AutoCAD 2010 :: Blocks And Layer 0
Mar 1, 2013
Many of the blocks my company uses were created with the linework within the block on Layer 0, and set to ByLayer.
When I insert it into a drawing, I put the block on a layer other than 0, and use that layer to control the color & linetype.
If I Xref a drawing, and want to turn off or freeze a layer I use the Freeze and Off buttons in the layers section of the ribbon (I'm working in 2012). This way, I don't have to figure out what layer an object is on to turn it off.
Here's the problem: When I try to freeze or turn off a layer by clicking on a block, it doesn't do anything to the layer that the block is on. It tries to effect layer 0. Even if I use the list command to find out what layer an object is on, it says it's on 0.
I found this article that seems to explain how to use layer 0 in blocks: [URL] ....
It seems my company is doing things exactly as that writer recommends. But it still seems incredibly faulty.
What is the best way to design and work with blocks? I always try to avoid using layer 0, but that would waste a lot of time trying to override the company standards.

I'm aware of the intricacies of layer zero, and the general rule-of-thumb to draw content inside of blocks on 0 so that the block takes on the properties of the layer it is inserted onto, can be isolated, etc.
I generally follow this rule, and where required, I change the line color inside of the block when I want to maintain a certain lineweight. (lineweights based on my plot settings for colors). My dilema is that i've got an intricate block. I'd like to be able to manipulate this block in a way that you'd isolate layers and change their properties. Is there any way to isolate a portion of lines inside of a block while still maintaining them either on layer zero or another (magical) sort of "transparent" layer?
As an example, i'll use the classic "existing", "proposed" door block. i'll draw the door, swing, and jamb all on layer zero. I will set the the swing portion red and dashed so that both existing and proposed swings appear the same. the door itself will then take on the properties of my existing and proposed door layers, respectively. Now say i'd like to edit my block. I want to isolate the swing portion and color it by layer. (obviously the example is lacking here since it would be easiest to just click on the arc) Can i group items inside of a block, or better yet, can i create a second layer and somehow edit the layer's properties so it is "dynamic", "transparent", or "magical" like layer 0?

When i click on the green line has you can see on the image. The layer toolbar wont show me the right layer, like if it's not working. But i can see the right layer inside propreties.
Is there a system variable to ajust to see my layers inside the Layer tool bar?

What is the general feeling about building blocks on layer 0 then using the layer controls to change the colors etc. after they are dropped into a particular layer?
In other words, I like to build a block labled "sample location" on layer 0 then depending on the layer it is placed in, it can be either red or blue (based on the test results).
I print out my drawings on letter sized paper in color.
Most of the time, my background image is a monochrome or greyscale tiff or a jpeg of a scanned in drawing.
Sometimes I will get a nice cad file to work with. with these drawings, I turn off all the extraneous layers that i don't need, and reset the layer colors to black and white. Often, though, the doors and windows are blocks on separate layers that I have to then modify to change the colors.

My script in VBA works perfect. Now i try to do the same with NET, but nothing happens. Here is the
Public Function CreateSelectionSet(ByVal SelectionSet As AcadSelectionSet, _
ByVal FilterCode As Integer, _ ByVal FilterValue As String) As Boolean
Dim iFilterCode(0) As Integer Dim vFilterValue(0) As Object
iFilterCode(0) = FilterCode vFilterValue(0) = FilterValue
[Code] .....
I can select something, but nothing happens... Where is the error?

How do I assign the blocks coming in from Architect's drawing (Partition Panels - about 50+ styles and each style is a different block) to a different layer along with those layer properties without having to explode & re-define?
I want to keep them as blocks but for uploading to a IWMS system which will only recognize certain layer names. They are changing over to the layer name I select, but their properties are not (example: color)

working with blocks, I want to be able to simple turn on and off certain layers of the blocks appropriate for the work I am doing at the time. However, no matter how I construct my blocks, on what layer i made them or insert them, I can only get one layer to turn on and off freely. Is there something I am missing with blocks to get it to work more smoothly?
Example... a door block with swing and frames. When you want to hatch a floor pattern, you have to click inside and outside the swing arc to hatch, and even then... there should be a line across the frame to close the opening... I just want to turn off the door and swing line, keeping the door frame and threshold line to make hatching easier.

I am finding the layer combo control in 2010 an annoyance. The drop down box does not access as many layers as did the version in 2009, and I find myself continually searching through the drop down box to reference a particular layer. How to rectify to have it similar to 2009?

