Just a thought, if you have a lot of text, you might pull up on the surfaces that aren't letters. Set your 3D text to have no thickness.
-
Make the 3d text without any 'thickness' [no-extrusion].
Place it on the surface of your 3d premade 'block'.
Explode the text's container so that its geometry merges with the block's geometry.
PushPull the block's surface 'up' - which will have the effect of 'sinking' the text.
Any 'island-faces' within the text's characters - like inside ABDOPQR04689%&@#etc - can easily be pulled up by a doing double-click on each one to match it to the block's 'plane'.
Adjust the block by using Fenced_Selection+Move to set its final dimensions as desired... -
You say those things so much better than I do.

Prepick PushPull, what is that?.
It was added in ver 8.
Previously, you selected the the PushPull tool, and then chose the surface using the PP tool's cursor. This also automatically registered a point (where you clicked,) on the face's plane, as the "base point of displacement."
But now, with pre-pick PushPull (which must NOT be disabled in Preferences > Drawing > Miscellaneous,) you can select a single face, (with the SelectionTool,) BEFORE chosing the PushPullTool,... and now you can choose ANY base point and ANY end point, for the displacement, ANYWHERE in the model. The points no longer need to be on the face's start and end planes, nor even within the face's bounds.
So, say that you already had a 3D shape, "shape1". And you drew a new profile for "shape2" that is somewhere else in the model outside the bounds of "shape1", but you wanted "shape2" to be the same height as "shape1."
You use pre-pick PushPull:
1) SelectionTool. Select the face of the "shape2" profile.
2) Choose the PushPull tool. (Note the difference in the statusbar help text.)
3) Choose a base point of displacement, at the bottom of "shape1."
4) Choose an end point of displacement, at the top of "shape1."Eureka! "shape2" is pulled up to the same height as "shape1."
In versions < 8, you either had to draw Clines, or measure the height of "shape1" first, and then manually enter that value into the VCB.

Tig you lost me at
@unknownuser said:Fenced_Selection+Move
. Otherwise it makes sense. -
I guess I have been pre picking pushpull all along, even in v7. I have a box "s" and box "z" in a model I want box "z" the same height as box "s", click on box "s" face and pull it even with "box "z".
Why "z" and "s" don't ask.. it has been a long day, and that's what I typed. :} -

There are several ways of selecting objects - as well as simply clicking on an object to select it you can make a selection using a [dotted] fence, by click+dragging the cursor and then a 2nd-click - depending on whether it's left>right or right>left it'll select everything wholly inside the fence, or in the other direction anything that's inside the fence, even if just partially - this is a typical CAD-selection 'trick' which makes it easy to select what you want. Also remember that you can adjust any existing selection thus - use Select +Ctrl to add newly selected object[s] to the selection, +Shift to add newly selected [unselected] object to the selection OR if they are already selected to remove them from the selection, or +Shift+Ctrl to remove newly selected objects from the existing selection. Also remember that a click on a face selects it, a double-click selects it and its edges, and treble-click selects it and any other geometry connected to it...So to move the face[s] of an object like your plaque adjust your view so you see it 'side on', then use a left>right selection fence to select the required edges and faces, connected edges cut by the fence but not wholly within the fence are not included in the selection. Then you can use the Move tool [constrained with say an 'axial lock' to keep it moved in a desired direction...] to relocate the selection by a distance you type in, or by snapping to an existing object or guide so it lines up...
On your PushPull question you can type in an exact +ve/-ve dimension to use OR pick on any other object to align to, AND the next PushPull will remember the last used value... so if you have several faces to realign to the same plane then you only need to adjust one as described, then still in the tool [or even later in the session assuming you haven't made any more PushPulls!] you can simply double-click on the other faces to reuse that value and PushPull those to match 'automatically'.

