  1. I have done quite a search and have not found any good explanation to use entmake to insert a defined block, and scale or rotate that block upon insertion. The idea is to tag a line (pipe), and add the diameter, length, and cut-length of that pipe using attributes. I have the code to get the line information ready, and was working on the entmake for the attribute block to label the "pipes". Here is the code for the attribute block: (defun c:apd (/ LAY1 LAY2 LAY3 LAY4 CLR1 CLR2 CLR3 CLR4 LTP1 LTP2 LTP3 LTP4 FONT value1 value2 value3 rotation p) ;;;
  2. I have a rectangular device tag with polylines as wires. I want to rotate the wires, but since the device is rectangular, I end up with spaces at 90 and 180 degrees. Any suggestions would be greatly appreciated. Motion Detector.dwg
  3. Hi i have a plate and a shaft. i am able to constraint the shaft to be tangent to the plate and constraint it to be on a specified location. However. i need to make the plate rotate when the shaft rotates as if it is one unit. the shaft is to be welded to the plate. i tried everything within the joint or constraint. i also tried to weld the plate and shaft as single assembly but i couldn't weld with the shaft tangent with 0 offset. all i need is to fix the shaft on the plate and make the plate rotate with the shaft.

    CAD LT 2013 Block Authoring

    Hi, It's a bit difficult to explain my problem I would like to know how (or if it's even possible) to have an object follow a block in rotation (authored) without the object rotating itself. Kind of like a piston in a car, the piston will only move up and down but the rod and crankshaft will be in rotation (good example I hope). Or a luffing crane hoisting up and down and the counter ballast will follow the line of rotation but not rotate itself... Help would me much appreciated. Thanks.
  6. Good evening. After some extensive reasearch I could not find a way to solve my problem, so I have come here hoping you guys can save me yet again. I've spent the past three days trying to create this block and at the moment I'm quite frustrated. I'm trying to create a dynamic block with multiple actions. I need a flip, a stretch, a visibility and a rotation parameter and a basepoint. Everything works just fine until I add the rotation action. I need certain entities to rotate but the text to remain at 0 degrees. I learned that you can do that by assigning point parameter to move the t

    Rotation about an axis?

    I'm sure my beginner is showing, but I'm not sure how to constrain something to allow it to rotate about an axis. Basically, I have an axle which is grounded, and I need a wheel assembly to freely rotate about the axle. Any help would be GREATLY appreciated!
  8. Hi, I'm just trying my hand at learning to create some dynamic blocks, but need a solution to keep the text unrotated. I have attached a file of my troublesome file for you experts to look at, if possible. PileTest.dwg The file is basically a plan view of 4x foundation columns for overhead line towers (pylons). These towers can be different sizes and at different orientations, hence the dynamic options I have applied. However, when I rotate the block I want the text to rotate with it (to keep aligned with each column A, B, C, D), but I don't want rotation to be applied to the text,
  9. First of all sorry for my bad english. I wonder how do I change the default value of the angle that is between in the command UCS "specify rotation angle about X axis :" from 180.00 to 90.00 Thanks
  10. I'd like to share something I just discovered. It may be old news to many of you. Select a dimension. Select the text grip. Right click. You'll get a menu for doing some neat things with the text, such as moving it independently, resetting it, and centering it vertically. You can even rotate the dimension. I was trying to move some dimension text because the plan doesn't line up with the UCS. Either the text was upside down (reading left to right) or on the wrong side of the line (reading right to left). This beats exploding the dimension!
  11. Hello all and thanks ahead of time for any guidance. To simply put it, I am grabbing linework from a dwg and copying it from base point 0,0,0. in the drawing that I want to copy it into, I hit ctrl+v and type 0,0,0 to put it exactly where it needs to be. For some reason, that I cannot figure out, the 0,0,0 point in the two drawings are different...so I have to zoom extents and hunt for it 10,000feet away in model space. But that is not the main problem because I can always find it and move it where it needs to be. The main problem is that when I move the copied linework over th
  12. I have a property line that is N 36d19'52" E but needs to be N 12d52'18" E. The obvious and calculated rotation angle would be 23d27'34" but when I rotate the line by the calculated angle it doesn't rotate to the right angle. It's off by 0d11'10"!? When I draw a line by bearing at N12d52'18" E and inquiry the angle between the property line and the drawn line the angle difference is in fact 23d27'34". Is there a setting I have selected that I don't know I selected. I am in US survey feet, degrees, dd.mmss.ss
  13. Hi, I am currently doing a series of drawings with multiple viewports across the same level. To fit them all on an A1 drawing, I have to orientate the viewports in different fashion. This means that the symbols (blocks) look different depending on the viewport rotation. Is there any way to make it so blocks are displayed with a Rotation of X (say, in this case, '0') on each viewport? Thank you in advance. Any help in this would be greatly appreciated! Regards, Chris
  14. Apologies if this has been posted already - been searching everywhere for an answer to this one! Here is the problem with the process put simply: Start with a new drawing Drawn a rectangle. Place a block which has an attribute with a number at each corner. ie. 1-4. Convert all objects into one single block. (the attributes become nested). If you use data extraction and retrieve the attribute number, position X and position Y, and output to a table the information displayed is correct. HOWEVER, if you rotate the block and update the link the coordinates become incorrec
  15. I'm working with rotating wheels and am trying to figure out how I can go from 60 rpm to 30 rpm with no stop?
  16. I'm trying to animate the wheels on this crane (not as important as the later wheels I'm drawing up right now) and I can't get a full rotation. I tried everything to my understanding to use motion transition constraints against the rail or manually rotate them in the Studio. The former never worked for me and later keeps rotation 180 clockwise, then 180 ccw, and back and forth. Can anybody explain what I need to fix? I started a fresh document with no joints for I figure I must have been screwing up on that. If anyone can, please take a look at the files and see if he or she can solve this dra
  17. My company recently hired out some AutoCAD work. The task they completed was to load our drawings from pre-CAD days (1970s and 80s) into AutoCAD and update them with new piping and notes. Somehow, when they did this, the drawings in model space ended up sideways, but they are right-side-up in paper space. This is making it very difficult to work with the drawing in model space. A simple rotation of the entire model space drawing does not solve the problem because the xref files are correctly oriented, and they do not rotate with the added notes, etc. Also, it does not work to rotate just the n
  18. Hi I think this is a simple question for you guys but how do you find the rotation of a block within a drawing that I know the name. I want to create a new USC that is at the same rotation. I have tried Associated List 50 but there does not seem to be a rotation angle in that list is there some way to look into the properties and draw a rotation angle for there Here is a the code I tried [font=Tahoma][font=Tahoma](setq vfrt (assoc 50 (entsel "a3m_MS_viewframe_01000")))[/font] [/font]
  19. Ok. So I'm using a lisp routine that has been previously set up. It wouldn't display any of the current UCS coordinates. I think I fixed that. But now, I have caused a problem with the leaders. Specifically the line that is supposed to go underneath the N but above the easting. In WCS it works out just fine, but in the UCS it shoots off up and right. usually based on how far I am from the World Origin. Help! Below is the code. (Sadly I don't know exactly where the problem is) Main Function--------------------------------------------------------------------------- ;;;Function draws a lead
