setpropertyvalue

[abra-CAD-abra]

All,

 

setpropertyvalue

 

I am trying to use the above function to manipulate viewport overrides for layers.

 

It works as expected with the following layer property names:

"ColorOverride"

"IsFrozenInCurrentViewport"

"TransparencyOverride"

 

However, I cannot successfully apply values to the layer property names below:

"LineWeightOverride"

"LinetypeObjectIdOverride"

 

I am able to successfully retrieve values for the above using the getpropertyvalue function but I cannot apply properties.

 

Examples:

(setpropertyvalue (tblobjname "LAYER" "TEST-LAYER") "LinetypeObjectIdOverride" "BORDER"))

returns: "error: ADS request error"

 

(setpropertyvalue (tblobjname "LAYER" "TEST-LAYER") "LineWeightOverride" 15)

returns: "Lineweight rounded to nearest valid value of 2.11 mm"

It works as expected only for values of 0 and 1. All other valid lineweight values are either rounded up to  2.11 or down to 0.0. For example, it will not accept 13 or 1.3.

 

Can anybody shed any light? Any guidance would be much appreciated.

 

Cheers..

You are value you are supplying is incorrect

 

When you (dumpallproperties) you get

 

LineWeight (type: AcDb::LineWeight)  (LocalName: Lineweight) = -3
LineWeightOverride (type: AcDb::LineWeight)  (LocalName: Viewport Lineweight) = Failed to get value

and

LinetypeObjectId (type: AcDbObjectId)  (LocalName: Linetype) = 7ffff603960
LinetypeObjectIdOverride (type: AcDbObjectId)  (LocalName: Viewport Linetype) = Failed to get value

"Border" is a linetype "name" NOT an objectID

 

and I suspect that the same is true for lineweight

 

accepted Lineweight constants

acLnWtByBlock

Dlanorh had a similar problem, can see the mixture of numbers, strings and known names.

 

(vlax-for ent block 
(vla-put-color ent 0) 
(vla-put-linetype ent "Bylayer") 
(vla-put-lineweight ent aclnwtbyblock) 
)

Guys, thank you for your responses.

 

When I dump all properties for Layer "0" inside an active viewport, it returns the following:

 

LineWeightOverride (type: AcDb::LineWeight)  (LocalName: Viewport Lineweight) = 100
LinetypeObjectIdOverride (type: AcDbObjectId)  (LocalName: Viewport Linetype) = 216decd3960

 

The return value for the LineWeightOverride property is 100 which is 1.00mm.

 

Similarly;

(getpropertyvalue (tblobjname "LAYER" "0") "LineWeightOverride" 1)

returns 100.

 

If the VP Lineweight was 1.3mm it would return 13. I cannot assign a value of 13 using:

(setpropertyvalue (tblobjname "LAYER" "0") "LineWeightOverride" 13)

It returns "Lineweight rounded to nearest valid value of 2.11 mm"

 

 

For LinetypeObjectIdOverride:

 

I can retrieve the name of the linetype using:

(setq val (getpropertyvalue (tblobjname "LAYER" "0") "LinetypeObjectIdOverride"))
(setq ltn (getpropertyvalue val "Name"))

This returns "Continuous"

 

However, I cannot set this value using:

(setpropertyvalue (tblobjname "LAYER" "0") "LinetypeObjectIdOverride" "Border")

How do I access the objectID? 

The arguments for setpropertyvalue are as follows:

(setpropertyvalue ename propertyname value [or collectionName index name val])

BIGAL, the above vla-put functions don't work for vieweport overrides. You would expect those functions to cater for all.

Have you tried :

 

(setq val (getpropertyvalue (tblobjname "LAYER" "0") "LinetypeObjectIdOverride"))
(setpropertyvalue val "Name" "Border")

[dlanorh]

I have to ask this, but I hope you are trying to run viewport overrides whilst looking at modelspace through an active paperspace viewport.

Yes. This also returns: ADS request error
