Setting accurate dimension for extruded text

[Anonymous]

Hi,

I just can't figure out how to set accurate dimensions for text.

example: I want to create two bodies: One letter A and the other one letter H. I need the letters to be exactly 60x60x60mm (no problem if text deforms a little).

What I do now is scale the object by calculating the scaling percentages but that's not 100% accurate (at least the way I do it). And I need it to be because afterwards I want to intersect the two letters to make a two-sided (don't know how you call a thing like that, maybe 3D monogram?) object where one side says A and the other says H.... must be easy to do but I just can't figure it out...

appreciate any help/tips

First sketch the text size doesn't matter too much and extrude to 60mm high. Now measure its size in the XY lets say it 50x55, use a non uniform scale and for the X  enter 60/50 and for Y enter 60/55 for Z leave it at 1. As long as your measurements where correct it should end up 60x60x60. 

If not export the design as an f3d and attach.

Edit got that round the wrong way should be 60/50 and 60/55

Hi Mark, thanks for your reply. This is basically the way I already do it. But I was hoping there would be an easier way to just say: length = 60mm instead of calculating scalingfactor...

When I see people's designs with a timeline full of move and align features it always puzzles me why they've not created the geometry where they need it. That said I noticed after making the screencast the text is not created from the corner of the construction box created with the text. Don't know why they bother with the box around the text if it doesn't fit the text. If you look at the attached file you'll see I used 2 joints to position the components exactly. 

In the screencast I've used 2 different methods to get the size of the original text. Using measure just clicking the text on the dialog copies it to the clipboard. Getting the bounding box from properties is quick but only give 3 decimal places and might not be accurate enough.

Looking at your original file I see I've got the orientation wrong. I've edited on of the joints in the attached file. Think it right this time.

I've picked up some nice workarounds in that clip so thank you. Although I still was hoping there would be an easier way this could work. Unfortunately having exact dimensions doesn't make the intersection any better. Apparently fusion doesn't know what to do with an intersection at same heights. I was able to combine two letters before (see example.f3d pls don't all the crap flying around 🙂  trial and error file) where it did work but that was when dimensions were not accurate. In your test file mark (test.f3d) I got a false result with combining. Any thoughts on what might fix it?

Which test file is that? The second one I uploaded with the joints positioning the 2 components combines OK but I'm not sure what you're trying to achieve. There can be problems when faces are collinear as there's no clear intersection between them.

I looked at the Test.f3d attached to your reply and noticed you deleted on of the joint. I've added it back in the attached file using the same orientation you were using abd the combine intersect still works, what else do you need?

thanks Mark, i've figured it out with your help. And some how combine/intersect does work fine when everything is perfectly aligned.
