Dear sir, I need a program for to draw hatching as per condition, multiple selection at time. If separate, separate lisp no issue, if add option for 2 line and 3line Cad file attached with situation and require solution. Thanks HATCHING PATTERN AS PER CONDITION.dwg

I have a plot setup to plot all the layout tabs in a drawing. I have provided the users the options to select the paper size, plot style, and orientation. These are stored as user variables (PDFPS, PST, and PLO). I have the setup working great, but I am trying to set it up where if the user hasn't selected one of the variables, the command will be cancelled. I have tried an if statement, but I wanted to evaluate all three variables at once. I'm thinking it should be doable, just have been able to figure it out. Any help is appreciated. The code below is the code that plots all the layouts and places them in the PDF folder for each project. ^C^C^C(foreach LL (layoutlist)(setvar "ctab" LL)(command (setq DL (substr (getvar "dwgprefix") 1 (- (strlen (getvar "dwgprefix")) 13))) (setq DN (substr (getvar "dwgname") 1 (- (strlen (getvar "dwgname")) 4))) (strcat DL DN);(setq FS (strcat DL "52 PDFs" (chr 92) DN "-" (getvar "CTAB") ".pdf")) "plot" "yes" "" "AutoCAD PDF (General Documentation)" PDFPS "Inches" PLO "No" "Extents" "1:1" "Center" "Yes" PST "Yes" "No" "No" "No" FS "Yes" "Yes" "Yes"));(alert "If all settings were selected, PDFs have been made of all layout sheets and saved in the PDFs folder for this project. They were saved as Project Name-Layout Name"); For reference, I have a code that evaluates each variable and displays a message. (if (= nil PDFPS) (alert "No paper size was selected. Please cancel command and select paper size.") (strcat PDFPS))

I've got an assembly of a crown road and daylight sloping running along a corridor. At one point there is a retaining wall along the shoulder which I want to daylight to (the rest of the road daylights to the original ground). I've inserted a "LinkOffsetandSlope" subassembly that will do what I want in the area of the wall (represented by a feature line). But for areas of the road where there is no wall, it still shows a link running to the default offset. Is there any way I can make this work without making another assembly and separate region? Thanks...
