Abstract

A method and apparatus for protecting a structure. A surface of the structure may be identified from a model of the structure. A perimeter of the surface of the structure may be identified from the model. The perimeter may be identified for the surface of the structure to be covered by a masking system during painting of the structure. A two-dimensional representation of the masking system may be generated for the structure based on the perimeter of the surface of the structure. Features for the masking system may be generated within the two-dimensional representation. Identifiers may be assigned to the features in the two-dimensional representation. Instructions for a forming tool may be generated based on the identifiers. The masking system may be formed from a sheet of masking material using the forming tool based on the instructions.

First claim

What is claimed is:

1. A method for protecting a structure, the method comprising:
identifying a surface of the structure from a model of the structure;

identifying a perimeter of the surface of the structure from the model, in which the perimeter is identified for the surface of the structure to be covered by a masking system during painting of the structure;
generating a two-dimensional representation of the masking system for the structure based on the perimeter of the surface of the structure;
generating features for the masking system within the two-dimensional representation wherein the masking system comprises a plurality of masks;
assigning identifiers to the features in the two-dimensional representation, wherein the identifiers are color coded so that die cuts are coded with a first color, kiss cuts are coded with a second color, and texts are coded with a third color;
generating instructions for a forming tool based on the identifiers;
forming the masking system from a sheet of masking material using the forming tool based on the instructions;
identifying a reference point corresponding to a location on the sheet of masking material;
arranging the two-dimensional representation of the masking system with respect to the reference point such that the masking system fits within a boundary for the sheet of masking material; and
arranging the plurality of masks with respect to one another such that a desired number of masks are formed from the sheet of masking material.

2. The method of claim 1 , wherein the masking system includes one of a single mask and a plurality of masks.

3. The method of claim 1 further comprising:
retrieving the model of the structure from a database.

4. The method of claim 1 , wherein forming the masking system comprises:
plotting the features on the sheet of masking material; and
cutting the sheet of masking material to form the masking system.

5. The method of claim 4 , wherein cutting the sheet of masking material comprises:
cutting the sheet of masking material to a first depth corresponding with a first type of feature of the masking system;
cutting the sheet of masking material to a second depth corresponding to the perimeter of the surface of the structure;
cutting the sheet of masking material to a third depth corresponding to a second type of feature of the masking system; and
wherein the first depth is for a kiss cut, the second depth is for a die cut, and the third depth is for a kiss cut.

6. The method of claim 1 , wherein the sheet of masking material comprises a first side and a second side having a backing material covering the second side, and further comprising:
positioning the sheet of masking material on a platform of the forming tool such that the first side of the sheet of masking material faces the platform; and
securing the sheet of masking material to the platform using a vacuum system prior to forming the masking system.

7. The method of claim 6 , wherein the second side of the sheet of masking material comprises an adhesive and further comprising:
removing the backing material from the second side of the formed masking system to expose the adhesive; and
attaching the masking system to the surface of the structure using the adhesive.

8. The method of claim 1 , wherein the features include a kiss cut and a die cut.

9. The method of claim 1 further comprising:
reversing the two-dimensional representation of the masking system.

10. A mask forming system comprising:
a forming tool configured to form a masking system used to protect a structure during painting, in which the masking system is formed on a sheet of masking material, wherein the masking system comprises a plurality of masks;
computer-aided design software configured to retrieve a model of the structure from a database; identify a surface of the structure from the model of the structure; identify a perimeter of the surface of the structure from the model, in which the perimeter is identified for a surface of the structure to be covered by the masking system during painting of the structure; generate a two-dimensional representation of the masking system for the structure based on the perimeter of the surface of the structure; reverse the two-dimensional representation; generate features for the masking system within the two-dimensional representation; assign identifiers to the features in the two-dimensional representation, wherein the identifiers are color coded so that die cuts are coded with a first color, kiss cuts are coded with a second color, and texts are coded with a third color; arrange the plurality of masks with respect to one another such that a desired number of masks are formed from the sheet of masking material; identify a reference point corresponding to a location on the sheet of masking material; and arrange the two-dimensional representation of the masking system with respect to the reference point such that the masking system fits within a boundary for the sheet of masking material; and
a controller configured to generate instructions for the forming tool based on the identifiers.

11. The mask forming system of claim 10 , wherein the sheet of masking material comprises:
a first side; and
a second side opposite the first side and having an adhesive, wherein a backing material covers the second side.

12. The mask forming system of claim 11 , wherein the forming tool comprises:
a platform configured to hold the sheet of masking material such that the first side of the sheet of masking material faces the platform;
a vacuum system associated with the platform and configured to secure the sheet of masking material to the platform prior to forming the masking system;
a plotting tool configured to plot the features on the sheet of masking material; and
a cutting tool configured to cut the sheet of masking material to form the masking system.

13. The mask forming system of claim 12 , wherein the cutting tool is configured to cut the sheet of masking material to a first depth corresponding with a first type of feature of the masking system and a second depth corresponding to the perimeter of the surface of the structure.

14. The mask forming system of claim 11 , wherein the backing material is configured to be removed from the second side of the masking system to expose the adhesive such that the masking system can be attached to the structure using the adhesive.

15. The mask forming system of claim 10 , wherein the features include a kiss cut and a die cut.

16. The mask forming system of claim 10 , wherein the computer-aided design software is configured to arrange the plurality of masks with respect to one another such that a desired number of masks are formed from the sheet of masking material.

17. A method for protecting a structure, the method comprising:
retrieving a model of the structure from a database;

identifying a surface of the structure from the model of the structure;
identifying a perimeter of the surface of the structure from the model, in which the perimeter is identified for the surface of the structure to be covered by a masking system during painting of the structure, and in which the masking system includes a plurality of masks;
generating a two-dimensional representation of the masking system for the structure based on the perimeter of the surface of the structure;
identifying a reference point corresponding to a location on a sheet of masking material; arranging the two-dimensional representation of the masking system with respect to the reference point such that t
