Autocad multiple scales is a real pain and also can't scale up hatches

Working with Autocad multiple scales on the same plans involves supplementary settings (elevations, text, etc.).
This additional scale takes time to implement the necessary settings.

Starting from the conclusion that 1:50 scale work is appropriate for most of the project.
The time invested in working on two Autocad multiple scales in parallel for all boards/layouts is not justified.

Autocad Multiple Scales For our type of work

After a few attempts to work and print at a scale of 1: 100, the resulting drawing is non-ergonomic, hard to work, does not fit all the information (texts, quotas, marks, etc.);
Scale 1:50 has proved to be optimal for projects with complex functions, furniture/equipment plans, technological flows, machinery, etc.
In our office, we tested working with Autocad multiple scales on the same plan/plan within the framework of the same project.
After these attempts, we chose only to scale 1:50 for all the blueprints/project.


The choice of working with Autocad multiple scales (1:50 and 1/100) scale work involved a whole set of text settings:

  • hatching,
  • line types,
  • marks,
  • and other spacing elements,
  • non-overlapping, etc.

With a view to establishing a standard model for working on this scale,
these settings experiment have been around for over a year, over several projects.


With Autocad multiple scales we hade a lot of effort and additional settings  to coordinate multiple types of quotas and text or display settings.
It has to be analyzed if the effort invested in the additional settings for the project is cost-effective for the purpose the project has to meet.

Working with multiple quota settings within the same element is cost-effective and productive for producing standardized items, in 3D work programs or automotive / aeronautics industries, etc.
For those who have time, research resources, cost-effective justification, there is a technique of multiple quotations and notations “Annotation Scale” 

Hatching problem

The major drawback to this technique is that  For those who work without hatching, it’s perfect.
For designers who need hatching, CAN NOT scale up hatching;
if the effort to build two types of hatching justifies using this automation with ” Annotation Scale “.

Hard copy

Currently, in Autocad, our boards are worked and printed on paper at 1:50 scale.
At this scale, the boards and all the elements in the drawing can be printed to an optimal size so that they can be read by the authorities, the beneficiary and the construction site.

According to the  Law (Country Law 50/1991, republished on 13 October 2004, Annex 1, Chapter 1, Section 2, point 2.1: the planes (level plan/sections, facades) are taught at a scale of 1: 100 or 1:50;)
In the building site and in the authorities, according to the norms and legislation in force, the plans are printed, approved/signed by the designer, these drawings must also indicate the scale of the drawing.

Different scale information in Autocad

In the sketch above is an element drawn on 4 different scales. (a vertical section through a window)
The window has fewer notations and information at a scale of 1: 200 versus the 1:20 scale.
At the 1:20 scale there are several notations and texts, instead the element is partially presented and we need another one (or a larger plan) to have the other half of the window.

The only exception in which we use two scale types within the same plan/ section/drawing – is for the DETAILS set.
Details are printed at 1:10 scale using a separate set of texts, quotas, etc.
At this 1:10 set, as well as the other set of 1:50, worked on several projects.

In the sketch above, the author presents the magnitude of the text’s consistency relative to scaling the object.

In the bottom sketch, if we were to represent the same object and the related text, you can see the different text sizes and the different spacing settings.

So, four types of text settings for each scale
With x the red color, we have marked the wall thickness line that remains constant
