##### Create viewport boundary from model space polyline
« on: September 12, 2018, 06:03:43 PM »
Hi i have a lisp code when i select a viewport create viewport boundary from model space polyline. Some timew i need to do the opposite. Create viewport boundary from model space polyline. Is any one  have a lisp code  to do this ?

Thanks

I want to select a polyline or polygon from ny model space and create a new viewport in layout  (if i have more layouts show me a list to select the layout i want). Then opens the layout and give me the option toy pick were to place the new viewport.
The model space rectagle has length dimension (x , y). In viewport the (x,y) dimensions must be (Vx,Vy) and i calculate that

Vx = 1000 * x / scale  , and Vy = 1000 * y / scale        x and y are the rectangle dimensions from the model space

Thanks

I have updated the lisp of the post http://www.theswamp.org/index.php?topic=42149.msg474945#msg474945
now it's only in Italian, I hope it can still be useful

I find this code but is not working on meters . Can any one change the code  to suport this

Vx = 1000 * x / scale  , and Vy = 1000 * y / scale

I think the problem is here

Code - Auto/Visual Lisp: [Select]
1. (setq vpxd (* sf (abs (- (car vpc2) (car vpc1))))) ; Determine horizontal length of selected window
2. (setq vpyd (* sf (abs (- (cadr vpc2) (cadr vpc1))))) ; Determine vertical height of selected window
3.

Code - Auto/Visual Lisp: [Select]
1. (defun c:igalvp (/ vpl vplyes l0 ln layers cp cl cs ofs vpc1 vpc2 vpxd vpyd vpc svpc ssvp ssvp1 sf lpno vpno ssnum vpent nvpc1 nvpc2 nvpc1x nvpc1y nvpc2x nvpc2y)
2. ; Creates layout of Paper Space viewports of specified 2D orthagonal views from Model Space
3. ; Used when all 2D design is done in Model Space at full scale and all dimensioning is done in Paper Space as associated scale
4. ; Start command from destination layout tab
5. ; Program will switch to Model Space for selection of desired objects
6. ; Program will return to layout tab for creation of viewport frames
7. ; First a single viewport is made that includes all relevant views of desired part at the desired zoom level
8. ; The single viewport is copied over itself the number of desired separate views
9. ; Then the overlaying viewports are individually clipped to the edges of the separate views
10. ; The separate views will maintain their original orientation and alignment
11. ; The separate views can be rectangular by specifying opposite corners or circular by specifying a center and radius

Hi smemo. I try to run the code ...i write  cfl  to the command line and gives me this error

Hi Topographer, the ai_utils.lsp file is required to run. In my Autocad is in "C:\Program Files\Autodesk\AutoCAD 2015\Support\it-IT".
Usually installed with Express Tools

Hi smemo . The correct path in my pc  for the ai_utils.lsp is  C:\Program Files\Autodesk\AutoCAD 2017\Support\en-us

Can you update the code ?

Thanks

Hi Topographer,
from "ai_utils.lsp" I use the functions: ai_dcl, ai_abort,ai_acadapp, ai_table.
from line 69 to 76
Code: [Select]
 (cond     ((and ai_dcl (listp ai_dcl)))      ; it's already loaded.     ((not (findfile "ai_utils.lsp"))   ; find it       (ai_abort "CreaFinLay" "Non trovato il file AI_UTILS.LSP.\n   Verifica la cartella di supporto."))      ((eq "failed" (load "ai_utils" "failed"))  ; load it      (ai_abort "CreaFinLay" "Impossibile caricare il file AI_UTILS.LSP"))  )if "ai_utils.lsp" is not loaded probably the path is not present in the file search path options
