Macros can use lisp commands ^c^c(command "chprop" (ssget '((0 . "INSERT"))) "" "C" "ByBlock" "")

copy and paste.... I reckon it should be a double \\, if it is within " ",

In Lee's example he uses "\\" not "\" though. No way of testing either of ours as we don't have that path on our PC's.

Still think you should give it a simple descriptive name like "Red→0.6 h0.5" so it will make more sense to other users who open the drawing. Later you may have a few Dimension Styles to chose from and it will help you pick the right one.

Here is something I cobbled, but if you really need it working, you'll have to debug it further... Regards...

I'hve manage to finishe lisp with good results. Thank you Tharwat for your help with starting lisp. Have a nice day.

Thanks a lot i aveva lot of difficult to learn...and is possible then assign color 200 ti the block ?then is perfect

Like Steven a more global solution using the Gile code you can start with any combination you like 1-B, 1-BB, 1-BBB and so on would pick say the "1-B" pull the "B" suffix and get a number using Alpha2Number then add 1 use strcat "1-" and Number2Alpha so next is 1-C, next 1-D up to 1-Z, then it becomes 1-AA, 1-AB. Picking start text makes it easier to set just that. Need asdfgh want an auto answer or a pick, pick, pick answer. 2nd question is it always a block attribute or mtext or text, may need to do for all 3.

If you don't care what the name is this would make them unique: (defun c:ub (/ b s) (if (and (setq b (car (entsel "\nSelect Block"))) (= "INSERT" (cdr (assoc 0 (entget b)))) (setq s (ssget "_X" (list '(0 . "INSERT") (assoc 2 (entget b))))) ) (foreach e (vl-remove-if 'listp (mapcar 'cadr (ssnamex s))) (vla-converttoanonymousblock (vlax-ename->vla-object e)) ) ) (princ) ) (vl-load-com)

I think your magenta polylines are not that accurate since they are not connected in the center of Mtext objects nor they are connected from the insertion point of each Mtext, so is it okay to get the X and Y from the insertion point of Mtexts ? otherwise you need to specify how did you get that base point that you connected from the original text C2 to the other texts.

Dimension overrides are messy and are lost when the drawing they're in are inserted into another drawing. A cleaner way might be to select a dimension you want modified, modify it in the Properties Palette, then right-click and select Dim Style → Save as New Dim Style… giving it a descriptive name like "Red→0.6 h0.5" Then just change any other dimensions to that Dim Style you want. Next time you need it just import that Dim Style or add it to any templates that Dim Style would be useful in.

