Conversion of wireframe to ACIS solid models for 2 1/2-D engineering components

Abstract Wireframe models need to be converted to solid models as the latter tend to become more widespread, consistent and affordable. A conversion algorithm for manifold objects was defined to obtain ACIS, thede facto standard B-rep model from a neutral IGES wireframe model and was implemented in...

A conversion algorithm for manifold objects was defined to obtain ACIS, thede facto standard B-rep model from a neutral IGES wireframe model and was implemented in C++ in successive stages as follows. All potential surfaces are found first. The entities lying on the same surface are examined in order to form closed profile-loops. Loop nesting is examined according to a ray casting algorithm. Adjacency and nesting of loops is used in order to assign traversal directions to all edges according to the Möbius rule. Invalid profiles (those containing edges belonging to more than two loops) are searched for and successively removed. The final test is that of edge type. If the majority of edges turn out to be concave, the traversal sign of all edges is reversed, so that the body is solid in empty space and not the other way around. For engineering components the algorithm adequately resolves all singular cases.

Invalid profiles (those containing edges belonging to more than two loops) are searched for and successively removed. The final test is that of edge type. If the majority of edges turn out to be concave, the traversal sign of all edges is reversed, so that the body is solid in empty space and not the other way around. For engineering components the algorithm adequately resolves all singular cases.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">ACIS</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">CAD model conversion</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">IGES</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Solid modelling</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Wireframe modelling</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">The international journal of advanced manufacturing technology</subfield><subfield code="d">Springer-Verlag, 1985</subfield><subfield code="g">14(1998), 3 vom: März, Seite 199-209</subfield><subfield code="w">(DE-627)129185299</subfield><subfield code="w">(DE-600)52651-4</subfield><subfield code="w">(DE-576)014456192</subfield><subfield code="x">0268-3768</subfield><subfield code="7">nnns</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:14</subfield><subfield code="g">year:1998</subfield><subfield code="g">number:3</subfield><subfield code="g">month:03</subfield><subfield code="g">pages:199-209</subfield></datafield><datafield tag="856" ind1="4" ind2="1"><subfield code="u">https://doi.org/10.1007/BF01188415</subfield><subfield code="z">lizenzpflichtig</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_A</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_OLC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SSG-OLC-TEC</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_20</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_21</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_23</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_32</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_70</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_132</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_136</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_150</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_161</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2006</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2009</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2018</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2020</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2048</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2241</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_2333</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4046</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4277</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4307</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4313</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ILN_4319</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">14</subfield><subfield code="j">1998</subfield><subfield code="e">3</subfield><subfield code="c">03</subfield><subfield code="h">199-209</subfield></datafield></record></collection>

abstract	Abstract Wireframe models need to be converted to solid models as the latter tend to become more widespread, consistent and affordable. A conversion algorithm for manifold objects was defined to obtain ACIS, thede facto standard B-rep model from a neutral IGES wireframe model and was implemented in C++ in successive stages as follows. All potential surfaces are found first. The entities lying on the same surface are examined in order to form closed profile-loops. Loop nesting is examined according to a ray casting algorithm. Adjacency and nesting of loops is used in order to assign traversal directions to all edges according to the Möbius rule. Invalid profiles (those containing edges belonging to more than two loops) are searched for and successively removed. The final test is that of edge type. If the majority of edges turn out to be concave, the traversal sign of all edges is reversed, so that the body is solid in empty space and not the other way around. For engineering components the algorithm adequately resolves all singular cases. © Springer-Verlag London Limited 1997
