        Step 11<\/h2>\n

        Set the current view to SE Isometric and the current visual style to 3D Wireframe. Enter the INTERFERE command, as shown below, to find the interfering solid. (Figure Step 11)<\/p>\n

        System Variable: SOLIDCHECK<\/p>\n<\/header>\n

        \n

        The SOLIDCHECK system variable toggles the solid validation on and off when a solid model is selected to be edited in the SOLIDEDIT command.<\/p>\n

        When the SOLIDEDIT command is executed, the current setting of the SOLIDCHECK system variable is displayed as shown below.<\/p>\n

        Command: SOLIDEDIT<\/strong><\/p>\n

        Solids editing automatic checking: SOLIDCHECK=1<\/p>\n

        1. The Separate option of the SOLIDEDIT command is used to separate two solids that have been joined together.<\/li>\n
        2. The INTERFERE command is used to check if two or more solids occupy the same If two or more solids occupy the same space, they will interfere with one another and in real life could not exist.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n","protected":false},"author":90,"menu_order":2,"template":"","meta":{"pb_show_title":"on","pb_short_title":"","pb_subtitle":"","pb_authors":[],"pb_section_license":""},"chapter-type":[],"contributor":[],"license":[],"class_list":["post-1169","chapter","type-chapter","status-publish","hentry"],"part":1107,"_links":{"self":[{"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/pressbooks\/v2\/chapters\/1169","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/pressbooks\/v2\/chapters"}],"about":[{"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/wp\/v2\/types\/chapter"}],"author":[{"embeddable":true,"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/wp\/v2\/users\/90"}],"version-history":[{"count":1,"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/pressbooks\/v2\/chapters\/1169\/revisions"}],"predecessor-version":[{"id":1170,"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/pressbooks\/v2\/chapters\/1169\/revisions\/1170"}],"part":[{"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/pressbooks\/v2\/parts\/1107"}],"metadata":[{"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/pressbooks\/v2\/chapters\/1169\/metadata\/"}],"wp:attachment":[{"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/wp\/v2\/media?parent=1169"}],"wp:term":[{"taxonomy":"chapter-type","embeddable":true,"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/pressbooks\/v2\/chapter-type?post=1169"},{"taxonomy":"contributor","embeddable":true,"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/wp\/v2\/contributor?post=1169"},{"taxonomy":"license","embeddable":true,"href":"https:\/\/opentextbc.ca\/autocad3d\/wp-json\/wp\/v2\/license?post=1169"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