Like mhupp a bit more detail not sure where I got this it is part code of a entmake a dim. Uses dxf number rather than VL name. So would use entmod method for your request (CONS 0 "DIMSTYLE") ;Entity Type (CONS 100 "AcDbSymbolTableRecord") ;Subclass marker (CONS 100 "AcDbDimStyleTableRecord") ;Subclass marker (CONS 2 xname$) ;Dimstyle name (CONS 70 0) ;Standard flag value (CONS 3 "") ;DIMPOST - Prefix and suffix for dimension text (CONS 4 "") ;DIMAPOST - Prefix and suffix for alternate text ;;(CONS 5 "ARR1") -DXF CODES OBSOLETE ;DIMBLK - Arrow block name ;;(CONS 6 "ARR1") -DXF CODES OBSOLETE ;DIMBLK1 - First arrow block name ;;(CONS 7 "") -DXF CODES OBSOLETE ;DIMBLK2 - Second arrow block name (CONS 40 100.0) ;DIMSCALE - Overall Scale Factor (CONS 41 1.0) ;DIMASZ - Arrow size (CONS 42 2.0) ;DIMEXO - Extension line origin offset (CONS 43 0.0) ;DIMDLI - Dimension line spacing (CONS 44 2.0) ;DIMEXE - Extension above dimension line (CONS 45 0.0) ;DIMRND - Rounding value (CONS 46 0.0) ;DIMDLE - Dimension line extension (CONS 47 0.0) ;DIMTP - Plus tolerance (CONS 48 0.0) ;DIMTM - Minus tolerance (CONS 140 xheight$) ;DIMTXT - Text height (CONS 141 0.09) ;DIMCEN - Centre mark size (CONS 142 0.0) ;DIMTSZ - Tick size (CONS 143 25.4) ;DIMALTF - Alternate unit scale factor (CONS 144 1.0) ;DIMLFAC - Linear unit scale factor (CONS 145 0.0) ;DIMTVP - Text vertical position (CONS 146 1.0) ;DIMTFAC - Tolerance text height scaling factor (CONS 147 1.0) ;DIMGAP - Gape from dimension line to text (CONS 71 0) ;DIMTOL - Tolerance dimensioning (CONS 72 0) ;DIMLIM - Generate dimension limits (CONS 73 0) ;DIMTIH - Text inside extensions is horizontal (CONS 74 0) ;DIMTOH - Text outside horizontal (CONS 75 0) ;DIMSE1 - Suppress the first extension line (CONS 76 0) ;DIMSE2 - Suppress the second extension line (CONS 77 1) ;DIMTAD - Place text above the dimension line (CONS 78 0) ;DIMZIN - Zero suppression (CONS 170 0) ;DIMALT - Alternate units selected (CONS 171 2) ;DIMALTD - Alternate unit decimal places (CONS 172 0) ;DIMTOFL - Force line inside extension lines (CONS 173 0) ;DIMSAH - Separate arrow blocks (CONS 174 0) ;DIMTIX - Place text inside extensions (CONS 175 0) ;DIMSOXD - Suppress outside dimension lines (CONS 176 1) ;DIMCLRD - Dimension line and leader color (CONS 177 1) ;DIMCLRE - Extension line color (CONS 178 xcolor$) ;DIMCRRT - Dimension text color (CONS 270 2) ;DIMUNIT (Obsolete in 2011, DIMLUNIT and DIMFRAC) (CONS 271 0) ;DIMADEC - Angular decimal places (CONS 272 0) ;DIMTDEC - Tolerance decimal places (CONS 273 2) ;DIMALTU - Alternate units (CONS 274 2) ;DIMALTTD - Alternate tolerance decimal places (CONS 275 0) ;DIMAUNIT - Angular unit format (CONS 280 0) ;DIMJUST - Justification of text on dimension line (CONS 281 0) ;DIMSD1 - Suppress the first dimension line (CONS 282 0) ;DIMSD2 - Suppress the second dimensions line (CONS 283 1) ;DIMTOLJ - Tolerance vertical justification (CONS 284 0) ;DIMTZIN - Zero suppression (CONS 285 0) ;DIMALTZ - Alternate unit zero suppression (CONS 286 0) ;DIMALTTZ - Alternate tolerance zero suppression (CONS 287 5) ;DIMFIT (Obsolete in 2011, DIMATFIT and DIMTMOVE) (CONS 288 1) ;DIMUPT - User positioned text (CONS 340 (TBLOBJNAME "STYLE" xstyle$)) ;DIMTXSTY - Text style (CONS 341 (CDR (ASSOC 330 (ENTGET (TBLOBJNAME "BLOCK" xstyle$)))) ) ;DIMLDRBLK - Leader arrow block name (CONS 342 (CDR (ASSOC 330 (ENTGET (TBLOBJNAME "BLOCK" xstyle$)))) ) ;DIMBLK - Arrow block name (CONS 343 (CDR (ASSOC 330 (ENTGET (TBLOBJNAME "BLOCK" xstyle$)))) ) ;DIMBLK1 - First arrow block name (CONS 344 (CDR (ASSOC 330 (ENTGET (TBLOBJNAME "BLOCK" xstyle$)))) ) ;DIMBLK2 - Second arrow block name ) ;End of list

