      you mean like prizes and stuff?

      this is a fairly common situation in framing when an X-brace is required.. often, you're able to just trace them onsite but other times you can't (other walls in the way etc..).. either way, it's nice if you just have the right dimensions in the first place..

      another example of the same problem.. (2x4 wall frames connected by a brace)

      mini2.jpg

      so the the challenge is for you to show your technique (probably via screenshots, .skp, or video) showing the best way you can come up with to draw the brace board in order to obtain proper dimensions for it.

      [and i'll act as the judge πŸ˜† ]

            in step 2, how do you know where to draw the line ? (at which height ?)

            like i said earlier, your board has to be a predetermined width…

                        Does it has to be drawn correct in the first place?
                        I was thinking, drawing the profile of the board in the correct size, extrude, rotate it, taper off the ends. - too many steps?

                          ok.. i'll try to switch up the way i'm presenting the problem..

                          draw this:

                          (notice which way the 5 units are being measured.. if i measure 5 in the place you're suggesting, my board will no longer have a width of 5.. it will be too skinny)

                              Well if you had a true arc or circle you could find your exact intersection points. But there are no true circles in SU.

                                take as many steps as needed.. but for you, once you recognize the issue, you'll probably immediate think ruby as a means of solving it.. the way i do it is with a dynamic component.. there's a brute force method to accomplish it within sketchup itself but i'm wondering if i happen to be missing a method.. no solutions given so far will accomplish it..

                                [EDIT.. haha.. re:your post while i was typing this one πŸ˜„ ]
                                but no.. i didn't set out for it to be.. it's a pretty cool little challenge because of how simple it seems.. hopefully a plugin doesn't jump in too soon and spoil all the fun πŸ˜‰

                                    That sounds dangerous - most likely you'll get some minor accuracy issue somewhere ~0.00001 of whatever - something that eventually cascades into a nightmare! (thinking of all them imported AutoCAD plans I've had... x_X )

                                      yes.. that can happen and why i eventually went with a dynamic component instead (maths)

                                      for getting an accurate enough dimension for a framer to cut.. it's ok.. but to have something like that in a drawing where you may be inferencing etc for future parts of the drawing.. i agree, it's a no-no.. you can throw off everything else down the line..

                                        From tip to tip you have length A-C the hypotenuse on the board. You know the width of the board B-C so you can find A-B. So when you have a board A-B long exactly you can rotate it with snaps then trim it, but is the rotate operation inaccurate?

                                          rotate is accurate.. you just need something to snap to which is hard to get in this case..

                                          but what you're saying.. can you do that geometrically (as in, can you do it using only sketchup tools) or would you need a calculator?
                                          (currently, the only way i've been able to do it is with a calculator (well, i use the DC dialog for the calculator that can then adjust the position of lines))
