Yet another final update with the option to add tiles to the grid.

Other than tomot, anyone else interested in having the option to add the ceiling tiles?

One last update I hope.

One last update!!!

Yes, yet another update incorperating two suggested inhancements.

blajov, sorry about that but I only have SU8 Free at my disposal so there is no way for me to determine why that is the case.

You would think that if you created five faces and five edges and selected them that the first edge created would be associated with the first face created but you would be wrong.

The circles were created left to right and the edges from long to short. All were selected in the order that they were created. A Ruby snippit, created in Ruby Web Console, was executed with this results.

Major update posted today. Offsets can be created by three methods

Constant: Input number of offsets, distance between offsets, direction to
offset, either inside, outside, or both, and whether the selected face(s) and all
created faces are to be deleted, select No to keep faces.

Formula: Enter number of offsets, distance to first offset, direction to offset,
delete faces Yes or No, select operator + or *, and value to add or multiply by.

List: Select direction of offsets, delete faces Yes or No, a list of offsets
seperated by commas, choose type of offset either absolute or a delta value
to be added to the last offset value. If the offsets are a repeated sequence,
end the list with *X, where X = the number of repititions for the offset
sequence entered.

juanjin,

I didn't have any problem with your model. It has to be a odd coincidence that you were getting the error message. Although it is not required that all entities be components or groups, I would highly recommend it so that the plugin can better identify the selected face.

If you would care to attach the model to your post, I will try to determine what the problem is.

If an inference has been established to an edge on another face, that can confuse things and cause this error because the inferenced point is what you get and not the point you think you are pointing at.

Another day, another update!

Hallo sdmitch
Freedom to change the size is too important!
But still quite useful

If you have other standard sizes you would like to use, simply add them to the code. If you don't feel capable of doing that, tell me what you would like to have as size options.

Another day, another update!

juanjin, I didn't really choose the negative view. As you know when you draw a shape on the xy plane, its' face down and so that how the plugin was created and tested.

SUFractal, I chose starting in a corner to limit the number of partial tiles but there is no reason that the origin counldn't be in the center of the face.

This looks like a nice little plugin, but if I'm not mistaken, I think the grid "angle" at the perimeter is generated backwards isn't it? The angles should be reversed so that the ceiling 'pad' rests on the horizontal leg of the angle. The attached image shows a corner.

Thanks.

You are correct the perimeter pieces are backwards. It seem that it makes a difference if you are looking at the back or front side of the face. If you reverse the face, I think that will solve the problem. I need to add a statement to check the normal of the face selected to make sure whick way it is facing.

pilou, Just what are you trying to do?

A ceiling grid is the metal pieces that support ceiling tiles for a suspended ceiling.

Maybe but not sure how. Splitup just sub-divides a face. This plugin acutally creates the suspended ceiling "T" rails and "L" boundaries.

New version has been posted.

Retracing any segment of the closed curve with the Line Tool should create a face.

I wasn't able to solve all the problems but the new posted version is a major improvement over the one posted to this thread. In all but one test cases I devised, the plugin operated as expected. In the one case, the offsets were created in the opposite direction from the selected one. I'm still trying to figure out why.