Yes, that is how most variables work and you either have to remember what the numbers mean, look them up, or use the dump to see what current settings are. I used vdump on a dimension and this are all the current properties you can change (unless they are locked has RO - read only). As you can see most use numbers. So lets say you wanted to show the alternate units in the dims. Currently its set to 0 or off (vla-put-AltUnits obj 1) ;turns alt units on (vla-put-TextSuffix obj "mm") ;adds mm to the end of alt units ; IAcadDimRotated 2798f900 : TeighaX Interface of a dimension that measures the distance between two points and is displayed at a given rotation ; ; Property values : ; ; AltRoundDistance = 0.0 ; AltSubUnitsFactor = NIL ; AltSubUnitsSuffix = NIL ; AltSuppressLeadingZeros = 0 ; AltSuppressTrailingZeros = 0 ; AltSuppressZeroFeet = -1 ; AltSuppressZeroInches = -1 ; AltTextPrefix = "" ; AltTextSuffix = "" ; AltTolerancePrecision = 2 ; AltToleranceSuppressLeadingZeros = 0 ; AltToleranceSuppressTrailingZeros = 0 ; AltToleranceSuppressZeroFeet = -1 ; AltToleranceSuppressZeroInches = -1 ; AltUnits = 0 ; AltUnitsFormat = 2 ; AltUnitsPrecision = 2 ; AltUnitsScale = 25.4 ; Application (RO) = #<VLA-OBJECT IAcadApplication 0000000027634DF0> ; Arrowhead1Block = "" ; Arrowhead1Type = 0 ; Arrowhead2Block = "" ; Arrowhead2Type = 0 ; ArrowheadSize = 0.35 ; color = 256 ; Database (RO) = #<VLA-OBJECT IAcadDatabase 0000000027DF9408> ; DecimalSeparator = "." ; DimConstrDesc = NIL ; DimConstrExpression = NIL ; DimConstrForm = NIL ; DimConstrName = NIL ; DimConstrReference = NIL ; DimConstrValue = NIL ; DimensionLineColor = 0 ; DimensionLineExtend = 0.0 ; DimensionLinetype = "" ; DimensionLineWeight = -2 ; DimLine1Suppress = 0 ; DimLine2Suppress = 0 ; DimLineInside = 0 ; Document (RO) = #<VLA-OBJECT IAcadDocument 0000000027D8C468> ; EntityName (RO) = "AcDbRotatedDimension" ; EntityType (RO) = NIL ; ExtensionLineColor = 0 ; ExtensionLineExtend = 0.125 ; ExtensionLineOffset = 0.125 ; ExtensionLineWeight = -2 ; ExtLine1Linetype = "" ; ExtLine1Suppress = 0 ; ExtLine2Linetype = "" ; ExtLine2Suppress = 0 ; ExtLineFixedLen = 1.0 ; ExtLineFixedLenSuppress = 0 ; Fit = 3 ; ForceLineInside = 0 ; FractionFormat = 0 ; Handle (RO) = "20702" ; HasExtensionDictionary (RO) = 0 ; HorizontalTextPosition = 0 ; Hyperlinks (RO) = #<VLA-OBJECT IAcadHyperlinks 0000000052DECB38> ; Layer = "0" ; LinearScaleFactor = 1.0 ; Linetype = "ByLayer" ; LinetypeScale = 1.0 ; Lineweight = -1 ; Material = "ByLayer" ; Measurement (RO) = 45.7393393773118 ; Normal = (0.0 0.0 1.0) ; ObjectID (RO) = 668216432 ; ObjectID32 (RO) = 668216432 ; ObjectName (RO) = "AcDbRotatedDimension" ; OwnerID (RO) = 668922848 ; OwnerID32 (RO) = 668922848 ; PlotStyleName = "ByLayer" ; PrimaryUnitsPrecision = 3 ; Rotation = 0.0 ; RoundDistance = 0.0 ; ScaleFactor = 1.0 ; StyleName = "Standard" ; SubUnitsFactor = NIL ; SubUnitsSuffix = NIL ; SuppressLeadingZeros = 0 ; SuppressTrailingZeros = 0 ; SuppressZeroFeet = -1 ; SuppressZeroInches = -1 ; TextColor = 0 ; TextFill = 0 ; TextFillColor = 0 ; TextGap = 0.25 ; TextHeight = 0.35 ; TextInside = 0 ; TextInsideAlign = 0 ; TextMovement = 0 ; TextOutsideAlign = -1 ; TextOverride = "" ; TextPosition = (59.5822222174528 27.7485201652591 0.0) ; TextPrefix = "" ; TextRotation = 0.0 ; TextStyle = "Standard" ; TextSuffix = "\"" ; ToleranceDisplay = 0 ; ToleranceHeightScale = 1.0 ; ToleranceJustification = 1 ; ToleranceLowerLimit = 0.0 ; TolerancePrecision = 3 ; ToleranceSuppressLeadingZeros = 0 ; ToleranceSuppressTrailingZeros = 0 ; ToleranceSuppressZeroFeet = -1 ; ToleranceSuppressZeroInches = -1 ; ToleranceUpperLimit = 0.0 ; TrueColor = #<VLA-OBJECT IAcadAcCmColor 0000000052F064F8> ; UnitsFormat = 2 ; VerticalTextPosition = 0 ; Visible = -1 ; ; Methods supported : ; ; ArrayPolar (3) ; ArrayRectangular (6) ; Copy () ; Delete () ; Erase () ; GetBoundingBox (2) ; GetExtensionDictionary () ; GetXData (3) ; Highlight (1) ; IntersectWith (2) ; Mirror (2) ; Mirror3D (3) ; Move (2) ; Rotate (2) ; Rotate3D (3) ; ScaleEntity (2) ; SetXData (2) ; TransformBy (1) ; Update ()

It looks like all of these ideas are good, but if you don't want to go through the trouble, I just use the laymcur command (of course i gave it a smaller alias for speed) and then you can select any object and it sets the current layer to whatever you select. I tried making lisps and scripts for what your doing but we use way to many layers for each dept. Hope it helps!

I think: (defun c:ll(/ lName) (if (and (setq lName(getstring T "\nSpecify layer name: ")) (tblsearch "LAYER" lName) ); end and (setvar "CLAYER" lName) (princ(strcat "\n<!> Can't to find layer \"" lName "\" <!>")) ); end if (princ) ); end of c:ll
