AutoCad :: What To Do With Symbols That Are Not Blocks
May 20, 2011
A consultant (of our office roofing department) provided CAD drawings of roofs depicting various roof symbols to represent equipment, this survey was years ago so I had no hands in it. The office roof inspector is hoping I may be able to change all the symbols to be industry standard symbols as the consultant used their own. Originally I told the roofing department it would be easy as I would just write a lisp and a script to change all the symbols to the new blocks...or so I thought.
As soon as I opened one of the consultant's files, those symbols...were not blocks, they were all comprised of lines, circles and hatches. In my frustration, I contacted the consultant and wanted a clarification on this, they simply drew the lines in and copied and pasted the symbols over and over again.
I got 240 drawings to literally update overtime. Each drawing can have an average of 30 symbols. Is there a way for autocad to recognize certain line patterns or hatch patterns (actually only the solids were used) and then store the x,y co-ordinates?
I've just started working for an architect and downloaded AutoCad LT 2013 today...is there some sort of menu where I can get basic door, window, etc. blocks? Or are these things I need to create myself?...I see the "tool palettes" box but it seems to have a random selection of stuff labeled "Imperial Samples" leading me to believe there might be other stuff elsewhere.
I am struggling to edit the standard set of blocks that comes with AutoCAD such as receptacles junction boxes etc. I want to edit the standard blocks and then save my changes for future use. Right now the blocks come in at different sizes then I would like. I try to edit them in the block editor however the changes I make do not apply to any other or new drawings that I make.
I have attached an image of the differing symbols and sizes. I want them to be consistently sized.
I made a post in the autoCAD LT section, URL...And to save you the jump (though there's none of the fixes I've tried)I'm having issues with annotative symbols jumping around the page. As far as I can tell, it happens on certain symbols when I add a second(or more) annotative scale to that symbol. I can reset the symbols so that they're all aligned and sitting 'on top' of each other, but when I switch to different viewports/plot or save/open the drawing again they've reverted to the position they jump too. In the past I thought it might be something to do with where the basepoint was within the block, but having changed that, I still had the problem.
Both the blocks I've had it happen with are reasonably simple (one's an 'Auto Air Valve' symbol with a mask behind the lines, the other is a custom 'Section line' symbol although that also has some properties to allow me to extend the section line) objects. With the section line symbol I mirror it to get the second half, which is the half it's having the problem on. I wouldn't expect mirroring an object would do it though. The odd thing is, it's only happened in some drawings that I've done, and only with some symbols (which were all created at a similar time, so should have the same issues?),
When working in a drawing, I don't see a selection for weld symbols in Annotate - Symbols. Are they not available in LT? Is there something I need to do to activate them?

i have this lsp, it works great but how can modify it if i want select with a window.? exemple: if i have 3 differentes blocks, i want to select them with windows and the lisp select all blocks that are identical of those 3.?
We have a new title block which now contains various fields to automatically populate the drawing number, number of sheets, issue etc. The problem we have is when we go to zoom all or extents on a layout tab it moves the layout to the right each time. If we only have one layout or we use a plain title block i.e. with no fields, the zoom works fine (layout stays put in the center). This is also true if we directly insert a field onto the layout - again no problems.
The cause of the problem only happens when a block containing a field is inserted onto the paper space of a layout and,there are multiple layouts containing blocks with fields.
How do I manipulate a height parameter all of the dynamic blocks in the drawing from one single field? Say a field located in the drawing properties or on the drawing itself.
For example: Multiple blocks of different walls of same height with other blocks of things on located on those walls, dependant on the wall height, all linked to and changed by a single field. Possibly a Wall Height field located in the custom tab of the drawing properties.
I can pickout each of the blocks and change them at the same time in properites menu because they all share the same parameter name. I would just like to have that height parameter of every block in the drawing, that has that specific parameter controled by a single field. Which I could enter a new height at anytime that would change every block in the drawing to that height.
We used a bespoke program to convert our drawings to Java applets for web usage. This does not cope with dynamic blocks at present and we have started to receive drawings from our clients using them.
I need to replace this with standard static blocks based on one of two criteria. Either:
1) Replace based on visibility state (have generic chair block with multiple different chair types set by visibility type, need to replace depending on which type it is set as)
2) Replace based on parameter (have table with size set by dimensions, need to replace with static block for each dimension)
I have over 100 blocks that I need to add the exact same objects and visibility state to. Is there a way to globally make this change, or even to copy the visibility states from one block to the next without having to recreate the states in each block? I thought I had previously run across a routine on here that would make changes to multiple blocks at once, but I can't seem to find it now.
I have a project in 3D that I would like to export to Stadd. This requires lines rather than blocks. Is is possible to convert the blocks in the attached dwg file to to lines that are centered on those blocks?