Ok Tig I have been that all along also, I didn't know what it was called
-
I like Tig's approach, fast and easy, now if someone could come up with plugin to center text on a face automatically...Here is what I mean, you have a box, you make a text and place it on the face of your box. Right click context "center (object)" X,Y,Z select center "X", and/or center "Y", and/or center "Z".
Much like making a "fence selection" in a presentation program over all the items. Then select left, right, or center, vertically, or horizontally or both in multiple steps. Inkscape call this function "Align and distribute objects".
There is something to keep the RBGs (ruby script gurus)busy for a few minutes. -
Yea.. the actual point for "Center" aligned text is really bottom center.
You can use inferencing to place the bottom center of the text, at the center of the face, then move it half the text's height, in the correct direction.
A "Move Text by Center" tool would likely use the text object's
bounds.center, SU's inferencing can find the dual midpoint of 2 sides of your panel, if you hold down the SHIFT key after the first midpoint inference pops up. -

No.. that is post-pick PushPull.
And yes TIG's tidbits are terrific.

Ok Dan I tried this as I understand it, I used the pencil tool as a center finder.
The panel is no problem, the problem is the text object. I grabbed a random serif font, didn't change the text so it reads ENTER TEXT. I picked up component center inference dots. No dots on the "E" characters, and I picked up the center of the"T" characters two centers on the "N, R, and X" one on each "foot".
What I have done in the past to center a text component on a face, is place the component at "eyeball center". Then using the tape measure tool, move in from both sides from the edge of the panel to the widest part of the first, and last letter. Then subtract the smaller measurement from the larger, divide the result by two then move the text in the correct direction, that amount. Well, this technique doesn't work 100% of the time sometimes I need to repeat the procedure. That is an operator error thing. Not working for me right now. -

Using a candidate jgp and jpg photo editor like GIMP to edge detect then use WinTopo to convert to a vector file vs raster. You can then open this with SU( probably have to go through CAD first because WinTopo can not export to SU ) and use push pull etc to create the desired sign. Very complex graphics gets problematic.

Or use a PNG with a transparent background.
Add it as an Image.
Use my ImageTrimmer to make it a cutout.
Simplify the edges to avoid too much 'pixelation' steppiness.
Explode it to merge with the 'block' geometry... -
To center the text you could also use TIG's CenterPointAll on both the surface where the text will go as well as the text. Then just grab the center point on the text and move it to the center of the face. I would imagine the center of the text's bounding box might not always be the real center of the text, though.

Good one Dave! What I did just now (this has become an temporary obsession)
I made my blank 3"x8" sign 1/16" thick, I did the text and used the tape measure tool to place guides at the center-point of the sign blank. then used my most used script centerpoint to place a guide point on the text, which was not as you observed the actual center of the text then moved the center of the text from a side and centered it top to bottom. I then exploded the text object went over a few edges, with the pencil tool. The I pulled up face of the blank another 1/16" to make a nice 3x8x1/8" engraved sign. I will post a pic later today, right now I need to go to work. -
I wonder if there'd be a graphic/scriptable way of determining the visual center of the text. It's been a long time since I did any typography. I'd need to do a refresher on that. I expect you could get it close and then eyeball it from there.
-
What reasons are there, for the text's Bbox center not being the center of the actual text ??
I tried adding whitespace (extra spaces after,) but the tool ignored the spaces.
Then added spaces before the text, the tool seems to include the extra space.
You can see it if you double-click the text before exploding it.

Dan, in the case of a word with only ascenders such as 'babble", the center of the bounding box would be shifted a bit higher and a word with only descenders such as 'paper' would have have a bounding box with a lower center than a word such as "man" that has no ascenders or descenders. Those are odd examples and mostly likely there'd be enough letters with both that might average out. Some fonts have much taller upper case letters than lower case ascending letters which could shift the center a bit. Some fonts have descenders that drop lower than their ascenders go up. This would also tend to shift the position of the center of the bounding box.
-
Dave I don't follow your reasoning.
The center of a text object is it's center. Of course it's actual height may be dependant upon whether it has ascenders, descenders, or none, and may dictate how much text is above or below the center.
But, it's center, is still it's center (taking it's overall height into account.)
And then there is the, situation when you create multi-line text objects. (The issue of ascenders & descenders is even more irrelevant.)
So.. obviously any tool needs to get the text block's overall height and width, before exploding, it.
