Creating a Molding Line

Recommended Posts

Needing help... 

 

I am trying to create the trim pieces in the image below in Chief Architect Premier X7  on a curved wall similar to the one in the image. I am having difficulty getting 3D polylines to work correctly. Any advice or quick tips?

The attached image isn't displaying for me - maybe it's my computer, or maybe the forum is having problems, or maybe it's the image.

Is it possible that the moldings are generating "inside" the wall surface rather than on the outside, thereby hiding them from your view?

That is possible, when I draw a straight line up and down in the elevation a line appears but will not let me select it in elevation view, only on the floor plan can I select the dot as it appears.

Lynsey, It is likely that the polyline is inverted.  Try the "Extrude Inside Polyline" option

I have tried messing with that option but I believe it is giving me issues because it is on a curved wall. I can get the top and bottom pieces to follow the curve but the sides are not facing the correct way. I have gotten them to appear on the other side of the wall but cannot seem to get it flipped.

You may need to make a new molding profile, flipping it in one direction or the other.

Sorry, I am not experienced with creating new molding profiles. Is there a video I might be able to watch?

Lindsay,  I just tried a test plan and 3D Molding Polylines do not seem to play well with curved walls in the vertical direction.  Unless someone comes up with a brilliant method you may have to go manual on this.  Draw your profile in plan view and rotate to match curve of wall,convert polyline to polyline solid and extrude with thickness setting and set elevation or go back to elevation view and adjust,then paint as required.

If you are using an existing profile you can find it in the library and left click then select "Place Molding Profile".  This works in plan view in X7 and also in elevation view but in elevation view you will get "flyers" that you will have to go looking for on the outskirts to be able to use.  I believe I tried it Eric's way the first time and it works but is quite painful on a curved surface because you need to make a custom rotated profile for each placement and it is a big guessing game.

"Draw your profile in plan view and rotate to match curve of wall,convert polyline to polyline solid and extrude with thickness setting and set elevation or go back to elevation view and adjust,then paint as required." 

 

This is the best solution I have come across. I have done a lot of toying with the program and this seems to work best. The only thing I have yet to figure out is how to connect the vertical trim piece with the horizontal piece and make it look mitered, so for now this is the best I can do. 

 

Thanks for everyone's help!

Lynsey, You can take a look at this other post that was a similar situation that I helped out with and did a little polyline subtracting to cope the joint with the molding polyline.  I am still not sure it is possible to get a true miter when working on a curve unless you turn the whole unit into a symbol or hire Yusuf.

Here are a couple other options that may be worth considering depending on the situation (one of which is only possible in X9)...

 

Option 1:

Use a window.

  1. Draw an arc along your desired wall profile to get an accurate dimension.
  2. Open a blank plan and draw your desired molding to the appropriate dimensions along a flat surface.
  3. Open a 3D view and convert to symbol.
  4. When prompted to select a Symbol Category, select Window and Add To Library.
  5. Go to your main plan and copy the arced wall section and paste into a blank plan.
  6. Open the wall, take note of the thickness, and then change the wall type to be one single layer the same thickness as your original wall.
  7. Select the new "window" from your library and place it into that wall. 
  8. Resize the "window" as necessary and/or click the Open Symbol tool and adjust the rotation and/or origin offsets as necessary.
  9. Open a 3D view and use the delete surface tool to delete the wall...leaving only the curved molding profile.
  10. Convert To Symbol but this time just add it to library as a normal fixture type.
  11. Place the new curved molding into your original plan.

It's really a bit easier than it sounds.  I guess the concept of using a window has been around for quite some time but it was only recently introduced to me by The Incomparable Yusef.  He and others have used a similar method by utilizing the "Treatments" tab and by creating and attaching the object to be bent as an exterior "Millwork".  I recently realized that just setting an object to be the actual window makes it a LOT easier to tweak it as necessary.

 

Option 2 shortly...

Option 2:

For anyone using X9 wanting to create simple arced picture frame type molding...Use a Wall Niche.

  1. Draw a wall niche on your arced wall.
  2. Set the depth of the niche to 1/16"
  3. Apply a casing to the niche.

You now have a molding profile that is very easy to change, reshape, and resize.  Just draw multiple niches as necessary for additional similar profiles.  This obviously has much more limited uses but is still pretty cool. 

 

You can also use a similar technique in pre-X9 versions to create the casing.  You just need to go through the steps of deleting surfaces and converting the curved casing to a symbol.  Of course you lose the ability to easily modify the casing but at least you know it's an option.

I appreciate and advice those of you, who need to know more about chief plus macros and utilize their benefits. Michael is man of the year!! He and his macros are very well appreciated too. 

 

I am going to learn the great works from your recent posts too.

 

Best.

      I cant seem to figure out what this "line" is that is attaching from the wall end through the cabinet. That 'square' section of walls is full length and then it switches to half wall for a peninsula. Sometimes it lets me work with it just fine and then whenever I try to make that base cabinet bigger than 45" wide and line it up against the corner, that faint angled line from the wall end to the cabinet corner (under BCB42R) appears.

      Is there anything I can do to either reduce or eliminate the lines the column moldings are producing in vector view?  I did convert the curve to a polyline...and divided the circle into very small parts...but it doesn't seem to help.  
       
      Any ideas would by great.  Thanks.
       
      Here's a couple pics...a sample plan is attached also. (Column Molding in Vector View.plan)

      Hi All
      I am wondering if you can create a new material from polylines.  I have made many new materials from images.  But in this instance I would like to make a series of metal circles to use to "paint" a hemi-sphere.  I could find an image to use to do this, but I want the circles to actually have real holes so light can shine through them.  I have attached an example of this for a light.  I am able to create a series of holes using a circle and the 3D molding polyline, multiple copy them and add to the library, but material is not an option.  This may not be possible...
      thanks

      Hi Chiefers,
       
      I have an interesting question for the pro's here. I am designing a very unconventional coffee kiosk with curved glulams and curved walls. I built the initial design by creating the 3D objects in plan view in a source file, then pasting the shapes into an elevation in a new 3D file, creating 3D shapes in the elevation. (See Kiosk Profile.jpg)

      Once the 3D Shapes were created I laid them out plan view in the 3D file and created the 3D structure. (Kiosk 3D.plan)

      I now need to put a window in the curved wall, and cannot figure out how to punch a hole in this shape. Any tips?
       
      Cheers,
