Problem:
Client struggles to convert drawings to the company's standard layering, linetype and lineweights, colors, etc.
Client struggles to convert drawings to the company's standard layering, linetype and lineweights, colors, etc.
Situation:
In most cases, different drawing companies/ groups have their own standard of drafting in AutoCAD. Even general contractors and sub-contractors have varying ways of drawing in AutoCAD.
In this client's case, they receive different sets of drawings from different sources which means they have to standardize it one by one.
A drafter has to do these time-consuming steps before the actual job as preparation:
Change the layer according to standards.
Determine the scope and non-scope of the drawing.
Fix dimension formatting and style.
Fix linetypes and lineweights.
Remove unnecessary layers and blocks.
... and doing these already takes up 50% of the total manhour for the job.

As an example, this drawing which is a detail drawing of plant equipment already cost 1.3 hours of precious time which could then be allotted to more productive tasks!
Solution:
Solution:
Automated Standardization Routine
Automate assigning AutoCAD object to designated respective layer, color, linetype and lineweight.
Automatically creates standard layers if not existing.
Purges all unnecessary blocks, layers, formatting, etc.
Converts specific objects such as splines, hatches, section breaks into a set standard formatting.
Detect all overridden dimensions and highlight it.
Goes deep inside blocks and nested blocks and set all elements to the standard without entering the block.
Detects inconsistencies in drawing such as forced dimensions, unstandardized linetypes, unreferenced blocks, etc.
...and many more other AutoLISP commands which helped automate the standardization/ design process by an average of 50%!
In fact, the Standardization Routine won the 2020 annual competition of the company's business groups for its contribution to the group's productivity and overall output!

Fig. 34- Average Manhour Comparison of Manual Standardization vs. Standardization Routine
The Automated Standardization Routine has reduced the man-hours needed for manual detailing work by up to 68.44%, making it a cost and time-efficient solution for the organization. By automating the standardization process, the program eliminates the need for manual intervention and reduces human errors, resulting in faster and more accurate drawings that meet industry standards. The program is particularly effective for larger drawings that require more detail and are more time-consuming to standardize manually.
