Re: Indication of drawing scale

Hi 

 

besides the sheet draftscale value there exists a couple of macros for automize this task.

 

One originally came from Klaus (www.incobase.de) which I modfied a little to fullfill my concept of drawing scale.

 

 

It calculates all scales on a draeing sheet (only principal views) finding the master scale and all second scales.

 

This will be written into a draft property (or 2) for use in the title block.

"I can overlay two printouts to get a visual idea of interference"

 

It's been so long since I used that technique that it didn't really register. Seems to me you need very translucent paper like old vellum paper or mylar and/or a good large light table. Neither one in supply where I've worked in years. And if the scale is fractional because the parts/assemblies are large the resolution is going to be lousy.

I take it, @bshand, that you don't do much government work.

Smiley Happy Indeed I don't. Started out doing so many moons ago. How does that relate to this though?

The government is slow to adopt change, at least some areas, therefore we are required to continue obsolete practices (like scale on drawings) in order to satisfy their requirements.

Although I thought the argument for scale you made supported indicating scale in some cases at least and perhaps having that argument in mind is why gov't standards still require it. But then I'm imparting the virtues of logic and reason to gov't regs and therefore may be, umm, out of my mind.

Amen Ken! However, "New School" is paperless. An "electronic" drawing should go straight to the machine tool that fabricates it! That is the fundamental weakness of Solid Edge, because it cannot translate directly in real world coordinates to DXF that many machine tool manufacturers use. If the maker would like, I could supply a Hessian Transformation algorithm.

I'm not sure I follow that as most CNC apps that I am familiar with that do anything besides 2D sheet metal take 3D formats like STEP/IGES/Parasolid, and of course sheet metal flat patterns can be exported directly to DXF for those CNC situations...

Hi Grundey,



The sheet metal flat patterns are close, however; there is a massive amount
of chutes and hoppers, bulldozers, mining equipment, etc. that are drawn by
the company engineers on standard blue print paper. The parts can be 8 feet
by 20 feet, however; sheet sizes are seldom over 36 inches. The engineer
scales the drawing so that it fits on paper, thinking the job is done, and
he has thousands of file that are like that. If there were some way to
translate the drawing scale with the AutoCad translator, then the dxf could
be interpreted precisely as the engineer drew it as it is imported to XY
oxyfuel or plasma cutting tables.
