Right now I have to agree with the OP. I stopped using the Dimension tool in Sketchup a long time ago. For some reason, the inference "intelligence" that works so well with the other tools most of the time does not seem so smart in Dimension. It "infers" like it's had 5 bourbons too many. In SU, when I need to take off a measurement I just use the line tool, read its length in the Measurements window then hit Escape. This works great for me, however, I still need to display dimensions on my drawings, which brings me to Layout.
If the Dimension tool is clumsy in SU, it is far worse in Layout. I am not even going to start with its capricious snapping to points you don't want it to snap to (you have to extreme-zoom to be able to select the right point, but then you can't complete your dimension because its endpoint is now out of the frame and, unlike in Sketchup where you can move / orient your model, hit Escape and resume / complete your action, that doesn't work in Layout).
Here are 2 bizarre and infuriating behaviors the Dimension tool has been doing in Layout:
- In some viewports, it simply does not work at all. I select my start point (snaps to it with a little green circle), click and drag - nothing. No line. At times some artifacts appear - red dotted lines and such. I have not figured out what they may mean yet.
- In other viewports, the dimension forms correctly (even though the value is often incorrect, i.e. 29' 11" 9/16 instead of 30' in SU, but compared to the magnitude of the other problems that's a minor quibble). Other times it shows an absurd value like 9" instead of 30'. I infer that 9" is the actual paper dimension, although my start and end points snapped correctly to the geometry, and the Dimension style is set to Auto Scale. Why it would not pick up the model scale is beyond me. Sometimes it eventually displays the appropriate scale after a few tries.
In addition, Layout is slow and super laggy, like it takes the cursor a solid second to change shapes after I select a tool. Moving a viewport across a page can take 2-3 seconds. My .layout file is only 22MB and my workstation is reasonably fast, in fact I never experience any slowness working on 50-60MB models in Sketchup, except for save / autosave but that's my own fault because I keep my files on a NAS.
Sorry for venting yall. I am pretty fluent with Sketchup and it is a fantastic program. But I am new to Layout and honestly I have not had a pleasant experience so far. I don't mind the UI, it's just a matter of learning how it works and if that takes a little time that's fine, I expected a learning curve. But here it seems that basic functions are buggy, just won't work consistently or at all, and that makes the learning experience very frustrating. End of rant, and if you're still with me thank you for reading!
