AutoCAD .NET :: MLeader Landing Rotation
Jun 12, 2013
I have an mleader with a single vertices point.
There's a thing called a doglength which enables a grip point that allows the leader to be repositioned.
Dim ml As MLeader = TryCast(Entity, MLeader)
ml.SetDatabaseDefaults()
m_leaderIndex = ml.AddLeader()
m_leaderLineIndex = 0
ml.SetDoglegLength(m_leaderLineIndex, 2.5)
I have a problem with the dogleg length in that I can't rotate it according to the current UCS. Is this possible?

what the difference is between the landing and a dogleg of a mleader? What is the difference between the properties:
EnableDogleg
DoglegLength
EnableLanding
LandingGap

I have a weird issue with Mleader landing lines.In AutoCAD 2012, I get only one arrow grip on mleader landing lines when I select an mleader (see image below) In AutoCAD 2010 - when I open the same exact drawing - I get TWO arrow grips when I select an mleader.

I have cut sheets following my alignment. I would like the mleaders I place in model space to be at zero rotation when I go to the individual sheets. Works fine for text if I check the "Match text orientation to Layout" box, but not for the mleaders. Is there a setting I am missing?

I am making a template file having title block with fields. I use this template for creating layouts and sheets using Sheet Set Manager and the fields will be updated from the data of SSM. Now i would like to add a dynamic north block to my template. The block could be rotated (i have this block in file itself) and rotation angle could be inserted. Now how can i add a custom field to SSM so that i could set a rotation angle for the project and thus every new layout or sheet created using the template has the north block rotated with the angle mentioned in SSM.
Here is the file...........

I want to rotate a drawing in my paper space, but without rotating it in model space. So that I still can work on it easily in model space.

I have a North Arrow that I would love to make into a dynamic block. I would like to be able to rotate the N that represents where the north direction is. But while rotating the N around the center of a circle I would like the letter itself to stay un-rotated. It seems simple, if I rotate the letter around the axis of a circle 90 deg, I would like the letter itself to rotate -90 deg on it's own axis. Of course this is easy to do manualy, but how do i do it so that rotation 1 automaticaly triggers rotation 2?

How do I make a leader, no text, no landing, grippers on both ends. Every time I go to grab the gripper on the non-arrow side of the leader it moves away from me . The line just moves away from the pointer at an ever increasing speed and distance).

I just upgraded to AutoCAD Lt 2012. In the settings, I was able to figure out how to automatically get a landing line and how long I want it to be. But! When I draw the leader to left of center, it puts the landing on the left side of the line. How can I turn that auto-directional thing off?

At a multileader when "automatically include landing" is set to "NO" or unchecked, then a small point (like that at the end of a dimension line) is inserted in the callout block, such as the circle, which then prints. This makes for less than clean drafting to say the least--is this normal? If so, (why?!), is there any way to NOT have those points print/show up?

how I keep the three risers shown in the image below, but extend the landings on the first and third run to avoid creating the angled corners. The angled corners show up when I manually edit the edges to bring the second run width down to match the first and third run width.
If I extend the landings, it tends to push one of the second run risers around the corner to the third run, and that screws up my design.

Just a quick (but possibly hard?) question. I have a multileader set up, but I also want it to automatically include a line which spans the vertical breadth of the text at the end of the landing. It's hard to explain, so I've put an image below.
Currently it's set up as a block that can change in height, depending on how many levels of text I tell it to fit to. Problem is, if I rescale my Multileader, I'll have to go back and rescale the block separately.
Now, possible to include such a feature in a Multileader such that it autoscales and auto lengthens, depending on the height of text?

I want to force the Multileader landing to go left when the program wants to automatically form it to the right. How can you choose/change the direction of the landing line and side on which the text will be placed.

I need to know how to eliminate my first tread being part of the landing. I have tried every possible combination of varibles I can find. It happens randomly. when it does if I adjust anything it comes back.

In 2010, when you did a multileader, on the landing you had an arrow grip on both ends and then the box grip in the middle.. Now in 2012 they have the landing set to where there is an arrow grip at one end closest to the text and the box grip at the other end....
Is there any way to set the multileader grips on the landing in 2012 the way they were set up in 2010?

When setting up a simple FK control curve on say the wrist for example, many times the control curve isn't exactly perpendicular to the local rotation axis of the joint movement, so when we position the control curve to be perpendicular to the joint - it has a rotational value added, but the rotational handles are lines up with the rotational handles of the joint that we want to move.
Freeze Transformations: then the control curves rotational handle go back to being skewed (out of alignment with the joints)
We want to Freeze transformations before constraining the curve, but we'd really to keep those rotations control handles to remain aligned with the joints rotational handles. This will make it an exact control when animating - grab the rotational handle of the curve, rotate it, and the joint will move exactly in the proper direction.
how to get the rotational handle of any control curve to run perpendicular to the shape after freezing transformations?

