Model space scale vs layout scale

When i copy paste from model space to layout i need to reduce size of objects by 1 to 10. 

 

I must use different dimstyles for same object once it is displayed on a vp. Of course this happens once i add dimensions while in layout space.

 

When i use the command CHSPACE, objects are moved with proper size.

 

Of course printing must be considered.

 

How can i force same size of objects when cut paste from model to layout space and vice versa?

Why copy to paperspace? The scale factor for chspace depends on the viewport scale. Post a drawing.

That is what CHSPACE is used for: your modelspace content is larger by factor of 10 because you are using a 1:10 viewport in your layout perhaps?

Thanks Pendean, probably you are right.

 

How can I prevent this 1:10 relation of the viewport in my layout? Is it possible to keep it 1:1?

Of course the default printing with proper 1:100 scale is most important.

 

Thanks a lot

It depends, are all the model content drawn at 1:1 scale, and at 1:1 do they actually fit on a sheet of paper the size of which you have defined in the layout? Otherwise you can only use CHSPACE to move and scale content between model and paper space, if you don't like to do it manually.

Attached is a sample of a small drawing.

You can see in the magenta circle two dimensions of same size showing same dimension, in model and one in paper, for that I need to keep double dim styles.

 

How can I keep this drawing with same scale in the model and paper?

 

in the current setting of this file, the paper will plot properly with height of 90 centimetrs.

In the file attached to the previous post, the layout is 10 times larger than the model space.

 

Thanks

I looked at your test drawing.  I can offer some suggestions but I don't think they're what you want to hear.

  • AEC object and everything that represents real world size object should never be moved to paper space.
  • ACA global really works best and is intended for use with millimeter, not centimeter size units.  If for example, I attempt to dimension your drawing using AEC dimensions, the values are 10 times larger. For some reason, probably due to a bug, the AEC dimension system doesn't acknowledge your centimeter units.
  • AEC objects can't be transpatially dimensioned.  They must be dimensioned in model space. This means that if you try to dimension AEC objects through a viewport, you will need to use the reciprocal of the cannoscalevalue as the dimension measurement scale factor.

Using ACA most efficiently requires rethinking your methods and processes.  These are recommended:

  • Use the project navigator to manage your project (constructs, views, sheets, and project related information).
  • Put no annotative elements in constructs.
  • Do all annotation in view drawings (tags, dimensions, notes, schedules, etc.)
  • As much as possible, use AEC dimensions, which update automatically when AEC elements are moved.
  • Drag views onto sheets.  Sheet drawings contain only one layout each and only contain a titleblock and the views (xreffed drawings with automatically created viewports and titles).

It sounds like you want to work seamlessly between model and paper space so that you can measure the same distance each way, use the same dimension style, etc. Is that correct?  I'm so stuck in the imperial measurement system that I might not be much of a help to you other than to suggest that you need to look at paperspace like model space printing and make your page setup reflect that difference. I've attached your dwg as an example.  When you work this way, you may find that working with different scales in the same dwg can be more challenging but it can be done.

Thanks avengineering,

Your answer covers my question and looks like different scales are also easily manageable.

I use "Export layout to model" in order to transfer 3D drawings to others that use only 2D. Looks like your suggestion solves also some scaling issue in this case as well.

But, looks like that for the generated file, Autocad takes the Plot Scale from the past and does not use the new plot scale that I am using now. How can I change the default plot scale?

It appears you don't want to follow recommended procedures at this time.  After you get tired of the extra work, come back to this thread and review these links:

1. AutoCAD Architecture Knowledge Base Tutorial on How to Create Views (general:plans and elevations, sections, and details.  The video includes tagging, dimensioning, and how to set up model space views.  The followup video demonstrates how to place views on sheets.

2. The landing page for the AutoCAD Architecture Tutorials

"How can I change the default plot scale?"

 

That can be done by saving a page setup and assigning it to the viewport. Once you have the viewport set, you can save it to your template by using the import option in the pagesetup dialog.

Hello dbroad,

 

somehow I missed your previous last post.

Your observation regarding my work is amusing and actually correct. I Intentionally, do not use some of Autocad abilities, this is mainly because I do not have the time to learn nor the need for that.

 

You mentioned a bug with the 10 times between the model and the layout, actually I found several annoying bugs with Autocad which remain bugs for year. 

 

Thanks a lot for your educating help.

You're welcome.  If you decide to continue using ACA, you should find that learning the correct procedures is an investment in future productivity and reliability. The AEC dimensions, for example, bugs not withstanding, very worthwhile features. They only work in model space however.  Annotative scaling is also a worthwhile feature. Good luck.

As I read this it sounds like we just ditch paper space and go to the Project Navigator workflow?

The Project Navigator workflow does not eliminate the use of layouts and paper space.
