    How do you place a valley with out turning it into a surface and physically manipulating the roof surface to look like the valley?

     

    Every time I go to place a dormer it gives me this message.     “Dormer does not fit on roof surface.  Resize or reposition.”

    What an I doing wrong?   Tried different sizes and locations for the dormers.  Nothing works.  Same message every time.

    I have attached my model.

    MDD,

    Not sure, but what i always tried to do in this case is put the dormer in before i convert to surface. But converting to surfaces is the best way to get valleys unless you  just want to do exterior 3D. then i have a habit of just letting the roofs run straight through where ever they want to go. but if you do interior in the same model yes then you prolly have to convert to surface.

    In this case you might have to cut an opening in the roof and put the dormer in manually.

    Great model though good job!! Love the turret.

    as soon i get time I’ll put one in and repost it. (if someone doesn’t beat me with a better idea)

    Jack comment would be a great one to hear 🙂

    Thanks for the info Conrad.

    This project has been interesting.  I have been constrained by this project parameters.  The customer had a house that burned down.  They saved the foundation and floor.  It was a house built in the 70’s.  very “Brady Bunch” style.  They want a new “Victorian” style home within the existing foundation limitations.

     

    Thanks again.

    MDD,

    I made extensive roof videos years ago, they still work in v15 🙂

    This is the basic concept for your roof done as one roof. No Surfaces. Will accept Dormers.

    It incorporates a number of things I worked on in my testing of the roof tool.

    We all know you can select roof ‘arrows’ and adjust their heights in properties. So the Turret has it’s sides selected and raised.

    The front and back ‘porch’ and bump out are double pitched roofs 6/12 and 12 / 12. In that option you can adjust the ‘F’ setting which give control over the ‘depth’ of the 6/12 pitch , and where the 12 / 12 pitch begins.

    BUT the main technique is based on the movie ‘Ghost Busters’ . Remember the tool the had and the rule was ‘ Don’t Cross the Streams’. ?  That is applied in many of my roofs. It is breaking of a roof to create a new arrow , which allows you to create an alleyway, which has the overhangs set to 1/8″.  You can then pull opposing sides until the ALMOST touch. But NEVER cross with abutting roof.

    In the detail image you see the blue circles showing those breaks. And also that they are set to 1/8″ overhang.

    The same occurs where a Gable meets a Hip. Break , pull out the Gable a bit and Hip can be defined. Set overhang to a small amount to fool the eye, to think the Fascia of Hip and Gable are equal.

     

    I didn’t take the time to make the roof exactly as you need it, but I think this shows the basics. The truss manufactures or carpenters will make it work exactly but you can tweak the roofs in Envisioneer.

    Best roof tool in the business IMO.

     

    made it red to stand out  edit… the lower front bay roof is your original. edit 2 … will post a second time with bld in an hour or so.

    MDD , anyone

     

    Here is your bld.  As I said the roof isn’t exactly as you had it laid out .  Pay attention to the roof breaks. They occur at both Gable ends to get Turret and right HIP to work.  Just a simple break and then pull out the Gable so Hip can form.

    On the right and left of the double pitch porch / 12 12 roof you will see the two ‘alleyway’ rectangles. Those are two breaks which form a new arrow. You can spread them apart when creating , set 3 to 1/8″ overhang , two on right and left and the one horizontal little section.

    Once set, you can drag the porch dbl pitch towards each other, but do not let the overhangs touch, this will make the program create a different roof. Sometimes pretty crazy looking.

    Make sure auto save is off, if you goof up, you don’t want auto save to kick in and lose your ‘undo ‘ option.

    As I said, you can raise and lower things as needed, play with overhangs.

    You should also have the roof set to ignore next story. If it is ON it will cut a hole in the roof when roof gets too high.

    The walls you make the roof on,  extend to the roof. That makes 2nd story walls a bit hard if they need to extend. Theoretically you can copy the roof to the second floor but I can’t be sure odd things won’t happen.

    Your original roof surfaces are copied to a new location named ROOF.  Some walls were deleted that stuck through the roof .

    Good luck.

    Jack