I'm working on a map which contains a large number of data points. One set of points represents a number of signalized intersections. Each point has object data associated with it, including information that I want to use to theme. In order to get the theme to work correctly, I have exported the points to SDF and then connected to that file using the FDO.
Once connected to the data, I created a theme that I am using to display the points. The points are set to display as blocks (all the same block) which only vary in fill color based on one item of the object data. So far, all of that works; all blocks display as desired and in the correct color.
The problem that I am having is in trying to make a dynamic label a part of the block. What I want is to display the contents of one field from the object data as text immediately below the block. To do that, I open the block in the block editor, then add an annotative text field (mapanntext command). I set the properties that I want with regard to text size, position, rotation, etc., and set the value to be the appropriate field from the object data table. However, when I try to display these blocks in the map, the text does not show up. I've checked the basic issues (text would be large enough to see, layer is set to visible, etc.), but I can't figure why everything else displays with no text.

I have a dwg that is converted from vectorworks with 100+ blocks of different names. All line-weight and color is set to 0.00mm and white.
I want to be able to organize multiple Block into same layer so I can color them by layer and change visibility (hide/Lock) by layer. but when I select everything to organizes "by layer" only non-block line can be organized.
Is there a way I can change multiple block into same layer without exploding them?
I try:
1. select block and change layer in properties.
Failed.
2. "set to by layer"
Problem: layer of block is still not changed when open with reference edit.

I have a drawing which has multiple blocks. When I explode one block there is an identical block underneath on layer 0.
Is there a way in AutoCAD 2012 to select all the blocks on layer 0 and delete them so that it would leave me with just the one set of blocks?

I need to convert all polylines on layer to blocks. Each polyline gets replaced with a block that is near the approximate center of polyline. it can also be at the first or last node of pline. or just near the center. (polylines are rectangular).

I thought when you created a tool pallet with blocks on a certain layer and put them in your drawing that the block would be placed on the layer it was created on? When I put a block that was created on 0 layer it will insert on my current layer? These blocks are on a network and I am the only one that has rights to modify them.

I'm working on creating some blocks for our office. Basically it is a simple block with a few lines that remain and then a couple attributes you can click on and change. I have added the attribute and all is working well.
My only issue is I would like to make the text in the attributes to be bold. For some reason I can't see to do this. Is it not possible.
Basically I want to try and get some of the attributes to stand out more than others. I tried changing the color and the lineweight of the attibute (which worked the color is different) but when it prints it doesn't change at all.

I have received a drawing from another company that has blocks. When I try to rotate the blocks to an angle through the properties dialog box or by entering an angle at the command line, I am not able to. The value is always set to "E". I can rotate it graphically by placing points on the screen, just not through a key in. It seems like there is a lock on it.

I have a dynamic block symbol. It is a circle with two separate attribute elements at its side, with a line horizontally between them. No, this line is not a text underline; it is a separate line element that in one visibility state of the block must disappear.
My best results for blocks come when the element color of a block's geometry is set to "ByBlock" (attributes I leave as "ByLayer" color), and all of my elements, no matter what, I place on Layer 0. But in the case of this line, it always ends up matching the symbology of the block geometry. This I do not like.
When I insert a block, I use Attribute Editor to change the attributes' layer to the project's appropriate text layer. That way, in case I have to freeze a text layer, the attributes disappear also. What I want is for that line to be able to do the same.
Can an element's layer somehow be dynamically changed to automatically match the layer of another element, without having to Block Editor the block every time this is used from project to project?

I have inherited the task of maintining out companies tool palette for all standard blocks. In my efforts I have found a number is issues with the blocks and have made efforts to update the blocks, first using bedit and then by navigating to the palette directory folder where the .dwg files for the blocks are stored. Regardless of these files being changed the palette still inserts the block revision prior to my changes. I have even re-imported the template file to no avail.
Is there a way to have to palette reference the updated files or is there a better way to update these blocks so the palette recognizes the changes immediately?

I am using Autocad 2011 and created a dynamic block which turned out fine.
After making a copy of this dynamic block and doing some additions to this new block (added several flip parameters), I found that when I run my mouse over this new block it lags. I have attached the drawing which contains both the blocks. The one on top is the problematic block whereas the bottom one is the one I created first and made a copy of.

I have several script commands that insert items such as title blocks (xrefs) and page boundaries (blocks). The base point and INSBASE for all files are set to 0,0,0. However the blocks will occassionally come in at different positions. In some cases I can repeat the command multiple times and each time the same block will inset at a different position in the same drawing even though the insert point is set to 0,0,0.

We've recently converted all our microstation drawings to autocad now that the company has decided to go with one cad program company wide. One of the issues we are having after getting the drawings back from the this co. converting them is the cells to blocks conversion inside the drawing. when we open a drawing and see a "Fuse" block for instance and if it a has multiple inserts, it named them:
Fuse
Fuse_1
Fuse_2 etc....
is there a lisp routine or some command that would replace the "Fuse_*" blocks with "Fuse"..I've been searching the forums and know about the express tool Replace Block but need to be able to automate somehow. I thought about trying to rename each of the "Fuse_*" but of course it won't let you rename to a block name that already exists.
