Where are these height dimensions?
-
Hi, Gerrit.
Thank you for you post. I see you're a practical man.
Let's be practical then.
The purpose of these symbols which include certain numbers is indication of altitude (relative and absolute) of different levels in a building (floors, landings etc) and its surrounding. They are given on section drawings as opposed to similar symbols with same function used on site and floor plans. I think that the sketchy image I posted above gives an idea how they look like and what they serve to.
For now I'm sure they're used by architects in Balkan Peninsula region. I cannot say more than this about their usage by professions and regions. What I can say is that I haven't had any design during my architectural studies done without them. They are...a part of documentation, tiny but necessary.
How can we make them in SketchUp now?
We can draw few lines (which resemble the symbol) accompanied with text (say +5,70 [a comma used here is a decimal separator unlike some other countries]). Saved as a component the same symbol can be used on different places on section drawings (done by 'Create Group from Slice' function + 'make faces' plugin). The text itself differs from altitude to altitude so we need to make every particular component unique in order to change it - manually. The height value can be given by applying one of those TIG's plugins.
Or, we can use the method suggested by Jean.
Or, we can invent something more elegant. But no matter how inventive and imaginative we are it's for sure that one part of entire work must be done manually. We don't do that when we use the command for ordinary dimensional work. We just select the 'Dimension' tool, pick our reference points and - voilà! Later the entity info gives us possibility to change text position, font style, choose different endpoints and alike.
Move on to the next step: how to introduce more dimensionning options? Theoretically we can make some branches to the existing tool or we can make some new tool. A quick review of SU tools shows us that SU uses 'one tool - one command' principle. What I mean by this is that if you choose 'Push/Pull' tool for instance, you won't see any other sub-command. The other thing is that you're able to repeat the same pushing to different faces by simple double clicking on them or you can make an array by using the 'Move' tool.
So I doubt that SU developers would place any new command inside an existing one.What is left for me is to hope that one day I'll see a specific tool for getting an altitude value.

Aureus,
I am afraid there won't be any changes (enhancements) in the SU dimensioning tools. This sort of "job" has been taken over by LayOut and there you can create whatever elegant version (and custom variant) of any drafting symbols and dimensioning things - so the answer by the developers would always be "use LayOut instead".

Probably you're 100 per cent right, Csaba.
This time let's drop mentioning those ones who don't have LO. Still this imposes a bit of headache to a user who considers some other program for editing and documentation-preparing superior to LO or he/she is better accustomed to. Especially if we know that dimensioning is, if I may say so, one of the weak spots of SU. Even better example than mine is lack of angular dimensions but this has already been discussed elsewhere. (See the link http://productforums.google.com/forum/#!topic/sketchup/oCRCdqPzE5A)
Funny thing: John Bachus said "I'm not surprised that people find dimensioning important, but I am surprised that it made the top ten list". Well, I'm surprised that he's surprised.

Anyway, one thing that Jean said came under my attention.
He said in Canada they use another symbol for this kind of annotation.
I'm keen to see it.And not only that. I'd gladly see what kind of symbols and measures different professions from different regions use for their work.
So I was thinking to transform this topic a bit and turn it into something more fun and more educational. I hope that it can still fit into the range of topics allowed on this forum so the mods would agree and people are willing to take part.
My idea is: let's show those symbols accompanied with measures that different professions from different regions use for their work.
A small jpg or png image or pdf file (especially if drawn in SU or LO) would be absolutely desirable. A short text of explanation (like we use it here [where exactly] for that and that) would be required too.
Will we play this game for the sake of fun and education?
P.S. CatchUP no. 17 has just arrived. Let's have a look...

I'm keen to see it.In some jobs, we use this:
Level anotation.skp
We also use the Metric system and the coma as the decimal.Just ideas.

Thank you, Jean.
That's exactly what I had on my mind.
An interesting symbol, I guess you typed those values manually since the real length of that line is 2.59 m and not 258.95 m. But it doesn't matter, thank you again.
At least one thing I've learned from your post - the metric system is used in Canada and you use comma as decimal separator.From this perspective, when I look at Canada I can conclude: so close to the US - yet so different.

......since the real length of that line is 2.59 m and not 258.95 m. ....Hi Aureus,
Actually the edge length is 2.589500m with precision set to max.I know about, and have used the height symbol that described earlier on. Also this one that Jean presented. But whatever symbol you use, as long as you get the message accross.
Maybe you can get TIG's plugin "Add height above datum" working for you (maybe after donating to him
What if you integrate its 'height text entity' into a nested prefered symbol component that you explode after placing it. Haven't tried it enough.p.s. I don't use that many plugins (only basic ones like 'Weld'), since I basically only explain basic SketchUp tools and solutions to other users when questions arise. That's my main use of SketchUp, for answering questions. (which may sound strange

)I know, I just noticed that the separator is after "8" and not after number "2" which gives 100 times bigger value. But as I said, it's not that important since we saw at least one symbol and got accustomed with system used in Canada.
As for your attitude towards plugins...I think I understand you quite well, Gerrit.
Very often mastering native SU tools can bring you more benefit than trying to figure out how certain plugin work and why you don't get a desired result.I like to change methods in order to see what's the fastest one in a certain situation. And for example, I'd suggest everyone who has a lot of groups or components (like houses) placed on a terrain and need to edit them quite often to set up new keyboard shortcuts (in my case 3 adjoining keys) for 'previous view', 'zoom extents' and 'zoom window' and use them in order to shorten time of navigation and selecting. Not to mention that it helps a lot when you end up 'nowhere' (in the space between lines in wireframe mode).
On the other hand I don't know what I'd do if there wasn't 'Vector Push Pull' tool and his 'friends' - Joint and Normal Push Pull. In my case that's one of the most essential and used plugins.
Cheers.

Sorry, but you got me wrong. That's not at all my attitude towards plugins. And, even more, this would not do any justice to all the plugin writers who spend their valuable time and knowledge to write them.
My attitude concerning plugins was and still is (though for new users) that one needs to understand SketchUp first and only then gradually move over to also using plugins. (I didn’t touch any plugin during the first year playing with SU)
I enjoyed (and still do like) participating in discussions on how to tackle 3D modelling questions with SketchUp. As for plugins, I feel that when benefiting from using them in a professional way, I ought to pay for them or at least make a donation. My only “use” now is limited to seeing how they work and maybe some feedback to the writer. And since (for now at least) I don’t do anything other than helping out some users with their SketchUp issues, I normally stick to basic free plugins.
Plugins are a great way to level up SketchUp.p.s. Jean’s method to apply a customized height component including plain text is simple but will do quite well.

Gerrit said: "Plugins are a great way to level up SketchUp."
They are. But I feel there is more sense in pressing the SU developers to better the bare SU body in terms of efficiency, functionality, stability and overall performance than sitting and expecting people to spend their own time in making great plugins. After all, it's their program.
One more word about plugins. I remember that once (in one day precisely) I downloaded I huge bunch of free plugins. As Jean pointed very well, that's the situation when the SU interface does look like CATIA (if most of them are visible of course). But no matter how many plugins you have it seems to me that SU always starts much faster than those monster programs with million functions and several GB in size.
After trying them I deleted the most since I realized there are some that repeat some functions of other plugins and some other perform the same function with more reliability and speed. At the moment there are, I think, several plugins with 'make roof' function. Over the same base (face) some of them need one second to produce a desired roof and some of them ask several seconds for the same action and result.
I guess it all has to do with the algorithm applied. And you were totally right when you mentioned knowledge needed for this kind of work. And bright mind, I'd add.
It was a pleasure having you here again, Gerrit. Come around any time.
