Mtext Attribute Location / Alignmentpoint / Position

js75CAD — Fri, 01 Oct 2021 10:14:25 GMT

Hi All,

I am trying to swap one block for another and I have a multiline attribute, so I am trying to mimic the justification and alignment to be as per the original. I know that as a single line attribute, if the justification is Bottom left, I use position and if otherwise I use the alignment point. This works perfect!

Why does this not work with the Multiline Attribute but only when the justification is Left?

The IsMTextAttribute object gives me a new position that is Location, but this doesn't work either. I have tried the alignment point, the position even the attachment point, but for the life of me I cannot get the Right justified MtextAttributes to match that of the original block.

There is no subject matter on this that I can find anywhere. Does anyone have a hint that might get me where I need to be to move this attribute?

Hi,

Have a look at MText properties in the documentation specifically Location and Attachment.

After having edited the MText, to update the attribute, you have to reset the modified MText as MTextAttribute:

attributeReference.MtextAttribute = mtext;

_gile,

Thanks, but this doesn't work either. I am not sure why Autodesk go out of their way to make things so bloody difficult! How many points do you need? Location, attachmentpoint, alignmentPoint, Position... come on!

attNew.TextString = att.MTextAttribute.Contents Select Case att.Justify.ToString Case "MiddleRight" attNew.MTextAttribute.Attachment = att.MTextAttribute.Attachment attNew.AlignmentPoint = att.AlignmentPoint Case Else attNew.Justify = att.Justify attNew.AlignmentPoint = att.AlignmentPoint End Select attNew.UpdateMTextAttribute()

This is what I have so far. If the MTextAttribute is Left justified, no problem. But the minute it becomes right justified, it keeps throwing the text. Now I have managed to make it just move slightly, but the grip point is moving and I am not sure what that point is? Below you can see what I am trying to achieve.

You have to first check if the attribute reference is a MTextAttribute and make things differently if it is or if it is not.

Something like this:

if(att.IsMTextAttribute) { attNew.IsMTextAttribute = true; MText mtext = att.MTextAttribute; MText mtextNew = attNew.MTextAttribute; mtextNew.Location = mtext.Location; mtextNew.Attachment = mtext.Attachment; mtextNew.Contents = mtext.Contents; attNew.MTextAttribute = mtextNew; } else { attNew.Position = att.Position; attNew.TextString = att.TextString; if (att.Justify == AttachmentPoint.BaseLeft) { attNew.Justify = AttachmentPoint.BaseLeft; } else { attNew.Justify = att.Justify; attNew.AlignmentPoint = att.AlignmentPoint; } }

Thank you _gile!

I had already checked if it was (sorry i should have included that part of the code), but I misunderstood what you meant by the Mtext. I now know what I did wrong.

Admittedly, I still am struggling to understand the difference between all the points, but now I have this, I will start testing different scenarios to see how they change. I just wish they has some documentation on this.

Much appreciated and whereever you are in the world, have an awesome weekend!