The AttSync command does what it advertises fairly well. My problem is that I have thousands of small blocks in a single drawing. (My current drawing has 2100 block references with four attributes in each one.) I may change the attribute values in a few of them and need to re-sync the attribute locations. When I run AttSync it updates every single block insertion. One of two things are desired:
1)Flag each block insertion as having been sync'ed, reducing the number of objects requiring synchronization when AttSync is called again. Provide a way to force all to be sync'ed.
2)Allow a selection set in the AttSync command after selecting the block to sync.
Either or both of these would a great time-saver for those of us with large numbers of blocks with attributes.
I built a building foundation for a grading plan and I have another building that is the exact mirror of it. I have tried to mirror it. Didn't work. I created a block of the feature lines and inserted it with a -1 x value but I can't explode it. I tried the regular explode and xplode. Neither worked. I can use the the block to draw feature lines over but it just seems so much easier if I could figure out how to explode the block.
I have the same block repeated multiple times in a drawing, and I want to delete the last attribute in all of the specific blocks. When I edit the block in block editor, the attributes do not show up. After I explode the block, there is no text. The attached image shows the properties of the block.
I am trying to update blocks for a client. Each block has a line of text with the block name in it. I would like to automate these with a field so that if the block name changes or a new block is created from that one, then the field would update as well. I am running AutoCAD LT 2012 currently.
I wish to have a single dimension alter the dimensions in a set of nested blocks, similar to shared parameters in Revit. For example, I have a circle that has a fixed diameter that I wish to control in all blocks. I have set the diameter to barDia so now I wish to manipulate the dimension from outside the block.
Am I able to share the parameter across all the blocks?
I was trying to alter the standard blocks on the tool palette. How I messed everything up but I basically have two huge problems now.
1. I am missing the necessary default blocks that should be under my edit block directory.....all the Aecb files. 2. Now when I try and put in a receptacle or any other standard block a triangle with an exclamation point shows up upon insertion.
I attached a picture of the "edit block definition" and the troubled symbols.
I have been working on a drawing with 3 different dynamic blocks for several weeks and everything has been working perfectly. However, all of a sudden this afternoon, the text in all 3 dynamic blocks disappeared and will not display on the screen in paper or model space, and does not print.
As best I recall, I was creating a polyline viewport when this text disappeared.
I cannot turn the text on in these dynamic blocks. The text in on layer 0 which is on, and is unlocked and unfrozen. Additionally I have turned on, unlocked and unfroze all layers in the dwg and this does not work. I have also checked the text layer in the block editor and it is on layer 0.
When I click on any of the blocks, all the information appears to be correct, ie: door numbers, text style, etc. The text, however, just does not appear. Also I have never set any invisible text parameters and when I open the block editor, nothing in the invisible text area is selected or select-able.
Previous versions of this drawing, which I saved yesterday, display all block text perfectly. Perhaps there is a setting I accidentally hit which caused this problem?
I have tried repeatedly turning on all the layers, unfreezing, unlocking, changing parameters in the Style menu. I closed Autocad and turned the computer completely off and back on again.
I have a program that plots all blocks to png - open a dwg, get a list of all blocks, insert each into an empty dwg, zoom extents, and plot using the OOTB PublishToWeb PNG.pc3. In the attachments is an example of the problem. When I do this manually from a layout, I get the correct image. When I plot from code using the same PC3 file, draworder is being ignored.
It works if I apply transparency to the block and use ps.PlotTransparency = True, but I would prefer not to have to tell the user to change the block definitions. Is there a plotsettings property I am missing?
I want to create some symbols which includes text. For example, I have a square with an "F" centered within the square. The problem I am having is when I insert the block into a drawing and rotate it, the "F" also rotates. Is there any way to make it so the "F" is always horizontal no matter how I rotate the block?
I've just started to learn how to use Annotative Blocks and i'm running into what is probably a very simple problem. I'm creating a block and want to assign annotative scales to it. Once created, I insert the block into the drawing I need to use it in, and the only scale that shows up is the scale that is active when inserted.
All the other scales I added when creating the block are gone and I then have to assign the scales to the block again. I would prefer not to have to manually assign the scales every time the block in inserted into a drawing.
when I modify a dynamic block, that change persists to all other dynamic block that I have in the drawing. For instance, when I stretch the tail of a section callout, every other section callout stretches as well, which is quite inconvenient as you can imagine. I need each individual blocks changes to be independent of the others.
Is there a way to update a symbol of one type, without the changes being applied to all symbols of that type in the drawing?
Example: If I have three Flag Note symbol's in my drawing from the same sketch symbol and the text reads 1, is there a way that I can change the text to read 2 in one of them without the other two flag notes updating as well?
