Cutout Fitted to Profile Section

The third alternative (enlarged plate, reduced size of cut) is activated by assigning the following values:
SBH_CUTOUT_BEV = CUT
SBH_CUTOUT_BEV = CUT_CHECK
SBH_CUTOUT_BEV = CUT_DRAW
CUT means that the geometry is affected only in plate parts, not in views.
CUT_CHECK has the same effect but the system will check also in the modelling phase if the change of geometry will cause the cutout to "overlap itself". If so, a warning message is issued.
CUT_DRAW means that the cutout is adjusted also in views. Also in this case a warning message will be issued in case of overlap.
Only the parts of a cutout directly connected (welded) to the profile are effected. No additional environment variables are relevant in this situation.
|
SBH_CUTOUT_TIGHT=<d> |
Specifies a tolerance to be used in checking whether a part of the cutout is welded against the profile or not. Default value: 2mm |
|
SBH_CUTOUT_TIGHT_WEB=<d> |
Specifies a tolerance to be used in checking whether a part of the cutout is welded against the profile web or not. Default value: 2mm. |
|
SBH_CUTOUT_TIGHT_FLA=<d> |
Specifies a tolerance to be used in checking whether a part of the cutout is welded against the profile flange or not. Default value: 2mm. |
|
SBH_CUTOUT_SEGTOL=<e> |
It may happen that a line segment is welded partly against the profile section and that it partly is free. Then only the part of the line welded against the profile will be moved unless it extends more than <e> outside the profile section. Default value: 10 mm. |
Figure 1:3. Condition for introducing "step"in line segment of cutout.
A condition for this kind of change to function properly is that the part of a cutout between two straight lines is supposed to be a fillet that should be translated together with the surrounding lines without change of its size.
This method is normally supposed to be combined with bevel cutting of the part of the cutout against the profile section, currently only using a simple V-bevel, the angle of which is calculated automatically.
