your dimensioning? In model space or your layout?

Everything is done in model space (layout text, title blocks etc. in layout space).

Can the scale factor on the viewport be changed. I don't understand why i have to scale the viewport to 0.394 sot that it would show 1:1. Does that mean that my drawing in model space is 25.4 times larger than I wanted

Dimensions in model space too? If so, are you using annotative scaling (I'm guessing that you aren't)? If you did not draw the objects at full size in model then you made a mistake.

The model is in full scale (in model space) dimensions are (in model space):primary units>measurement scale>1.000.

But the in Layout space when I create a viewport to show the drawing, in the Viewport toolbar I have to type 0.0394 in order to show the drawing in 1:1. If I select 1:1 in the same viewport toolbar it shows the drawing larger (I assume by 25.4).

Sounds like your drawing is set to millimeters when you want it to be in inches, or the other way around. Unless there is some reason that I can't figure out - decide if you want to draw in millimeters or inches and stick to that.

What size paper are you plotting to?

How large is this object?

If the object is larger than the paper it will be plotted to then it would make sense that it would need to be scaled downward. On the other hand, if the object is so small that you would need a magnifying glass to see it (or very good vision) it would have to be scaled upward. In light of this think about the object you have drawn and your viewport scale.

When we plot from a layout we should be plotting at 1:1. We let the viewports handle scaling issues.

If you are going to insist on placing you dimensions in model space then you ought to consider using annotative scaling especially if you are going to have more than one viewport and use more than one scale.

The model is in full scale (in model space) dimensions are (in model space):primary units>measurement scale>1.000.

But the in Layout space when I create a viewport to show the drawing, in the Viewport toolbar I have to type 0.0394 in order to show the drawing in 1:1. If I select 1:1 in the same viewport toolbar it shows the drawing larger (I assume by 25.4).

the reason for this could be the paper size you are selecting. for example if you are doing A3 PRINT, for metric drawing you need to select A3 but for imperial drawing you eed to select 11x17.

it had happened with me recently so i know.

My suggestion would be to experiment with the "Use paper space units for scaling" toggle at the lower left hand side of the Linetype Manager window, along with the Global scale factor.

I believe this should be toggled off for your paper space to look like your model space.

Thank you all,

I am in the way of figuring it out. All the scaling problems were coming from the Layout Setup in particular w/ Page Setup. I was using predefined company Layout (8.5x11)that had Plot scale>scale 1inch=1unit. However I wanted my model and drawing to be 1mm=1unit. I created a new Layout where paper size is in mm. units are in mm and scaling is 1:1. That is all good.

Where are usually the company title blocks, revision tables etc. Here, at my work they are in Layout space. Now when I am creating a new layout from scratch I have a hard time centering anything on Layout space (e.g. how do I stretch the viewport right to the corners of the white area; all I can do is eyeballing but don’t like this).

One of the options for sizing viewports in Fit. You do realize that you can zoom in during the sizing of the viewport to achieve a bit more accuracy in your picks right?

Yes I know that but the more I learn the more I realize how much I don’t know. I am reading about fields and fields codes for setting up automatic title blocs. It is a little over my head at the moment.

When you figure it all out come back and teach me what you learned. I could use a refresher course. LOL

Absolutely…
