Dim Scale Linear - Wipeout - Viewport - Annotation Scale

[VDAGPQ96]

To begin, I have been creating dynamic blocks with wipeouts for quite a few years now and have not experienced this problem until very recently. I am currently using AutoCAD LT 2024, Product Version U.63.0.0. I can boil it down to a very simple example. In model space, if I create a polyline square of say 6" x 6" and then add a wipeout of the exact same size behind it (ensuring that I pushed the wipeout to the back in draw order), then create a viewport in one of my layouts which has an Annotative scale of 1:1 and a Standard Scale of 1:2, I should expect that any dimension (DIMVERTICAL, DIMHORIZONTAL, DIMLINEAR) I put down in paperspace will give me 6" x 6". Also assuming ALL of the other properties (DIMFLAC, DIMASSOC, etc) are set correctly. However, I noticed that sometimes one dimension will be correct (e.g. 6" horiz) but the vertical ends up showing half scale (i.e. 3"). Looking into the properties of both dimensions, I noticed that the Dim Scale Linear value under Primary Units for the dimension showing the correct length is -2 while the dimension showing the half scale value is 1. I have several other objects with wipeouts within the same drawing, using the same dimension style that dimension correctly in a viewport. I have spent hours upon hours trying every help, forum blog and random post suggestion. Purge, -Purge, Audit, Recover, Write Block, OSNAP changes...you name it, I cannot find an answer to what is preventing some of these dimensions from automatically adapting to the viewport annotation scale for this situation. The only workaround I found is to use MATCHPROP which will make both Dim Scale Linear values -2. Great! But WHY is this happening in the first place?

Hi,

Annotation has nothing to do with the dimtext value.

Compare your dimensions, one is associated, the otheron not (or just partial), right?

I guess you selected not two points on your rectangle, but one on rectangle and the other one by mistake on the first dimension object!?

Is it possible? Check this out and be more careful by selecting the dim points, use object snaps, but on your rectangle, not the paperspace dimension.

@VDAGPQ96 Show your work: share that DWG file here please, point to the offending dims, it appears you have more than one DIMSTYLE and possibly Annotative features turned on that you probably never used before today (none of which are new to LT2024).

[VDAGPQ96]

Thank you for the quick reply. I could not send my working drawing but what is attached still presents the problem. On the layout tab you will see several dimensions, all of which are showing half scale except the one vertical dimension on the left which is correct. I am using the same DIMSTYLE for all of these. The most frustrating problems are the simple ones.

Thank for the file. Look at these images

By hovering over that PROPERTIES entry, AutoCAD/LT shows the variable name

If you edit the DIMLFAC variable at the commandline, is should be set to 1 as you create new dimensions

I am unable to reproduce your 19.00" in any way in your file right now, so... how did you create it so I can try to replicate it? What am I missing?

I've been playing around with this for a while now and found a few interesting quirks.  It has something to do with the wipeout in that object b/c as soon as you delete the WO, all dimensions in the VP display correctly (when re-dimensioned of course). One point to mention here that may help is that I have Object Snap On, Object Snap Tracking On and all OSNAP options selected except Quadrant and Apparent Intersection. And the object's "Insertion" point is at the bottom left vertices. So in regards to the 19" dim line...if I specifically command a dimension to the "intersections" of the top left and bottom left vertices, I get 9.5". But if I let the software automatically choose these two points, it picks an "endpoint" for the top left and the "insertion" point for the bottom left which then produces 19". But this "automatic selection" method doesn't work anywhere else in that object.

Indeed it does, your Wipeout is masking the rectangle's 19 dimension (rectangle is magenta below)

You could stop using WIPEOUT objects, they've always been troublesome: we use a solid hatch with RGB color 255,255,255 then DRAWORDER them into place. Have had no issues for 25-ish years now.

Thank you for looking into this. Your time is much appreciated!

As a P.S. to this subject; as I said earlier, I've been using these wipeouts for a few years now on AutoCad LT and full ACAD through a few versions (2020 to 2024), and never ran into this problem until a few weeks ago. Could it be that a recent update or patch is the issue? Also, it's interesting when you look at the properties of the WO, it shows that the size of it is 19W x 19H when in fact it is 8-1/2"W x 19"H. 

In any event, I will try using the solid hatch method you suggested.

Pure luck. But I am of the opinion your biggest issue is

"... and all OSNAP options selected except Quadrant and Apparent Intersection..."

Just having every possibly OSNAP on and active all the time is just not the way to go. I never did that and your block totally behaved when I dimensioned it.

You also may not know that most dimension commands (DIMLINEAR etc.) have a "select object" option: with your rectangle s an example, simply start DIMLINEAR command and do nothing more that selecting the vertical (or horizontal) elements of your blocks, then place the dimension. This is the better faster quicker dimensioning method for simple shapes. Try it now.