To summarize: It seems that compounding a path resets the rotation of the gradient to it's original degree of rotation.
Detailed version:
1. Create a shape.
2. Add a gradient fill. Note it's degree of rotation. Let's say it's set at 10°.
3. Now rotate the shape by any means (transform or rotate tool). Note the gradient degree of rotation has shifted the same amount as the shape was rotated (if it was rotated 50°, the gradient will show at 60°).
4. Make it a compound path.
5. Instantly the gradient shifts back to it's original degree of rotation of 10°.
It appears that when rotating a shape with a gradient, the rotation of the gradient is locked to the rotation of the shape. But when making it a compound shape it releases that lock and "remembers" it's original state. But that is only true as soon as you make it a compound path, but if you no go ahead and rotate it just a bit using the cursor (as opposed to selecting transform > rotate), the gradient will switch back to how you would expect it to rotate in the first place...
Workaround would be to make it a compound path before rotating the shape at all.

using AutoCAD 2009 (vanilla)
I got too smart for myself today in bringing an old drawing up to current standards...Everyone seems to want their block attributes to be zero - I have blocks where the attributes are best when they match the rotations of each blocks.
I have an old drawing that was rotated (as it should be) at approx 2deg.
I used a lisp routine to global edit all the blocks that needed to be at zero. BUT for some reason (and after hundreds of blocks were corrected), I noticed I now have two blocks that should NOT have been in the set have had their attributes rotated to zero....and the attributes should be at the same rotation as their block's rotation.
Because those two blocks have a fixed tic mark, I can click on the mark to see what the block rotation is, then rotate its attribute to that rotation, but I have hundreds of blocks! One-at-a-time sucks....
Any chance there is a GLOBAL way to edit an attribute rotation to match its own block's rotation?

I'm having a frequent but random problem with Multileaders where the landing distance will change on its own from its initial standard 1/8 inch to some relatively large negative distance which also causes the landing to disappear altogether. If I use the move trick for resetting all elevations to zero (Move 0,0,10e99 then 0,0,10e-99) the landing will reappear connecting the landing grip at the strange negative offset.
The problem seems only to happen when the leader is connected to the bottom right of the note.
When I remove the leader and add a new leader it appears correct but as soon as I save the drawing the affected Multileaders will again present this problem.

How to make Multi Leader end line landing or turn 90 degree vertical? I just want to use the leader point to the part and no text at the end of the leader. I guess the only way i know how to do right now is to exploded the M-leader and draw a line vertical down which is not recall proper way . Some people like to use just Leader not Multi leader but i like to use M-leader so i can enter the text in difference line. (See Pic below)

I need reading the values from an Mleader object that contains a block. I can get attributes from normal blocks with no problem, but I am struggling with this.
I can get all the way up to casting the attributes, but when I try getting the Attribute Reference, the code crashes. How do I get the AttributeReference from the AttributeDefinition? As it is now, if I declare the AttributeDefinition, the values return as nothing.
Dim acDoc As Document = Application.DocumentManager.MdiActiveDocument Dim acCurDb As Database = acDoc.Database Dim acEd As Editor = DocumentManager.MdiActiveDocument.Editor '' Start a transaction Using acTrans As Transaction = acCurDb.TransactionManager.StartTransaction() Try Dim acBt As BlockTable =

I have a method DrawMLeaderLine(Database db, Transaction tr, Point3d point, string text) that draws me a MLeader line to the given point with the given text as annotation. The MLeader line points to the midpoint of a Line entity. What I need is a binding between the Line midpoint and the MLeader line, so when I move or resize the Line, the MLeader line should follow! I already tried to solve that, using constraints, but it doesn't work for Leaders.
This is my code...
public static MLeader DrawMLeaderLine(Database db, Transaction tr, Point3d point, string text) { Point3d mTextLocation = point + new Vector3d(5, 5, 0); BlockTableRecord btr = tr.GetObject(db.CurrentSpaceId, OpenMode.ForWrite) as BlockTableRecord; MText mText = new MText(); mText.SetDatabaseDefaults(); mText.SetContentsRtf(text); [code]........
will be called from a different class...
Line line = DrawingUtil.DrawLine(doc.Database, tr, closestPoints.Item1, closestPoints.Item2); //Get midpoint of line double midPointX = (line.EndPoint.X + line.StartPoint.X) / 2.0d; double midPointY = (line.EndPoint.Y + line.StartPoint.Y) / 2.0d; Point3d midPointOfLine = new Point3d(midPointX, midPointY, 0); //Draw the leaderline MLeader leaderLine = DrawingUtil.DrawMLeaderLine(doc.Database, tr, midPointOfLine, "Connection");

How to set the total scale of a mleader in C#?
In German it's called: Gesamtskalierung
I had no Problem with this....
_mLeader.LandingGap = 6;
_mLeader.TextHeight = 60;
_mLeader.MLeaderStyle = _mleaderStyleId;
but the total scale is also very important for me. I try to add a picture with a red frame so you can see what I' missing.

So I recently upgraded from AutoCAD 2008 LT to 2013 (a huge jump), and I'm now tying to use MLEADER command.
When I create a new leader, the text I create for it does not display on screen or even in the command line while I am typing, which means I have an absurd number of typos, I'll get distracted mid-sentence and forget where I was, etc.
This is bad. I'm assuming there's some sort of system variable that turns this on and off?
Possible relevant info: leader scale is set to "annotative," leader style is "MTEXT."

I pulled in a survey from an outside vendor and was just going to work with what they have. Their MLEADERS are a different font than what I would like and changing the Text Style doesn't work. I notice in the properties for the MLEADERS that the contents don't have just the mleader text, but is says this instead:
{fSansSerif|b0|i0|c2|p2;W1;TEXTHERE}
Obviously its overriding with the text style with the bit of code. But is there a way to change it? Hitting the ellipses in the Contents properties just transfers control to the model space. I can't edit from the properties panel like you can with a DIM or anything. I don't remember how it functioned in '08 or '12. MATCHPROP also does not change the font.
Yes I could just create the MLEADERS but I feel it would take less time delete that fSansSerif junk than it would be to place and retype every single MLEADER in the drawing.

I am trying to use a lisp that will turn on a background mask on selected mleaders. I found the attached lisp here [URL]. it works good except the mask border offset factor is set to 1.5. I need the offset to be 1.0. When I look thru the lisp code it says the default is 1.0 but can be changed.
how I can use the lisp and get mask offset factor to be 1.0?
