This tip is a good for doing some preliminary layout sizing.

I still use Mechanical Desktop — and AME previous to that — for obvious and not so obvious reasons. In either I end up with needing a dimensioned fab drawing, which can be in a separate file or on a sheet in the assembly model.

One of my self-imposed rules is all items are drawn to scale — 1/1 — and any drawing that does not fit well on a drafting format is fit by adjusting the scale of the drafting format. So now when you add a dimension or ask for the distance, both are the same.

To ease the task of determining the scale of the drafting format, I created a block to represent the drawing field of the drafting format at 1/1 scale.

To determine this optimal scale, I insert this representative drawing field. Seeing it over the view or views of the part I wish to detail allows me to assign a scale for that particular drawing.

I assigned a macro to the command I created to insert this block, which not only asks for the location of the representative drawing field, it also sets the dimscale, the layer, dimstyle, color, etc.
This has allowed me to give these commands and files to others in my group so the drawings are all similarly constructed and anyone can easily edit the drawing and keep things in dimensions, notes, etc. consistent.
I am attaching the block for the size D format used by most of my clients, and the macro from my menu. It sure has made my detailing much more efficient and consistent.

Notes from Cadalyst tip reviewer R.K. McSwain: This is a good idea for doing some preliminary layout sizing. Note that the attached TXT file contains a menu macro. It's not a script file or a LISP file.

We use a similar macro routine, but it uses diesel so it can be used with ACAD LT. I have blocks or border lines drawn to match our clipped viewport, which is scaled up to the size determined by the CANNOSCALEVALUE value. Looking at it now, it appears more complicated than necessary, but it works, so I just leave it alone! ^C^C_expert;5;-LAYER;A;D;guide;;^C^C^C^C-LAYER;A;S;guide;;;;_tilemode;1;-layer;m;Viewport;;_attdia;0;_-insert;blocks/title_guides/A1_LINEBORDER;s;$M=$(/,1,$(getvar,CANNOSCALEVALUE));0,0;0;$M=$(/,1,$(getvar,CANNOSCALEVALUE));attdia;1;_zoom;e;-layer;a;r;guide;d;guide;;;expert;3
