Searching for Objects in an AutoCAD drawing then highlight.

I was told by a fellow architect that there is an Architectural Desktop plug-in that allows you to search for a particular block and its attributes in an AutoCAD drawing and then have that attribute (or just block) and highlight in a special way. It kind of takes the block and its attribute's lines makes them into a dash and then does a type of animation where the lines become solid for a second - which allows for an effect where that block or attribute is blinking! After some research here on this site - I've got all the coding I need to find all attributes of all blocks in a particular AutoCAD drawing. But I'm not sure how to search for something I'm not sure that is out there. Is it animation that allows a particular object to be "blinking" or is there another effect that can be applied to a particular object? If I can get the VBA coding for that technical term than I would be all set to put it in place! Thanks for any help! Sincerely, Stephen LeCompte Jr.

 

Hi Stephen,

Assuming you have an Object from the drawing you can change any of its
properties sequentially to give the appearance of motion of blinking or
anything.

The variable Object could be a group of objects, or a layer, whatever you
want.

The general principle is:
With Object
Do while Not SomeEvent ' The method to stop it running"
.If Linetype = Dashed Then ' This uses linetype - you could use
anything
.LineType = Continuous
Else
.LineType = Dashed
End if
.Update
DelayEvent ' Code so it doesn't run too fast to be seen
Get SomeEvent ' The opportunity for the user to insert the stop
event
Loop
End with

instead of changing the linetype, why not just set highlight true or false? ie. Object.Highlight True

 

Hi,

As I tried to indicate you can test and change anything.

Here is an interesting effect using a selection set of lines. You can
change the timing to get different effects:

For i = 1 To 25
For Each oLine In ssetObj
oLine.Color = Int(i * 10)
oLine.Update
Next
K = Timer
Do While Timer - K < 0.025
Loop
Next i
For Each oLine In ssetObj
oLine.Color = acByLayer
oLine.Update
Next

false? ie. Object.Highlight True
