You do need to click the show button on the add-on as the dimensions are hiddden when you first open a Blend file

It looks like it does not work with instances. After making each mesh local / deinstantiation it, it worked.

@@ecrvtbzn Glad you found a solution. I don't think I used it on instances before so was unaware of the issue.

I'm getting this too. anyone?

Hey Jose, yes you can name it anything, I just find it easier to identify the dimension more quickly.

Hey there, the first thing to check is the objects you are importing have a face and are not only edge objects. If its a drawing from a CAD program you will need o either convert to mesh and fill with faces, or give the curves some thickness. That may not be the issue, just the first thought I had.

@@BlenderZenThank you. That points were ok. I found a way by mixing via he compositor the freestyle layer but I'll try to find out why.

The easiest way to make you object real world scale is to use the MeasureIt add-on and scale the object to the correct size. Ave a copy of your file first to test. If you know what the distance between two vertices are in the real world then add a MeasureIt dimension between them. In object mode apply the scale (Ctrl + A).Then in edit mode select it all and scale until the MeasureIt dimension is the correct size. Different applications use different units and this can cause differences between models.

@@BlenderZen Many thanks for the answer man

Hey Nils. Have you also combined both the “Blender render” and the “MeasureIt” render in the compositor?

@@BlenderZen Yes, I did. And the measurement numbers are displayed okay - not a high resolution and unsharp/pixeled, but they are at least displayed. However, the lines are still not rendered, or in a way that they are not visible in the render result image. It's really surprising that there is literally not a single tool for dimensions out there that does the job of SketchUp. I do not like SketchUp and I am much into Blender, but this is a show stopper for my clients. Im not a programmer, but a user, and I would really be interested to see if there is a bigger need for such a tool. I am willing to invest into that. Most of the advanced tools that may cover this need, such as BlenderBIM, MeasureIt_ARCH, Construction Lines and others are too unstable and buggy. MeasureIt does a great job, but totally fails when it comes to rendering. My goal is to not duplicate my work, so I want to model my clients buildings, making razor-sharp images from inside and outside, but also use that same model to create the 2d floor plan with measurement lines. Did not expect this to be so complicated to achieve. Thanks for reading and replying! LG, Nils Leideck

Using the Origin might be the answer. Asking loud always works :).

@@petrkutil7400 Well, still not the same as at the segment of one object. Moving the origins of both objects with the link dimension moves the dimension line indeed, but don't draw assist lines to the objects at end of the arrows.

What I found, it is easier to set the background of the editing viewport to white in the Blender's preferences, and the dimensions to black. Then simply shot a screenshot of Blender to print the draw with dimensions in any view you need. No need to set up camera and the render with composition of dimensions.

Hey Bill is the add-on still enabled?

@@BlenderZen I ended up shutting down blender and reopening it and that worked

Hey R0nald, good question. I never considered the amount of dimensions you can add. Testing here it seems you can add a great number, and probably more than you would need for any drawing.

@@BlenderZen thanks for the reply. I'm up to about 35 right now. What prompted me to ask the question was that I got so far and was unable to create dimension off a certian vertex. Turned out, I had that vertex dimensioned already but the dims were turned off. Is that normal behavior?

@@r0naldhuber578 Yes MeasureIt is off by default when you open a Blend file. Took a while to get used to that behaviour, but its actually better that way in my opinion.

Don’t think the dimensions can be exported as SVG, but the Freestyle render can be. Enable the add-on “Freestyle SVG Exporter”. This allows you export the freestyle image as SVG.
